in the present study , alkaline proteases were extracted from the viscera of z . ophiocephalus , r . clavata and s . scrofa and characterized , and their efficiencies in deproteinization of shrimp waste to produce chitin were investigated .
the enzyme preparations from z . ophiocephalus and s . scrofa retained about 24 % and 45 % of their initial activity after 60 minutes of incubation at 50°c , respectively . however , the proteolytic enzymes from r . clavata were completely inactivated in the same conditions .

with s . scrofa crude enzyme extract , two activity peaks were observed at ph 6 . 0 and 10 . 0 . the enzyme preparation was highly active between ph 8 . 0 and 11 . 0 , with an optimum at ph 10 . 0 . the relative activities at ph 9 . 0 , 11 . 0 , and 12 . 0 were about 94 % , 69 % , and 39 % , respectively , of that at ph 10 . 0 . the optimum ph for s . scrofa proteases was similar to those reported by esposito et al . [ 31 ] for proteases extracted from the viscera of colossoma macropomum and el hadj - ali et al . [ 4 ] for proteases extracted from striped seabream ( lithognathus mormyrus ) .
scorpaena porcus can grow to a length of 37 cm but is more commonly between 15 - 20 cm . it is browny or orangy in colour with lighter patches and numerous skin appendages , which make for good camouflage . the caudal fin has three dark , vertical bars , and there is a light spot between the eigth and ninth dorsal spine . behind the gill cover ( operculum ) there are usually two spines .
crude alkaline proteases from z . ophiocephalus , r . clavata , and s . scrofa showed optimum activity at ph 8 . 0 - 9 . 0 , 50°c ; ph 8 . 0 , 55°c , and ph 10 . 0 , 55°c , respectively . the crude enzyme extract showed a high activity and stability in high alkaline ph . these proteolytic enzymes remained fully active in the presence of non - ionic surfactants . they also revealed high resistance when incubated with 1 % sodium perborate .
goby ( z . ophiocephalus ) , thornback ray ( r . clavata ) , and scorpionfish ( s . scrofa ) were purchased from the fish market of sfax city , tunisia . the samples were packed in polyethylene bags , placed in ice with a sample / ice ratio of approximately 1 : 3 ( w / w ) and transported to the research laboratory within 30 minutes . after the fish were washed with water , their viscera were separated , rinsed with cold distilled water , and then stored in sealed plastic bags at −20°c until they were used for enzyme extraction .
to investigate the effect of temperature , the activity was tested using casein as a substrate at the temperature range from 30 to 80°c in 100 mm tris - hcl buffer , ph 8 . 0 for z . ophiocephalus and r . clavata proteases , and ph 10 . 0 for s . scrofa crude alkaline proteases . thermal stability was - examined by incubating crude enzyme extracts for 60 - minutes at different temperatures from 30 to 70°c . aliquots were withdrawn at desired time intervals to test the remaining activity at standard conditions . the nonheated crude enzyme extracts were considered as control ( 100 % ) .

thank you for taking the time to provide feedback on the iucn red list of threatened species website , we are grateful for your input .
justification : this species has a wide distribution . it is occasionally consumed but it is not removed at any threatening level , and is not believed to have any other major threats affecting it . it is listed as least concern with a need for monitoring and more data concerning the disparity of possible ranges , population trend and consumption level .

this is a demersal , non - migratory , solitary and sedentary species that lives over rocky , sandy or muddy substrata . in the mediterranean sea , it is often associated with posidonia oceanica meadows ( moranta et al . 2006 , deudero et al . 2007 ) . it feeds on fishes , crustaceans and molluscs ( hureau and litvinenko 1986 ) .
this species is not sought after for food or trade in west africa . however , it is occasionally consumed . in the mediterranean , this is a commercial species .
in the eastern central atlantic it is caught primarily as incidental catch but this is not believed to be a major threat . in the mediterranean , this is a commercial species and its main catching method are trawls , gill nets , trammel nets and long - lines .
to make use of this information , please check the < terms of use > .
the name of the genus is that the old romans were giving to this fish , with reference to the poisonous spines , which reminded the bites of the scorpions .
the name of the species refers to the sow , the female pig , to which it resembles , in the world of fish , due to its protruding shape .
the red scorpionfish is present in all the mediterranean , but the black sea . the , passed gibraltar strait , it has colonized all the atlantic coast of the old world , from scandinavia to south africa , including the azores , the canaries , madeira and cape verde islands . finally , like many species , it has gone northwards along africa in the indian ocean up to mozambique .
it can be found at 20 - 500 m of depth , but rarely exceeds the 150 m . its choice location is where the rocks mix with the sandy or muddy bottoms , but we find it also in the brackish waters . the juveniles often camouflage between the rocks of the backwash , and once more than 20 cm , the progressively go down , looking for a calm place for their sedentary life .
it is the biggest mediterranean scorpionfish , with a record of 50 cm and almost 3 kg .
the body is oval with an impressing head , not only due to its enormous mouth , but for the spines and the dermic appendices which protrude in the most unlikely places breaking the outline with a clear mimetic effect .
unlike other scorpionfishes , here the appendices grow up also under the mandible , slightly longer than the jaw .
both are armed by villiform teeth , that is , much thin and close one to the other forming bands : 4 - 5 series over and 3 - 4 under , not to talk about the teeth pushing out on the vomer and on the palatines .
the dorsal fin is unique , but well evident . in the first part we see 12 poisoned spiny rays , in the second , 9 - 10 soft ones . the poison glands , one per ray , are protected by a sheath which breaks at the impact , in the upper part of each spine . the quantity of poison is very small compared to analogous tropical species , but the bite s very painful .
in some cases there may be hypotension with fainting or dizziness . the poison is thermolabile and therefore a first remedy may consist in soaking the affected part into the warm water .
the mouth is enormous with villiform teeth . the mimetic scheme foresees even big yellow spots © giuseppe mazza
as the name suggests , the whole colour is the red , with irregular and differing spots from individual to individual , which may be also brown and change hues depending on the environment . all is in function of the camouflaging , with the chromatophores playing an important role , and are not rare , especially in the corraligenous places , the individuals with big pale spots : pink , orange and even yellow .
often , but this is not a rule , we can see a dark spot in the upper part , at the centre , of the dorsal fin .
the red scorpionfish , as it can be easily guessed from its obese shape , is an insatiable predator .
it reproduces with floating eggs , united in mucous small masses . the larval forms are therefore pelagic . the vulnerability index of this species is of 68 over 100 .

the management of red scorpionfish broodstock , is to be considered as a starting point to obtain spontaneous spawning in captivity and for future propagation technologies .
in my opinion , further experiments must be carried out , focused on : finding a suitable starting live food for red scorpion fish larvae , a suitable tanks environment to obtain a useful production of this important species .

these are solitary fish , territorial , and live on the bed . they remain totally immobile until they are threatened , and then they raise a small “veil” and stop after a few metres .
its reproduction is oviparous . it lays its eggs in spring and summer between the months of may and august .
it is a benthonic species of mainly rocky beds , although it is also found on sandy beds . it usually lives at depths of 20 to 200 m .
it lives in the mediterranean sea and the eastern atlantic ( from great britain to senegal ) .
when they are captured they raise their needles and seem to inflate with their mouth open , showing all their poisonous needles .
. it is an infrequent visitor to the coastal waters off the south coast and is unlikely to be seen very often .
is a benthic species found from the littoral zone down to a depth of around 800 m . usually seen motionless and solitary amongst rocks and algae on the seabed .
brown or orangy brown in colour and growing up to 37 cm in length .
occurs in water between 20 - 110 m , is a brighter orange colour and has less well developed spines behind the operculum .
spines of the dorsal , pelvic and anal fins of black scorpionfish have venom glands at their bases . the venomous spines cause an intense pain and throbbing to people stung by it . treatment is to immerse the affected area in water heated to tolerance level and to disinfect the afflicted area .
this species is also known as the small - scaled scorpionfish ( d . herdson , pers . comm . )

scorpion fish inhabit the mediterranean sea and have never been spotted in the black sea . can also be found in the atlantic ocean and around the british isles and some have spotted it near the canaries and senegal all the way to cape verde ! prefers rocky environments although has been seen in sandy or muddy bottoms at 20 – 500m depth . a dedicated hunter they hide in burrows during the day while coming out to hunt at night !
its a dedicated hunter . eating mostly other smaller fish aswell as crustaceans and molluscs .
this is a non migratory species . there is no known information on spawning or mating for this fish .
( chance of encounter red > 0 . 9 yellow > 0 . 2 )
so much the respect for this fish that cyprus has placed it on a stamp . we are only aware of cyprus and san marino placing this fish on a stamp .

age analysis revealed 15 age classes but 3 + and 4 + were predominant in the catch .
habitat : a demersal species living over stones or sand away from immediate coastline in waters from 20 metres down to 70 metres ; juveniles also in seagrass meadows .
behaviour : predators , waiting patiently for the catch . very inactive during the hours of daylight , preferring to use their perfect camouflage to lay in wait for prey . during the hours of darkness they become more the stalker hunter .
did you know ? very well known to anglers and divers alike , they have venomous spines on their gill covers and their dorsal fin . the venom is active after death , so take heed ( for treatment see l esser weaver ) . out of all the venomous fish families within the mediterranean this is undoubtedly the most common to encounter due to the habitat range . because of this it is regarded by many as the worst . this species is the largest in this family .

this week , after the amazing success of the last post , i will change the direction of the article and i will focus on the fishes with bad spines , it is , fishes with venomous spines , but focusing on the mediterranean species .
despite seas and oceans of the planet are inhabited by a high number of potentially dangerous animals for humans , understanding its danger for bites , electric discharges or for its consumption ; the truth is that in only few cases these animals attack deliberately ; so , accidents are that : accidents produced by ignorance or carelessness . we have to have into consideration that we are not a prey of this fishes , so : which is the sense that this animals attack us deliberately ?
these fishes with bad spines are catalogued as actively venomous animals , it is , they have a venomous apparatus with glands that produce poison and a mechanism that permits the introduction inside another animal , like spines or teeth . this poison are used to defend themselves or / and to capture their preys .
these are some tips to prevent possible injuries when you go to the beach or when you are diving . they are useful to avoid venomous fishes and other marine animals :
use full - body neoprene in waters with potentially dangerous fauna , like australia .
don’t put your hands inside cavities , cracks or holes if you don’t see the interior .
danger . in whiprays , the needle is placed far from the the base of the tail , what allows for a wide outreach , but only it is a defensive weapon . the needle is hard and with hooks in the edge . it is in its interior where are venomous glands , which acts on heart muscles . in addition to the wound , the symptoms are : nausea , diarrhoea , vomit , sweating , circulatory disruptions and anxiety .
can measure 210 cm , has a rhomboidal shape and in the central part of the back and in the tail it has bony tubercles . they live in coastal waters , where feed on crustaceans , cephalopods and small fishes . on the other hand ,
, that also inhabits in coastal waters , doesn’t have bony tubercles in the back , but in the tail .
description . with a robust body , scorpaenidae fishes have big pectoral fins and a wild and big head . its colouration is brown reddish and irregular .
danger . most of the species live on the rocks or behind corals , so the risk is on step on them . the poison produce a reduction of pressure and lung edema and an increase of pressure on lung arteries , and cramps . the hard spines placed in front of the dorsal fin , the three first of the anal fin and the two first of the ventral fins present poison .
is the biggest species in the mediterranean ( till 50 cm ) and live in rocky and sandy seafloors . it can be easily identified by long dorsal spines with separated membrane . on the other hand , the
has a short tentacle above each eye , has not appendixes in the chin , its size is about 20 cm and with a black spot in the dorsal fin . finally , the
description . these fishes has a long and laterally flatten body . the mouth is wide and orientated upwards .
danger . all the species live in sandy seafloors , where bury theirselves . the venomous spines are the 5 - 7 first of the dorsal fin and the spine in the gill operculum . the poison produce an intense pain in the affected zone and cause sweating , nausea and secondary infections .
can be identified by : a brown yellowish to gray body with dark spots and the first dorsal fin has six spiny spines . such can be the gravity of the bite that can be lethal . the
has a grey greenish to brown yellowish body ; with short , dark and yellow lines and with 5 - 7 spiny spines in the first dorsal fin .
description . they are typical species of coral reef and in lagoons in indian and pacific oceans , but one species can be found in the eastern mediterranean , where lives in rocky seafloors with algae . its body is oval and very laterally flatten , with a small head and mouth .
danger . rabbitfishes are shy , so it is difficult to be hurt by their spiny spines , which are all over the body : 13 in the dorsal fin , 7 in the anal fin and 2 more in the ventral fin . poison causes a hard pain , but it doesn’t persist so much .
mediterranean species . the marbled spinefoot ( siganus rivulatus ) has an olive light body with irregular brown spots . it can be confused with salema porgies ( sarpa salpa ) . it is an invasive species .
remember : you don’t have to be afraid of sea and nature . with common sense and respect towards nature you won’t suffer any harm .

proteases constitute the most important group of industrial enzymes used in the world today , accounting for approximately 50 % of the total industrial enzyme market [ 1 ] . they have diverse applications in a wide variety of industries such as detergent , food , pharmaceutical , leather , peptide synthesis , and for the recovery of silver from used x - ray films [ 2 , 3 ] . proteases are mainly derived from animal , plant , and microbial sources .
the most important digestive proteolytic enzymes from fish and aquatic invertebrates viscera are the aspartic protease pepsin secreted from gastric mucosa , and the serine proteases , trypsin , and chymotrypsin secreted from the pancreas , pyloric caeca , and intestine [ 10 ] . acidic proteases from fish stomachs display high activity between ph 2 . 0 and 4 . 0 , while alkaline digestive proteases , such as trypsin , are most active between ph 8 . 0 and 10 . 0 . the distribution of proteinases varies , depending on species and organs . digestive enzymes of several species of fish have been isolated from the internal organs including gastric , intestinal , and hepatopancreas [ 5 , 9 , 11 – 13 ] .
chitin , a homopolymer of n - acetyl - d - glucosamine residues linked by β - 1 , 4 bonds , is the most abundant renewable natural resource after cellulose [ 14 ] . chitin and its derivatives are biomolecules of a great potential , possessing versatile biological activities , demonstrating excellent biocompatibility and complete biodegradability . therefore , they have found extensive applications in pharmacy , medicine , agriculture , food and textile industries , cosmetics , and wastewater treatment [ 15 – 17 ] .
the main sources of raw material for the production of chitin are cuticles of various crustaceans , principally crabs and shrimps . chitin in biomass is closely associated with proteins , inorganic compounds ( such as calcium carbonate ) , lipids , and pigments . they all have to be quantitatively removed to achieve the high purity of chitins necessary for biological applications [ 18 ] .
conventionally , to extract chitin from crustacean shells , chemicals processing for demineralization and deproteinization have been applied . raw materials were first treated with dilute hydrochloric acid at room temperature to remove metal salts , particularly calcium carbonate , and then with strong bases to remove proteins [ 18 ] . however , the use of these chemicals may cause a partial deacetylation of the chitin and hydrolysis of the polymer , resulting in final inconsistent physiological properties [ 19 ] . an alternative approach to these harsh chemical treatments is the use of proteolytic microorganisms [ 20 – 23 ] or proteolytic enzymes [ 24 ] . bustos and healy [ 25 ] demonstrated that chitin obtained by the deproteinization of shrimp shell waste with various proteolytic microorganism had higher molecular weights compared to chemically prepared shellfish chitin .
viscera ( 20 g ) were separated and rinsed with distilled water , and then homogenized for 5 minutes with 20 ml of extraction buffer ( 10 mm tris - hcl , ph 8 . 0 ) with the use of tissue homogenizer . the resulting preparations were centrifuged at 8500 ×g for 30 minutes at 4°c . the pellets were discarded and the supernatants were collected and then frozen at −20°c and used as crude protease extracts . all enzymatic assays were conducted within a week after extraction .
sodium dodecyl sulphate - polyacrylamide gel electrophoresis ( sds - page ) was carried out as described by laemmli [ 26 ] , using 5 % ( w / v ) stacking and 15 % ( w / v ) separating gels . samples were prepared by mixing the crude enzyme extracts at 1 : 5 ( v / v ) ratio with distilled water containing 10 mm tris - hcl ph 8 . 0 , 2 . 5 % sds , 10 % glycerol , 5 % β - mercaptoethanol , and 0 . 002 % bromophenol blue . the samples were heated at 100°c for 5 minutes before loading in the gel . after electrophoresis , the gel was stained with 0 . 25 % coomassie brilliant blue r - 250 in 45 % ethanol - 10 % acetic acid and destained with 5 % ethanol - 7 . 5 % acetic acid .
the optimum ph of the crude protease extracts was studied over a ph range of 5 . 0–13 . 0 , using casein as a substrate at 50°c . for the measurement of ph stability , the crude enzyme extracts were incubated for 1 hour at 4°c in different buffers and then the residual proteolytic activities were determined under standard assay conditions . the following buffer systems were used : 100 mm sodium acetate buffer for ph 5 . 0 - 6 . 0 , tris - hcl buffer for ph 7 . 0 - 8 . 0 , glycine - naoh buffer for ph 9 . 0–11 . 0 , na 2 hpo 4 - naoh buffer for ph 12 . 0 , and kcl buffer for ph 13 . 0 .
the influence of various metals ions , at a concentration of 5 mm , on enzyme activity was investigated by adding the monovalent ( na + or k + ) or divalent ( mg 2 + , hg 2 + , ca 2 + , zn 2 + , cu 2 + , co 2 + , ba 2 + , or mn 2 + ) metal ions to the reaction mixture . the activity of the crude enzyme extracts without any metallic ion was considered as 100 % . the effect of nacl concentrations on the activity of the alkaline crude protease extracts was studied , using casein as a substrate , by increasing nacl concentrations in the reaction mixture .
the effects of some surfactants ( triton x - 100 , tween 80 , and sds ) and oxidizing agents ( sodium perborate ) on alkaline crude proteases stability were studied by preincubating enzymes for 1 hour at 30°c . the residual activities were measured at optimum conditions for each crude enzyme . the activity of the crude enzyme extract without any additive was taken as 100 % .
the swp was prepared in our laboratory . briefly , shrimp waste , collected from the marine food processing industry , was washed thoroughly with tap water and then cooked 20 minutes at 90°c . the solid material obtained was dried , minced to obtain a fine powder , and then stored in glass bottles at room temperature . the chemical composition ( proteins , chitin , lipids , and ash ) was determined .
the moisture and ash content were determined according to the aoac standard methods 930 . 15 and 942 . 05 , respectively , [ 29 ] . total nitrogen content of shrimp protein hydrolysates was determined by using the kjeldahl method . crude protein was estimated by multiplying total nitrogen content by the factor of 6 . 25 .
shrimp shell wastes ( 15 g ) were mixed with 100 mm tris - hcl buffer ph 8 . 0 at a ratio of 1 : 3 ( w / v ) , minced and then cooked for 20 minutes at 90°c to inactivate endogenous enzymes . the cooked sample was then homogenized in a moulinex blender for about 2 minutes . the ph of the mixture was adjusted to 8 . 0 , and then the shrimp waste proteins were digested with proteolytic enzymes at 45°c using en enzyme / substrate ratio of 10 / 1 ( unit of enzyme / mg of protein ) . after 3 - hour incubation at 45°c , the reaction was stopped by heating the solution at 90°c during 20 minutes to inactivate enzymes . the shrimp waste protein hydrolysates were then centrifuged at 5000 ×g for 20 minutes to separate insoluble and soluble fractions . the solid phase was washed , pressed manually through four layers of gauze , and then dried for 1 hour at 60°c . the protein content was analyzed to measure the protein removal . the press cake was packed in a plastic bag and stored at −20°c until further processing .
deproteinization percentage ( % dp ) was calculated by the following equation as described by rao et al . [ 30 ] :
where p o and p r are protein concentrations ( % ) before and after hydrolysis ; while o and r represent the mass ( grams ) of original sample and hydrolyzed residue in dry weight basis , respectively .
all experiments were carried out in triplicate , and average values with standard deviation errors are reported . mean separation and significance were analyzed using the spss software package ( spss , chicago , ill ) . correlation and regression analysis were carried out using excel program .
in order to estimate the number of proteases in the alkaline crude enzyme extracts , samples were separated by sds - page , and then proteolytic activities were revealed by casein zymography activity staining . casein zymography is a very sensitive and rapid assay method that detects nanogram of proteins , in contrast with sds - page which detects micrograms .
, all crude enzyme extracts showed several clear bands of protease activity with different molecular weights , indicating the presence of several different proteases . it seems that goby crude enzyme extract contained more proteolytic enzymes than the other ones as illustrated in
by the presence of at least five clear bands of proteolytic activity . this result suggests that at least five major proteinases were present in goby viscera . when comparing the different profiles , it can be observed the presence of at least one protease common with all crude proteases .
the activity of proteolytic enzymes was determined at different ph values from 5 . 0 to 13 . 0 . the ph activity profiles of the crude alkaline proteases are shown in
displayed maximum activity at ph 8 . 0 - 9 . 0 . the relative activities at ph 7 . 0 and 10 . 0 were 55 . 6 % and 81 . 3 % , respectively , of that at ph 9 . 0 . however , protease activity decreased significantly above ph 10 . 0 . at ph 11 . 0 , the activity was approximately 5 - fold lower than that at ph 9 . 0 .
effect of ph on activity ( a ) and stability ( b ) of alkaline crude protease extracts . the protease activity was assayed in the ph range 5 . 0–13 . 0 using buffers of different ph values at 50°c . the maximum activity of each crude enzyme extract was considered as 100 % . the ph stability was determined by incubating the crude enzymes in different buffers for 1 hour at 4°c and the residual activities were measured at the optimum conditions of each enzyme preparation . the activity of the enzyme before incubation was taken as 100 % . buffer solutions used for ph activity and stability are presented in section 2 . values are means of three independent experiments .
the optimum ph for the crude protease of r . clavata was ph 8 . 0 . the relative activity at ph 9 . 0 was about 94 % . however , an appreciable decrease in activity was observed above ph 9 . 0 .
. interestingly , the three crude enzyme extracts are highly stable over a wide broad ph range , maintaining about 100 % of their original activity between ph 5 . 0 and 10 . 0 after 1 hour of incubation at 4°c . the enzymes retained more than 83 % of their activities at ph 12 . 0 . our results showed that goby proteases present a high ph stability compared to the others crude enzyme extracts .
optima temperatures for activity of crude alkaline proteases were determined in order to assess their suitability for biotechnological applications . the relative activities at various temperatures using casein as a substrate are reported in
. the crude proteases were active at temperatures from 30 to 70°c . the optimum temperature for
proteases was 55°c , however , alkaline proteases from goby and thornback ray displayed maximum activity at 50°c .
effect of temperature on activity of alkaline crude protease extracts . the temperature profile was determined by assaying protease activity at temperatures between 30 and 80°c . the optimum activity was taken as 100 % . values are means of three independent experiments .
the relative activities of goby proteases at 40 and 60°c were 54 % and 70 % , respectively . however , an appreciable decrease in enzyme activity was observed above 65°c , due to thermal denaturation . thornback ray proteases were more active at 60°c than the other crude proteases , retaining 90 % of their activity after 1 - hour incubation . however , the relative activities of z . ophiocephalus and r . clavata crude proteases were 70 % and 45 % , respectively .
. enzyme preparations from goby and scorpionfish are highly active at temperatures below 40°c , while that of thornback ray were stable at 30°c . goby crude enzyme remains fully active even after 60 minutes of incubation at 40°c , indicating that this crude enzyme might be used under mild heating conditions . however , at higher temperatures proteases were inactivated .
effect of temperature on thermal stability of the crude alkaline proteases from goby ( a ) , thornback ray ( b ) and scorpionfish ( c ) . the temperature stability was determined by incubating the crude extract at temperatures from 30 to 70°c for 1 hour . the residual enzyme activity was measured under the standard conditions assay at different times . the original activity before preincubation was taken as 100 % . values are means of three independent experiments .
the addition of cacl 2 and mgso 4 increased the activity of crude protease extracts of goby and scorpionfish . ca 2 + increased the activity of crude proteases from goby and scorpionfish to 110 % and 129 % , respectively . these results indicated that ca 2 + was very effective in improving the activity of the crude proteases . the enhancement of protease activity in the presence of calcium may be explained by the strength of interactions inside protein molecules and the better stabilization of enzymes against thermal stabilization . however , the activity of r . clavata crude enzyme was not affected by cacl 2 .
the ions ba 2 + affect partially the protease activity with a relative activity between 87 % and 96 % . however , fe 2 + and hg 2 + affect greatly the activity of all crude enzymes . the presence of 5 mm nacl and kcl did not affect protease activity .
all the commercial detergents contain hydrolytic enzymes such as proteases . in addition to activity and stability at high ph range and various temperatures [ 33 ] , enzymes incorporated into detergent formulations must be compatible and stable with all commonly used detergent components such as surfactants , perfumes , oxidizing agents , and other additives which might be present in the formulation [ 34 ] . furthermore , detergent enzymes should be stable during storage and active during washing in the detergent solution for a long period of time [ 35 ] .
the suitability of crude alkaline proteases as detergent additive was investigated by testing their stability in the presence of some surfactants and oxidizing agents . as shown in

larks are characteristic birds of the open landscapes like grasslands , steppes , stony plains , and heaths . most larks prefer areas with sparse vegetation . some species , including the wood lark and flapped lark ( mirafra rufocinnamomea ) , depend on a mixture of vegetation types within the same habitat , such as grasses for nest - building and scattered bushes and small

eremophila alpestris occasionally acts as a host for parasitic cowbirds . eremophila alpestris young suffer from cowbird parasitism because the parents neglect them to take care of the cowbird young . cowbirds lay eggs in the nests of eremophila alpestris , and when they hatch , the horned lark parents care for them , which takes away from the care of their own eggs . as a result , the cowbird chicks thrive and the eremophila alpestris chicks suffer . cowbird chicks are much larger than horned lark chicks which enables them to devour all the food the parents bring before the lark chicks get the chance .
duets can be so precisely coordinated that partners sound like a single bird ,
says behavioural ecologist paweł ręk of the australian national university in canberra , who studies magpie - lark displays .
the magpie - lark is mostly ground - dwelling , and is usually seen slowly searching on the ground for a variety of insects and their larvae , as well as earthworms and freshwater invertebrates .

17–18 cm ; c . 32–47 g . medium sized , densely streaked , relatively long - legged lark with long neck , long slender bill with distal half decurved , rather short wings . . .
in mainly insectivorous larks , the male is larger and has a longer bill than the female . this is most conspicuous in the greater hoopoe , the long - billed lark , and their relatives , which use their slender and decurved bills for digging in the ground in search of insect larvae . sexual dimorphism in bill and body size also occurs in the bar - tailed lark ( ammomanes cincturus ) and gray ' s lark ( a . grayi ) , which feed mainly on seeds . such differences in size enable both sexes of the same species to exploit different food resources within the same habitat .

to build its nest , the magpie - lark gathers plant fibres and uses mud like mortar to plaster everything together . it then lines the nest with soft grass , tufts of fur , feathers or any other cosy material it can get its beak on . nests are commonly on firm horizontal branches . it lays 3 - 5 eggs . depending on conditions , breeding is usually from august to february , and the magpie - lark lays 3 - 5 eggs .
larks have a crescent shape across their breasts . the crescent shape often signifies lunar qualities , and the moon is often linked with the concept of self . therefore the lark reflects the inward journey that’s often associated with self - discovery . this goes hand in hand with their singing , something that , for humans , is often considered a private activity and a deep reflection of inner self . lark encourages us to explore our inner selves and sing out loud .

magpie - lark males and females are similar from a distance but easy to tell apart closer up . female have a white throat and males have black throats and black eye - stripes . juveniles of both sex have the white throat of the female and the black eye - stripe of the male .
its habit of rising swiftly heavenwards and as rapidly falling to earth might make the lark a symbol of the evolution and involution of manifestation . passing successively from earth to heaven and from heaven to earth , it links together the two poles of existence and acts as an intermediary . thus the lark stands for the marriage of heaven and earth since it flies high up into the sky and nests at ground level among scraps of dried grass . its flight into the bright dawn light suggests youthful enthusiasm , ardour and happiness in being alive . by contrast with the nightingale , its song is a song of joy .

history of the crested lark in the mediterranean region as revealed by mtdna sequences and morphology

the horned lark has sandy brown upperparts , a white belly , a yellow throat and black bib , and a black patch below each eye . it also has two small black tufts , or “horns” that are not always visible . different subspecies vary somewhat in the coloration of the throat and upperparts . in flight , horned larks show mostly black tails with narrow white edgings .
at the same time in the northern hemisphere , the bering land bridge , the continental shelf between siberia and alaska , was exposed . the horned lark spread from asia into north america along this land bridge . its recent breeding range in north america reaches from northern alaska to the gulf of mexico , and a separated population established itself on the andean slopes of bogotá , colombia .
most larks swallow whole seeds , which are crushed in their stomach using grit . indigestible remains are ejected as small pellets . larks in the genera calandrella , eremopterix , and melanocorypha de - husk seeds in a finchlike manner , fixing the grain between the tongue and palatine and breaking it up . crested larks , wood larks , and skylarks remove husks from seeds by beating them against the ground . they use the same technique for removing the legs and wings of large insects . like the song thrush ( turdus philomelos ) , greater hoopoe larks crack the shells of snails using stones like an anvil . the same behavior was observed once in the crested lark in morocco , but never in central europe . the greater hoopoe lark also frequently drops snails onto stones until their shells break .
monogamous . only lark species building nests frequently on top of low shrubs , up to 24 in ( 60 cm ) above ground . also building cup - shaped nests on ground . two to four eggs incubated by female for about 14 days . both parents feed young , which leave nest after 12–13 days , before being able to fly . young remain for at least one month with parents .
the female horned lark selects a nest site on bare ground , apparently with no help from her mate . she either chooses a natural depression in which to build the nest or excavates the site herself , a process that can take a couple of days . to dig a cavity , she uses her bill to loosen soil and flip it aside , sometimes also kicking dirt out with her feet .
when i turned the models on , a female magpie - lark came along together with a group of other birds , mainly noisy miners and australian magpies , and they all together attacked my birds ,

6 . 7 in ( 17 cm ) ; male 1 . 3–1 . 8 oz ( 37–52 g ) ; female 1 . 3–1 . 7 oz ( 37–48 g ) ; not as large as skylark , more robust , with stronger bill and longer crest . uniformly dull - colored plumage , upper - parts and breast heavily streaked , sexes alike . very similar to thekla lark , its sibling species .
the colonization of australia by the australasian bushlark ( mirafra javanica ) and of north america by the horned lark happened in the pleistocene at the latest . during pleistocene glacial periods , sea level was much lower than today . sumatra , kalimantan , and java ( sunda shelf ) were therefore part of asiatic mainland , and new guinea was connected to north australia via the torres land bridge , forming the dispersal route of the australasian bushlark .
song is performed during aerial song - displays while males circle about their territories . some species rise almost vertically from ground or perch and ascend up to 330 ft ( 100 m ) or more before gliding or dropping with closed wings back to the ground . continual hovering and singing is characteristic for the skylark . several lark species frequently utter their songs from the ground and elevated perches such as stones , tops of bushes , or trees .

larks are of african origin , and that their first radiation took place on this continent . madagascar was colonized once by the african ancestor of the madagascar lark ( mirafra hova ) . today , several mirafra larks occur in asia . however , it is not possible to say how many species colonized asia independently , since it is unknown whether the group of asiatic mirafra species is monophyletic , i . e . , evolved from one common ancestor .
the crested lark reached central europe from southwestern and eastern europe later than the skylark and was widespread in the sixteenth century , but receded during the little ice age in the seventeenth and eighteenth centuries . however , it spread into central europe again from the middle of the nineteenth century onward , helped by global warming and man - made habitats such as roads and railway stations . crested larks even reached scandinavia in 1900 , but became extinct in the 1990s , possibly because of climatic change .
all lark nestlings have a characteristic brightly colored gape , with one black spot inside the tip of the upper and lower mandible . there are two black spots on the base of the tongue in ammomanes , some certhilauda , and mirafra ; and an additional third spot on the tip of the tongue in alauda , calandrella , some certhilauda , eremophila , galerida , and lullula . after hatching , larks are covered with scanty down on their foreheads , napes , backs , shoulders , wings , and thighs .
5 . 9 in ( 15 cm ) ; male 0 . 7–1 . 2 oz ( 21–35 g ) ; female 1 . 1–1 . 2 oz ( 30–35 g ) ; smaller and more slender than skylark and crested lark . plumage buff brown , upperparts and chest streaked , distinguished from other larks by broad , white supercilium which continues to nape . black - and - white pattern of alula ( first digit of wing ) feathers very conspicuous . crown feathers can be raised to a small crest .
to attract a female and mark his reproductive territory , the male horned lark will engage in a
song flight
( cornell laboratory of ornithology , 2001 ) . he flies quickly up to eight hundred feet above the ground , and circles for several minutes . while circling , he sings . after hovering , he dives straight toward the ground with his wings closed . just before reaching the ground , he opens his wings , catches air and lands softly in his territory . these birds are monogamous .
the horned lark’s nest is a basket woven of fine grass or other plant materials and lined with finer material . two to four days after preparing the site , she begins weaving her nest from grass , small roots , shredded cornstalks , and other plant material , then lines it with down , fur , feathers , fine rootlets , even lint and string . the nest cavity diameter is about 3–4 inches ; the inside nest diameter is about 2 . 5 inches and its depth about 1 . 5 inches .
early european settlers named the magpie - lark after two groups of northern hemisphere birds that they were familiar with ; the magpies and the larks . however , they aren ' t actually like either of them . they are most closely related to a group of birds from the east coast of australia called the monarchs . magpie - larks are mostly seen foraging in pairs , however , outside of the breeding season , flocks of as many as a hundred or more birds may form in search of food sources .
lark has been providing pet sitting and dog walking services for us for many years ( i have two dogs and two cats ) . when i go out of town and she is staying in our home i know everything will be taken care of and when i return the house is the same as i left it and the animals are very happy . it is wonderful to leave with no guilt because i know lark loves them as much as i do . when she walks my dogs they come home tired and happy . i trust that she loves my four legged kids as much as i do and she shows it in the time and attention she gives them . and a final testiment to the love she has for my animals is that she was with me when we had to put our lab down two years ago . she loved him as much as i did and he needed her there at the end . you can ' t ask for better love and support of your four legged kids than that !
