trachipterus arcticus is a species of ribbonfish found predominantly in the north atlantic ocean , with one report from the mediterranean sea .

they are rarely encountered by humans due to their deep-sea habitat and the fact that they are of no commercial value .

this species is commonly referred to as the dealfish to differentiate it from the nine other ribbonfish species in the trachipteridae family .

the species commonly known as red bandfish ( cepola macrophthalma ) is sometimes referred to as ribbonfish , but it is unrelated to any ribbonfish in the trachipteridae family .

description : hello , a few years ago i was on a holiday with my parents and we ' ve seen a fish wash ashore ( but it was stil alive ) in the meditteranean which i think , based on the information on your site , is trachipterus arcticus . you can check the details here : urltoken ( if it is in dutch you can change the language in the upper right corner ) . on your website you say that there is only one report of this species from the mediterranean , so when my id is correct it will be the second i guess ? can you confirm the id as trachipterus arcticus ? thanks in advance and sorry for my bad english , best regards , jonas pottier , belgium .

the deal fish ( trachipterus arcticus ) is a real beauty . the slim and flat body shines like silver , and the red fins look like decorative feathers . this fish is a rare sight as it lives in deep waters ( 300 - 600 meters ) . sometimes dead deal fish get washed ashore . this fish has not the same elegance on land , especially when it has bee dead for some days .

dealfish are found in the north atlantic to as far south as florida . not much is known but they are about them . they feed on small fishes and squids .
the bottom picture recently surfaced . . . i jest . the fish washed up on the beach in florida . it has been misidentifed by some as an oarfish . it is not . there is another close relative of this fish that lives around australia and other places that is very similiar . it also goes by the name dealfish . but the scientific name is different . same genus name different species name .
vågmären har stjärtfenan käckt i topp som ingen annan svensk fisk . eftersom den dessutom är långsmal och silvrig med röda fenor är den lätt att känna igen . totallängd 300 cm , vanligtvis 100 cm . en mycket långsträckt art vars rygg är mer rundad än buksidan , så att den liknar ett utdraget pilblad . huvudet är litet och trubbigt , ögonen relativt stora och tänderna mycket korta . ryggfenan börjar strax bakom ögat och fortsätter bakåt nästan till stjärtfenans bas . de främre 5 - 6 fenstrålarna är avgränsade från resten av ryggfenan samt något förlängda jämfört med de omedelbart påföljande , men hela fenan är relativt lång . analfena saknas . nedre stjärtfensloben är kort , medan den övre stjärtfensloben är välutvecklad och uppåtriktad , vilket ger stjärten är säreget utseende . bröstfenorna är mycket korta och rundade . bukfenorna är trådlika hos unga individer och saknas helt eller är starkt förkortade hos vuxna individer . fjäll saknas , utom i sidolinjen - som löper rakt från huvudet bakåt till stjärtfenan - där de ser ut som små taggar . längs bukkanten finns en rad spetsiga små knölar . kroppen är silverglänsande med 1 - 5 svarta fläckar som försvinner med ökande ålder . ryggfenan och stjärtfenan är illröda , bröstfenorna rosa . fenstrålar och fjäll : d iv - viii . ca 150 , a saknas , p 10 - 13 , v 0 ( 4 - 6 hos yngel ) . fjäll saknas utom i sidolinjen , där de är svårräknade .
vågmär förekommer regelbundet men sällsynt i skagerrak , och emellanåt påträffas den även i kattegatt och öresund . totalt har omkring 20 fynd gjorts i sverige , senast i bohuslän 2011 . arten har en omfattande utbredning över hela nordatlanten mellan ungefär 30° n och islands , grönlands och nordnorges kuster .
vågmär är en nordatlantisk art med förekomst från madeira till island och norra norge . arten lever pelagiskt och oftast på stort djup . den uppträder regelbundet men relativt fåtaligt i nordsjön och mera regelbundet på djupt vatten utanför norges kust . vågmären är en sällsynt besökare längs svenska västkusten med fynd från bohuslän till öresund .
vågmär är en pelagisk fisk som uppehåller sig på relativt djupt vatten , ned till 600 meters djup , och lever av fiskar och bläckfiskar . den blir könsmogen vid 14 års ålder och 245 cm längd . en hona kan producera ca 580 000 ägg , och såväl äggen som larverna är pelagiska .

i det avancerade verktyget kan man söka ut och få fram artlistor , t ex arter i ett visst län , i en viss biotop , substrat , som påverkas av en hotfaktor , eller som är knutna till en sk värdart , t ex trädet alm . dessa kan även kombineras .
söka fram arter som är rödlistade , knutna till alm , är beroende av död ved och som finns i kronobergs län .
söka fram arter som är rödlistade , lever i småvatten och som påverkas negativt av igenväxning .
defaultläget i verktyget är arter som är rödlistade 2015 och dessa är klassade på samtliga sökfaktorer . under fliken rödlistekategori kan man dock välja att även inkludera arter som inte är rödlistade . om man väljer att inkludera icke rödlistade arter behöver man vara medveten om att samtliga arter inte är klassade på samtliga faktorer . nedan en sammanställning av vad som är komplett .
denna funktion används när du vill skapa din egen lista av arter att hantera . du kan t . ex . navigera mellan arterna i listan genom att klicka på deras namn . du kan också välja att använda knappen ”jämför arter” för att se bilder , kartor och kännetecken i en jämförelsevy .
du kan komponera ditt eget urval av arter genom att klicka dig fram via släktträdet och där välja arter eller artgrupper till din lista . ett annat sätt att göra ditt urval är att använda fliken ”filtrera” , där du kan söka på olika egenskaper . ovanför listan med sökresultatet finns en knapp ”lägg i mitt urval” .

some of the most common fish in the ocean are the small pelagic fish , which means they spend their life away from the coast and near the surface . in warm waters anchovies and sardines are superabundant while in cold waters , it´s herrings and smelts ( incl . capelin ) . in between , one can find blue whitings , and mackerels . these species are not many but they are extremely abundant and migrate great distances . changes in their distribution due to environmental changes are dramatic and easily noticeable . usually they feed on zooplankton such as copepods .
) arrive on the coast in the spring and summer . adult herring is often found in great abundance off the northern coast and in fact sustained the most important fisheries there for decades . however , the migration patterns of the adult herring can change dramatically , so large herring has not been particularily common off northern iceland during the last decades . adult capelin remain outside the fjord except during the spawn in the late winter , at which time they move closer to the coast and follow it to the south shore . some capelin remain in the various fjords along the north and east .
some larger pelagic fish are occasionally found off northern iceland . however , large pelagic fishes are rare in cold waters , and their role is taken over by
) . all are rare guests but for some unknown reason really many dealfish were found within the fjords in 2009 . although dealfish are related to opahs , the two species are radically different in appearance . the opah is nearly as tall as it is long and it‘s thick and heavy , reaching a weight of 270 kg . it is also brightly colored . the opah was recently shown to be warm - blooded . on the other hand , the dealfish is very long and slender . it can reach a length of 300 cm and its body is a silvery white on the sides with bright red fins .
the smallest pelagic fish are usually found at middle depths . three of these are often seen off the northern coast are the

the ribbonfish are any lampriform fishes in the family trachipteridae . these pelagic fish are named for their slim , ribbon - like appearance . they are rarely seen alive , as they typically live in deep waters , though are not bottom feeders . the sparidae are
it is believed to be two different stocks of dela fish : one in the northeastern atlantic and another in the northwestern atlantic .
a norwegian trawler got a lot of dela fish while trawling for blue whiting west of ireland in march 2007 . scientists on board said that they never before had got so many deal fish on such a survey . the deal fish can grow to be three meters long .
the steward on the vessel prepared some deal fish for the crew . reliable reports tells that the deal fish didn’t taste much . it had a jelly - like consistency and the crew left the dinner table early that day . maybe the conclusion had been different with a steward and a crew from asia ?
a couple of strange fish caught with trawl in the northern atlantic ocean has been shown on this post . her are two more of these strange looking creatures . the fish above looks like a monster thought it has the seize of a small herring . it seems to be able to eat preys of its own seize with its gigantic gap . the long and sharp teeth makes this fish look more than dangerous . i do not know the names of this fish , nor the name to the fish below .
something like an eel with a tale and a birds head ? the appearance is not important while living in total darkness on several hundred meters depth . below you see a photo of its head .

balbaroo fangaroo is an extinct species of kangaroo .

it was discovered at the riversleigh world heritage area in northern australia and described as a new species in 2000 .

the species was described from fossilized remains of part of the skull .

the skull is approximately the size of that of a modern wallaby .

the curved upper canine teeth are more than twice as long as the adjacent incisors and form " fangs " which may have been visible on the living animal even when its mouth was closed .

this feature is reflected in the fossil 's nickname , " fangaroo " , which later became part of its official scientific name .

balbaroo fangaroo

skull of balbaroo fangaroo , a member of the fanged kangaroos that may have been in direct competition with cookeroo hortusensis .
the two species , cookeroo bulwidarri and the cookeroo hortusensis were very small animals that moved on all fours , and outlasted a competitor species the balbaroo fangaroo .
the fanged species , named the balbaroo fangaroo , might not have been as good at adapting to the environment change from the rainforest to the open woodland , the researchers suggested .
belongs to balbaroo according to l . r . s . schwartz and d . megirian 2004
the newly found genus was in direct competition with a rival kangaroo species living in the same place at the same time – but the rival species had fangs . the ancient kangaroos outlived this fanged species , named the balbaroo fangaroo , because it was more able to adapt to the environment . bones of the balbaroo is pictutred
a new species of fanged kangaroo has been described from 15 - 13 million year old sites at the riversleigh world heritage area , but it seems to represent one of the last living members of the fanged kangaroo family , balbaridae . the study published in plos one , reviews all species in the genus balbaroo , which contains the famous fanged kangaroo , balbaroo fangaroo . the new species , named balbaroo nalima , has a partial skeleton associated with its skull , providing some information about the locomotion of the animal . it appears that fanged kangaroos were mostly walking on four legs , and probably galloped rather than hopped .

researchers have discovered two new species of extinct , tiny , non - hopping kangaroos that could help uncover the evolutionary story of modern kangaroos and wallabies .
the genus was discovered after an analysis of ancient fossil deposits at the riversleigh world heritage area in north - west queensland , and is thought to be between 15 and 23 million years old .
a team of researchers at the university of queensland , the university of new south wales , and the western australian museum published a paper last week officially describing the new genus .
university of queensland researcher and lead author of the publication kaylene butler said the discovery highlights evidence that the cookeroo are a direct ancestor of the kangaroos and wallabies that exist today .
what is really interesting about this new species , and the family they belong to , is that they represent the ancestors of our modern kangaroos and wallabies ,
ms butler said .
what ' s happened is at some point [ competitor ] kangaroos have gone extinct , while the descendants of cookeroo , and the other kangaroos that are closely related to it , have diversified and increased in numbers .
so what we ' re trying to understand is … how they were able to survive and increase in numbers at the same time that the fanged [ competitor ] kangaroos went extinct .
the new genus was named in honour of queensland museum researcher dr bernard cooke , who led research into the ancestry of ancient kangaroo fossils at riversleigh .

the fanged kangaroo have no descendants today , and appear to go extinct sometimes in the middle to late miocene ( around 10 million years ago ) . they were a very diverse family , with many species , and ranged in size from 3 - 10kg .

skull of cookeroo hortusensis , a new species of ancient kangaroo from the riversleigh world heritage area .
two newly described species of tiny kangaroos that lived between 18 million and 23 million years ago scurried rather than hopped , a new study finds . but although these pint - size kangas were short on bounce , they outperformed their fanged kangaroo relatives , which lived alongside them and eventually went extinct , researchers say .
in a recent study , researchers described a new kangaroo genus , cookeroo , and two new species : cookeroo bulwidarri , dated to about 23 million years ago , and cookeroo hortusensis , which lived between 18 million and 20 million years ago .
both species were found at the riversleigh world heritage area in northwestern queensland , australia , a location recognized as one of the richest fossil deposits in the world , according to the united nations educational , scientific and cultural organization ( unesco ) world heritage center . [ see photos of kangaroos , wallabies & other cute marsupials ]
according to kaylene butler , the study ' s lead author , the new genus occupies a position near the base of the kangaroo family tree that includes all modern kangaroos and wallabies , their close relatives . butler , a paleontologist at the school of earth sciences at the university of queensland in australia , told live science in an email that the team figured out where to place cookeroo by comparing 119 different features representing 69 kangaroo species .
cookeroo is distinguished as a genus by the combination of a number of features on the skull and teeth
— points of comparison that were also used to distinguish between the two new species , butler said .
the newfound minikangaroos are
the size of very small wallabies ,
with bodies that probably measured about 17 to 20 inches ( 42 to 52 centimeters ) long , butler said . the landscape at the time was very different from the arid outback it is today , butler said . c . bulwidarri and c . hortusensis likely inhabited a dense forest , moving through it on all fours and sharing it with a diverse collection of animals : marsupial moles , feather - tailed possums , ancient koalas and crocodiles .
cookeroo also lived alongside other species of small kangaroos that were part of the ancestral group for kangas alive today , as well as a related group of fanged kangaroos , butler told live science . the fanged kangaroos were also plant eaters , and they probably competed with the ancestors of modern kangaroos over their habitat ' s vegetation .
however , the fanged kangaroos went extinct , while the ancestors of modern kangaroos continued to diversify and thrive ,
butler said .
the direct competition between the two groups may have contributed to the fanged kangaroos ' extinction , butler suggested in a statement , though it is not certain what features provided cookeroo with the advantage .
the fossil record for kangaroos is quite rich ,
butler said .
we have giant kangaroos from the pleistocene [ 2 . 6 million to 11 , 700 years ago ] and pliocene [ 5 . 3 million to 2 . 6 million years ago ] , as well as other sites similar in age to riversleigh where we see our tiny ancestors of modern kangaroos as well as the fanged kangaroos .
however , there is still much to learn about kangaroo evolution , and new fossil finds help to bring this ancient lineage more clearly into focus , butler said .
hopefully , further study of these new species will help us understand just what is so special about the ancestors of modern kangaroos — why did they survive when , at the same time , the fanged kangaroos went extinct .
the findings were published online feb . 17 in the journal of vertebrate paleontology .

david attenborough has called riversleigh one of the four most important fossil deposits in the world . originally a cattle station , the site gained world heritage listing in 1994 because of the amazing fossils found there .
“riversleigh itself has at least 300 individual fossil deposits and we continue to find a mass of new sites every year . the fossil deposits range in age from approximately 25 million years old to about 30 , 000 years old , ” says palaeontologist dr karen black from the university of new south wales ( unsw ) .
here , the combination of calcium carbonate , phosphates , and a rainforest full of animals has led to 25 million years of pristine and highly detailed fossils .

“anything that landed in that water was guaranteed to become a fossil , because almost immediately limestone began to precipitate around the object . . . it could have been a leaf , we ' ve even found butterfly wings , ” says professor michael archer , also from unsw , who has been digging fossils at the site for over 35 years .

the snail eater is the newest weird animal found at riversleigh . it’s distantly related to marsupial carnivores , but has a weird premolar which scientists think it used to crush up snails .
“it wasn ' t until we found the tooth that was part of a mammal jaw that we realised what it was , and how strange it was . there ' s no other mammal in the world that has teeth like this , ” says archer .
“it is speculation , but its informed speculation , based in part… [ by ] actual study of the teeth itself , that lead us to the conclusion that it is primarily a snail eater . ”

“the giant platypus was far bigger than any known platypus and at around 80cm to 1m in length . it also differs to the living platypus in that it has well developed teeth – whereas those of the modern species are poorly developed and absent in adult individuals , ” says black .
there were a wide variety of platypuses 25 million years ago - a far cry from the one lone species we see in rivers today .

“the carnivorous kangaroo was something that shocked us when we first found them . we didn ' t believe it , but we couldn ' t come to any other conclusion , ” says archer .
“there was a whole group of these [ types of kangaroos ] that would have stood up to about a human shoulder with teeth that show unmistakably that they are eating flesh and bone . ”
these types of species would have made their home in lush rainforests , not open plains like today’s kangaroos .

these crocodiles could grow up to 5 metres in length , and the first skull found at riversleigh was discovered with the bones of a marsupial lion in its mouth .
although this species may not have been able to climb trees , some other species like mekosuchus whitehunterensis , which were goanna - like , may have been able to climb , possibly to eat bird eggs .

these guys aren’t actually related to lions , but they are still the largest meat - eating mammal known to have existed in australia .
“riversleigh 20 - 15 million years ago was a biodiversity hotspot because of the palaeoenvironment of temperate rainforest with rain all year round , ” black explains .
“the diversity of plants in the riversleigh rainforests was able to support a high diversity of mammals . mammals at this time were occupying niches no longer seen in the much drier environments of australia today . ”
sponges are thought to be some of the earliest animals to have evolved on earth , and this one is a true giant .
native australian animals such as bats and rodents don ' t get enough attention - which puts them at risk , according to a new study .

the iconic hop of modern - day kangaroos make the species instantly recognisable , and a firm favourite among children .
but 23 million years ago , an ancient relative of these marsupials scurried through dense forests on four legs , instead of two .
this wallaby - sized kangaroo also outlived another species of fanged marsupial that lived alongside it because it was better at adapting to their changing environment .
ancient bones ( skull pictured ) belonging to two species of the new kangaroo genus were found in queensland . the genus has been named cookeroo , in honour of researcher dr bernard cooke , who led much of the research program focused on the evolution of riversleigh ' s ancient kangaroos
ancient bones belonging to two species of the new kangaroo genus were found in the riversleigh world heritage site in queensland , australia by researchers at the university of queensland .
the genus has been named cookeroo , in honour of researcher dr bernard cooke , who led much of the research program focused on the evolution of riversleigh ' s ancient kangaroos .
and the two new species within the genus are cookeroo bulwidarri , which lived about 23 million years ago , and cookeroo hortusensis , which lived 18 to 20 million years ago .

the first was named after the word bulwidarri which means ' white ' in the aboriginal waanyi language , referring to the riversleigh white hunter site where specimens were found .
the second was named after the latin word hortusensis , meaning ' belonging to the garden ' in reference to neville ' s garden site at riversleigh , where the bones were found .
the new species of kangaroo couldn ' t hop like modern - day kangaroos ( stock image pictured ) but it is thought to be an ancestor of all wallabies and kangaroos alive today . the tiny marsupial was the size of a wallaby and lived between 15 and 23 million years ago
the newly discovered non - hopping ancestors of modern kangaroos were in the same place as fanged kangaroos at the same time .
but one group , the fanged kangaroos , went extinct while the ancestors of modern kangaroos survived .
the non - hopping ancestors appear to have won and outlived the fanged species .
the fanged species might not have been as good at adapting to the environment change from the rainforest to the open woodland , the researchers suggested .
' they moved on all fours , scurrying across a densely forested landscape quite different from the dry outback we see in western queensland today , ' kaylene butler , graduate student at the universiy of queensland who worked on the paper , said .
the newly found genus was in direct competition with a rival kangaroo species living in the same place at the same time – but the rival species had fangs .
' we also know that both the fanged kangaroos and the ancestors of modern kangaroos were plant eaters .
' surprisingly fangs have nothing to do with diet but the molar teeth tell us both were likely herbivores .
' so we know they were likely to be competing for the same resources and clearly the ancestors of modern kangaroos appear to have won .
' exactly why the ancestors of modern kangaroos survived while fanged kangaroos went extinct requires further study , ' she added .
the first genus was named after the word bulwidarri which means ' white ' in the aboriginal waanyi language , referring to the riversleigh white hunter site where specimens were found ( marked ) . the second was named after the latin word hortusensis , meaning ' belonging to the garden ' in reference to neville ' s garden site
after uncovering the bones , the researchers were able to identify the new genus and two species within the genus by looking at the skull bones and teeth and comparing them to known species .
' currently we are unsure as to exactly what makes these non hopping ancestors of modern kangaroos so special .
' trying to determine what makes these animals better adapted is where our research is headed in the future , ' butler told mailonline .
