abudefduf also known as the sergeant-majors is a genus of fish in the family pomacentridae .

the name is from arabic abu , " the one with " ; and def , " side " , and the intensive plural ending - duf .

the name thus means " the one with prominent sides " .

now , i knew almost none of this before writing this piece . i’ve loved the name abudefduf saxatilis for decades , since i first encountered the sergeant major during a field course in jamaica – but i loved it for its sound , its rhythm , and the oddity of a “latin” name based on arabic . the duelling etymological theories and the story i’ve learned about peter forsskål and his doomed expedition to arabia felix add wonderful layers of history and personality to abudefduf , firmly cementing its place on my list of favourite names .

this species has been considered a synonym of abudefduf concolor , but a recent molecular study by lessios et al . ( 1995 ) confirmed that it is a separate species . it is closely related to a . concolor and is easily confused in the field during visual surveys . the distributions of the two species overlap between el salvador and costa rica , and a combination of morphological and genetic comparisons throughout the ranges of both species are needed to establish the full range of each .
abudefduf saxatilis is abundant in reef and rocky environments in the atlantic ocean ( molina et al . 2006 ) . populations have been recorded in the western atlantic ocean from as far north as canada to uruguay in south america at depths ranging from 0 to 20 m . a . saxatilis is abundant on caribbean reefs ( randall 1996 ) and on the tropical coast of western africa to angola where they form large feeding aggregations of up to a few hundred individuals . juveniles are found in tide pools or in protected areas schooling close to caves and shipwrecks . adults are most common on shallow reefs .
abudefduf saxatilis larvae have a reduced pelagic stage lasting 18 - 27 days and a post larval pelagic stage lasting 55 days ( molina et al . 2006 ) . the egg and larval development of laboratory - reared a . saxatilis has been exhaustively described by alshuth et al . ( 1998 ) . this study identified pigmentation , pelvic fin size , and the pectoral fin rays as the most useful characteristics for identifying the larvae of a . saxatilis from the yellowtail damselfish microspathodon chrysurus and beaugregory stegastes leucostictus . the sergeant major larva has a smaller and less pigmented fin and more heavily pigmented dorsal and pelvic fins .
this species is the most common and widespread species of damselfish in the atlantic . it is common off mexico in the gulf of mexico ( m . vega - cendejas pers . comm . 2013 ) . surveys found its abundance increased by 210 % in st . croix , 78 % in st . john , and 61 % in puerto rico from 2011 abundances ( noaa nccos 2010 ) . in the mamanguape environmental protection area in ne brazil , this species was one of the most abundant of fishes in the reef zones ( xavier et al . 2012 ) . abudefduf saxatilis comprised 1 . 7 % of all fish species in reef fish assemblages off havana city , cuba ( gonzalez - sanson and aguilar 2010 ) . in reef fish assemblages off northwest cuba , a . saxatilis accounts for 3 . 2 % of the total fish population and has a frequency of occurrence in the area of 66 . 7 % ( gonzalez - sanson et al . 2009 ) .

sergeant majors are oviparous . males prepare nests for egg masses on rocks , reef outcrops , shipwrecks , and pilings . spawning times vary depending upon region . for example , caribbean populations do not appear to exhibit a lunar spawning pattern . females in this region have been observed to spawn at various times throughout the month ( foster 2004 ) . during courtship males actively chase females in the early hours of the day and spawning takes place in the morning hours . approximately 200 , 000 salmon or red colored , oval shaped eggs measuring 0 . 5 to 0 . 9 mm in diameter are released in discrete , densely packed monolayers that adhere to the substratum ( robertson et al . 1993 ) . once fertilized the eggs turn greenish ( with 96 hours ) . the male guards the eggs until they hatch usually within 4 - 5 days after fertilization in the hour following sunset ( robertson et al . 1993 , foster 2004 ) .
temperature differences may account for regional variation in morphological traits , particularly size ( molina et al . 2006 ) .
the seargeant major feeds on an unusually wide variety of benthic algae , small crustaceans , colonial anemones , copepods , pelagic tunicates , invertebrate larvae , and small fishes ( randall 1996 ) .

. the sergeant major is a common damselfish of the tropical atlantic , often the first fish a new snorkeler or diver learns because it’s beautiful , abundant , and distinctive . like the hoopoe (
) , the sergeant major has a latin name that’s both fun to say and etymologically interesting . i was first drawn to the name because of its peculiar rhythm :
between genus and species , which arises because the species name is conventionally latin , while the genus name is arabic .

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 very restricted range and little is known about its population and life history characteristics . however , there are no major threats known . it is therefore listed as least concern .
this species was taken only in fatu hiva and nuku hiva within the marquesas islands , and henderson island and ducie atoll in the pitcairn group . although regions adjoining these islands have not been thoroughly sampled , it has not been encountered elsewhere in the tuamotu archipelago even though the area has been explored ( randall pers . comm . in gomon 2006 ) .
this is a large species , to about 315 mm sl . it inhabits coral reefs in depths of 13 - 74 m .
there are no known major threats to this species . it is possibly caught as bycatch .

occurs in shallow vegetated ( vallisernia ) areas where mouth brooding females hide among the weeds . herbivorous , feeding on plant material ( leaves of higher plants ) . territorial males clear a circular area among the weeds exposing the sand below , making a spawning site . known as
haplochromis similis
in the aquarium trade . max . size : 17 cm .
breeding males are characterized by a bright blue color with a reddish patch behind the gill plate . the anal fin is dark with an orange edge & has light - colored streaks . p . similis is often found in vallisneria beds where it feeds on these plants by biting out pieces of the leaves with the aid of its very sharp & closely packed teeth . males build cone bowers in the middle of these plant beds , where they have cleared room .

pronunciation : refer to our pronunciation key for an explanation of the phonetic symbols .
habitat : this is the primary location where the cichlid is found and is a generalization . this does not mean a fish cannot be found in other habitats .
diet : many cichlids specialize in eating one type of food ; notwithstanding , some of these specialized feeders are flexible and can be opportunistic feeders .
temperament : this describes the overall demeanor of a cichlid toward other tankmates that are of a different species . consider that there is variability in temperament due to various factors , including aquarium size , tankmates of similar appearance , stocking levels , and order of introduction . there may even be some variability among individual specimens .
conspecific temperament : this describes the overall demeanor of a cichlid toward other tank - mates of the same species . consider that there is variability in temperament due to such factors as aquarium size , stocking levels and order of introduction . there may even be some variability among individual specimens .
maximum size : this is in regards to total length ( including the tail ) of typical aquarium specimens . wild specimens may not attain this size , or may in fact grow larger than aquarium raised individuals due to various factors . also consider that this is the typical maximum size and there are exceptional individuals that will exceed it .
difficulty : this measure is a relative value , comparing a single species against all other cichlids . this only accounts for maintanence in the aquarium and not breeding considerations . 1 = easy and forgiving , 5 = extremely challenging .
this is a mild - mannered malawi cichlid that reaches a size of up to 15 cm . the female is silver with a black bar running laterally the length of her body . the male has a similar black bar that disappears almost entirely when he is sexually active . the male ' s colouring is irridescent blues and greens and can be very striking when he is in his full glory . in some texts this fish is referred to as a
red empress
but i think that this is a different species ,
at last ! i stumbled onto this fish about 2 years ago at petsmart ( of all places ) . they had no idea what he was . someone had just dropped him off . he is about 15 cm now and downright stunning . he almost never fights with the other tankmates . he tears around and displays his dominance , but never nips . he lives with a n . venustus of about the same size , an electric blue hap ( 10 cm ) , a red empress and an a . jacobfriebergi ( both about 3 . 5 cm ) . all in a 265 l . for a large male , he really is a puppydog .

type species type species sabella penicillus linnaeus 1767 as in fauchald , 1977 : 140 is incorrect for genus and date , but is derivative of the original name , serpula penicillus 1758 ) . knight - jones & perkins ( 1998 ) : 391 discuss whether the errors in spelling and authority in the designation by chenu ( 1859 ) are fatal to regarding that designation ( of sabella penicillus ) as the first type designation . they point out that as serpula penicillus ( as sabella ) is the only remaining taxon of those included by linnaeus ( 1767 ) it must be the only possible type .

a reference to montagu ( 1804 ) . also quoted by morch ( 1863 : 354 ) in a discussion on the status of the genus protula risso . hartman ( 1959 : 558 ) referred this name to protula sp . in serpulidae . however , amphitrite volutacornis montagu , 1804 belongs in the sabellid genus bispira . unless cuvier ' s name was available prior to montagu ' s it is difficult to see a relevance for
sabelle bispiralis
as a binomial under iczn code . it appears to be a gratuitous new name . [ details ]

the peacock worm ( also known as the fan worm ) ( 1 ) lives in a tough , membranous tube , which is covered in particles of mud ( 3 ) . this flexible tube may reach up to 10cm above the sand ( 2 ) . the head of the worm emerges from the tube in order to feed ; a beautiful crown of feathery tentacles banded with purple , brown or red ( 3 ) is extended during feeding ( 2 ) . the body of the worm , hidden by the tube , is greyish - purple or yellowish orange in colour ( 3 ) .
peacock worms often occur in large numbers . they provide habitats for other marine species , and may be found with sponges , seaweeds and ascidians ( sea squirts ) attached to them ( 3 ) . tiny hair - like structures on the tentacles known as ' cilia ' filter suspended particles from the water . these particles are then sorted according to size ; small ones are eaten , large ones are discarded and medium - sized particles are added to the top of the tube with mucus in order to increase its length ( 3 ) .
in this species , the sexes are separate ( some worms are ' hermaphroditic ' ) , and breeding takes place in spring and summer ( 3 ) . unlike the sedentary , attached adults , the larval stage is planktonic , drifting in the sea for a time before settling on the substrate ( 3 ) .
has a wide distribution and is common in many areas around the coastline of britain ( 2 ) . it is also widely distributed around the coasts of north - west europe ( 3 ) .
you can view distribution information for this species at the national biodiversity network atlas .
occurs on stones in mud and sand ( 2 ) on the lower shore and below ( 3 ) .
there may be further information about this species available via the national biodiversity network atlas .
