perciform marinefish belonging to the family Labrisomidae. Found mostly in the tropical Atlantic andPacific Ocean , the family contains approximately 98 species in 14 genera.Stockier than the average blenny, labrisomids are elongate nonetheless; their dorsal fin spines outnumber soft rays (which may be absent altogether), and the
pelvic fin s are long and slender. Like many other blennies, labrisomids have whisker-like structures called "cirri" on the head and nape. Scales may be cycloid or absent in labrisomids; many species are brightly coloured. Thehairy blenny ("Labrisomus nuchipinnis") is the largest species at 23 centimeres in length; most are far smaller.Generally staying within shallow coastal regions to depths of c. 10 metres, labrisomids are
benthic fish spending most of their time on or near the bottom. Both sandy and rocky substrates are frequented, sometimes atreef s or amongst beds ofseagrass . Labrisomids are shy fish and will retreat into crevices if threatened.Crustacean s,gastropod s,brittle star s andsea urchin s make up much of the labrisomid diet.Two genera of labrisomid are noted for their
ovoviviparity ; "Xenomeda " and "Starksia " both retain eggs within theoviduct where they develop in safety. However, only "Starksia" species possess a gonopodium (a modified anal fin used as a copulatory organ).Genera
