Bathypterois dubius, the Mediterranean spiderfish, a lizardfish of the family Ipnopidae, is found in the Eastern Atlantic, as well as the Mediterranean and northwest Atlantic. It reaches a length of 20.5 centimetres (8.1 in) SL. Like other species in its family, the Mediterranean spiderfish is hermaphroditic. It is solitary in nature and feeds on mysids and copepods.[1]
The common name "Snoutlet crotchfeeler" was coined by D. E. McAllister in his 1990 book, A List of the Fishes of Canada.[2] McAllister created common names for deep-sea fish, which are unlikely to have day-to-day use, and they subsequently appeared in Encyclopedia of Canadian Fishes (1995) by Brian W. Coad.[3] In a review of Coad's book, Erling Holm criticized some of the deep-sea fish names coined by McAllister, like canopener smoothdream and doormat parkinglotfish, as "unnecessarily complex, easily misspelled, or downright silly" — and wrote that snoutlet crotchfeeler "violates the tenets of good taste".[4][5] Holm noted that many of the names coined by McAllister did not meet the criteria set by the Committee on Names of Fish.[4]
B. dubius inhabits the deep sea akin to its congeners, and has been observed at depths of 2,900 metres (9,500 ft) in the Eastern Mediterranean.[6] This habitat may be the reason why its eyes and pineal organs are significantly reduced, which has been compared to the blind cavefish, Typhlichthys subterraneus.[7] In contrast, they have well-developed lateral lines and "voluminous" areas of the brain associated with gustatory functions, which are connected to their pectoral fin rays which may house taste buds.[8] Typical of its genus, it is a sit-and-wait predator, "standing" on its elongated fins which form a tripod.[9] In commercial fishing operations the species is occasionally caught as bycatch,[10] but this may not have a significant impact on its populations, at least in the Northeast Atlantic.[11]
