Taxonomy
editCaulophryne bacescui was first formally described in 1982 by the Romanian biologist Alina Mihai-Bardan from a single specimen taken from the Peru Trench in the Eastern Pacific Ocean off western South America.[2] This species is classified within the genus Caulophryne which is one of two genera within the family Caulophrynidae. The 5th edition of Fishes of the World classifies the Caulophrynidae within the suborder Ceratioidei of the order Lophiiformes, the anglerfishes.[3]
Etymology
editCaulophryne bacescui is a species within the genus Caulophryne, this name is a combination of caulis, which mean" stem", an allusion to the stem-like base of the illicium, with phryne, meaning "toad", a suffix commonly used in the names of anglerfish genera. Its use may date as far back as Aristotle and Cicero, who referred to anglerfishes as “fishing-frogs” and “sea-frogs,” respectively, possibly because of their resemblance to frogs and toads. The specific name honours the Romanian zoologist Mihai C. Băcescuof the Grigore Antipa National Museum of Natural History, who was a participant in the 1965 cruise on which the holotype was obtained. Băcescu gace guidance to Mihai-Bardan in the writing of her description.[4]
Description
editCaulophryne bacescui is known from a single specimen which has a standard length of 16.9 cm (6.7 in).[1] This speciemn was a metamorphosed, i.e. adult, female and differed from other species within Caulophryne by having no filaments on its illicium, having 46 teeth in its upper jaw, a similar number to C. polynema and by having relatively low ray counts in the dorsal and anal fins, 15 and 14 closest to C. pelagica.[5]
Distribution and habitat
editCaulophryne bacescui is known from a single specimen collected in the Peru Trench off the western coast of South Ameruca in 1965, it is a benthopelagic species which lives in trenches and abyssal habitats.[1]
