Brotulotaenia brevicauda is a benthopelagic marine fish species in the family Ophidiidae. This totally black fish is usually found in the Atlantic Ocean but it has also been reported in the Indian.[2] B. brevicauda lives in deep water and grows up to 32 cm in length.[2][3][4] It is also occasionally known as the Short-tail cusk-eel.[1]

Description

B. brevicauda can be differentiated from other cusk eels in that it's operculum lacks a spine. [2] Many cusk-eels also have a patch of teeth in the middle of the basibranchial region, and while B. brevicauda lacks this feature, its gill-rakers form a number of tooth-bearing tubercules.[2] The otoliths of this species are also very small and rounded. [2]

In the rest of the skeleton, B. brevicauda scales are small, prickle-like, and are not imbricated. The dorsal fin lacks spines but has 79-84 rays. Similarly, the anal fin lacks spines but has 58-64 rays. In total this species has 63-66 vertebrae, 12-15 of which are in the pre-caudal region.[2]

Distribution and habitat

In the Eastern Atlantic Ocean, B. brevicauda is known from the waters near Portugal, as well as one record from an area northwest of Spain[5] as well as near the Azores.[6] In the Western Atlantic, it has been found near Bermuda, in the Gulf of Mexico and in the Caribbean sea, and may rarely appear near the Flemish Cap region.[2] B. brevicauda is also found in both the eastern and western Indian Oceans.[4]
