Definition The grey brotula (Bidenichthys consobrinus), also known as the orange cuskeel, is a rare species of viviparous brotula.
Overview This species is a member of the family Bythitidae (livebearing brotulas) within the order Ophidiiformes. It is primarily found in the marine waters surrounding northern New Zealand, where it inhabits rocky reef environments.
Etymology/Origin The genus name Bidenichthys is derived from a combination of the Latin bi (meaning "two"), the Greek dens or dentis (meaning "teeth"), and the Greek ichthys (meaning "fish").
Characteristics The grey brotula is documented as a rare species. It is found at depths ranging from approximately 30 to 178 meters, particularly within rocky reef habitats. As a member of the Bythitidae family, it is viviparous, a characteristic in which the species gives birth to live young rather than laying eggs.
