ANIMAL SPECIES:Bean's Bigscale, Scopelogadus beanii (Günther, 1887)
Bean's Bigscale is a deepsea pelagic fish that has deep pits on its head. Its scales are easily removed so specimens that are caught in trawl nets are often badly damaged.
Identification
Bean's Bigscale is a moderately elongated fish with a large head that has deep mucous cavities and ridges of thin bones. It has a relatively long caudal peduncle and weakly attached cycloid scales. The scales are usually missing from fish that are caught in trawls. This leaves obvious scale pockets on the sides of the body.
Size range
The species grows to at least 12 cm in length.Distribution
Bean's Bigscale occurs in bathypelagic waters at depths from 800 m to 4000 m. It is known from the Indo-West Pacific and Atlantic Oceans.
In Australia it has been caught from off central to southern New South Wales.
