Bean's bigscale is dark brown or black in colour, with a maximum length of 12.2 cm (4.8 in).

Its caudal peduncle (the tapered region behind the dorsal and anal fins where the caudal fin attaches to the body) is long.

[6] It has ridges of thin bones supporting deep mucous cavities on the head.

[8] Scopelogadus beanii feeds on amphipods, polychaetes, jellyfish and mysids.
