🐟Bony-eared assfish

Acanthonus armatus Günther, 1878

The bony-eared assfish is a bathypelagic species of cusk-eel found in tropical and sub-tropical oceans at depths of from 1,171 to 4,415 metres. It has been found as far north as Queen Charlotte Sound off British Columbia's coast. This species grows to a length of 37.5 centimetres (14.8 in) standard length. The larvae are similar in overall form to the related gargoyle cusk, but have elongated 3rd, 4th, and 5th pectoral-fin rays.
