Yellow cuskeel
Dinematichthys iluocoeteoides

Family Bythitidae
updated Oct 2016
Where seen? This odd little eel-like fish is sometimes seen on some of our shores, usually near reefs at night. It was previously listed under Family Brotulidae and thus sometimes still referred to as brotulids. Another species, the Riau viviparous brotula (Ungusurculus riauensis) looks very similar.

Features: 4-7cm long. Long flattened body, small eyes on blunt rounded head. It is supposed to have barbels under its head, but this is hard to see this in a live fish in the wild. It has scales on body, cheeks and gill covers. The small tail fin is separated from the long dorsal and anal fins. These fishes are secretive. The eggs of these fishes develop inside the mother and she gives birth to live young (ovoviviparous).

Sometimes mistaken for other eel-like fishes. Here's more on how to tell apart sea snakes, eels and eel-like animals.
