False Trevally


The Lactariidae family has only one genus and one species worldwide. The fish looks similar to members of the trevallies family but defers by not having detached spines in front of its anal fin, relatively deep caudal peduncle, without scutes on the lateral line, and the anal fin have more soft rays than dorsal fin.

False trevally is found in the Indo–West Pacific marine waters. It is an excellent food fish but is hard to find in the fish market nowadays, probably due to overfishing by trawling activities in the 1970's.
