indian goatfish

Parupeneus indicus

Have highly developed barbels which are really tongues that dig in the send and lick their prey to find them, then they dig them out to eat them.

Goatfish also change colour according to what they are doing and in ancient Rome goatfish were highly sought-after and expensive because the fish assumes a variety of colours and shades during death and for entertainment they would serve live fish and let them die before the eyes of the guests.
