Just back from Turks and Caicos. Caught a Spotlight Goby (Gobiosoma louisae) eating a blenny or smaller goby. It snatched it off a sponge and worked to escape with it.
See the series of photos of it at my website link below..
Interested in comments.
The first photo shows the tail sticking out of the side of the goby's mouth. Later photos show the head sticking out.
