Blenniella gibbifrons, also known as the hump-headed blenny, bullethead rockskipper or picture rockskipper, is a species of combtooth blenny found in coral reefs in the Pacific and Indian Oceans from East Africa in the west to the Hawaiian, Line and Ducie Islands, in the east and north to Marcus Island.

[3][4] Blenniella gibbifrons inhabit the shallow water near the shore of intertidal reef flats.

They prefer water from 0.5 to 1.5 m deep where the substrate consists of a thin carpet of algal turf and sand.

They inhabit the water layer immediately above the bottom (benthic) .

Larvae are planktonic and often found swimming in shallow, coastal waters.
