Description

Randall's blenny is a combtooth blenny (Blenniidae) from shallow reef water of the western Pacific. The species grows to about 5 cm and has a slender, scaleless body with a blunt head, high-set eyes and often a fine colour pattern. With comb-like teeth it rasps algae and biofilm from coral and rock. As a lively bottom-dweller it darts in and out of holes and empty worm tubes. The fish is harmless to humans.
