Blennies are common inhabitant of tidepools and
reefs. They have elongate bodies with long dorsal and anal fins, blunt
foreheads, and small paired pelvic fins. Most are herbivorous, with comb-like teeth to graze
seaweed, while fang blennies with
large incisors feed by taking chunks of flesh from the unwary. Many species are small,
shy, or inhabit the surf zone.
