Combtooth blennyBlenniidae

Combtooth blennies (Blenniidae) are small, often benthic fishes found on coral reefs and rocky shores. Most species have a slender, elongated body, typically scale-less, with a prominent, blunt head and large eyes set high. A single, continuous dorsal fin extends along their back. Most species range from 5 to 10 cm (2 to 4 in) in length. Their common name refers to the distinctive row of comb-like teeth, which they use to scrape algae and small invertebrates from rock and coral surfaces. Coloration varies widely among species, from mottled browns and tans for camouflage to bright yellows, oranges, and greens.

They inhabit shallow coastal waters and rubble zones, typically from the intertidal zone down to 40 metres (130 ft). Blennies commonly perch motionless on hard substrates or within small crevices. While primarily herbivorous, their diet also includes small invertebrates. Some species are known to mimic other fish in colour and pattern, potentially gaining protection from predators. These blennies are commonly observed across almost all shallow 🌊 Red Sea habitats.
