Physical Description
The body plan of the combtooth blennies is archetypal to all other blennioids; their blunt heads and eyes are large, with large continuous dorsal fins (which may have 3-17 spines). Their bodies are compressed, elongate and scaleless; the small, slender pelvic fins (which are absent in only two species) are situated before the enlarged pectoral fins, and the tail fin is rounded. As their name would suggest, combtooth blennies are noted for their comb-like teeth lining their jaws.
By far the largest species is the eel-like hairtail blenny at 53 centimetres in length; most other members of the family are much smaller. Combtooth blennies are active and often highly colourful, making them popular in the aquarium hobby.

Famous quotes containing the words physical and/or description:
“I was always a feminist, for I liked intellectual revolt as much as I disliked physical violence. On the whole, I think women have lost something precious, but have gained, immeasurably, by the passing of the old order.”
—Ellen Glasgow (1873–1945)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
