After a few minutes I was able to get a view of this much of its head and body. Blennies are curious, territorial creatures and will follow a diver around the reef, hopping from perch to perch, perhaps hoping for a free meal from the disturbances created in the divers' wake.
Blennies are bottom-dwellers, swimming just far enough to arrive at the next perch on the reef.
Blennies look much like gobies, though gobies generally have more of a pointed or sloped head, and are from a different family classification, scientifically speaking. A good page listing the differences between blennies and gobies is maintained by the British Marine Life Study Society . Clinids are carnivorous, usually have a pointed nose, and have a long, multiple-spined dorsal fin. They usually have fringed tentacles, and some may grow to about 12 inches. The blenniids are small, blunt-nosed, scaleless blennies of warm and temperate seas.
