Spotted coral blenny
I like blennies. They have the kind of goofy expression I see when I look in a mirror. The spotted coral blenny is considered large for the species, growing to 6 inches long. This one was engaged in typical blenny behavior, sitting motionless on a piece of coral.
In my attempts to identify what I see in the water, I use John P. Hoover’s book The Ultimate Guide to Hawaiian Reef Fishes, Sea Turtles, Dolphins, Whales, and Seals. His website is hawaiisfishes.com.
