This bird wrasse is another of those fish that will grow up to look completely different than it did as a youngster. The juvenile above will not only change color, but will also end up with a much longer snout, like the fish on the right, a supermale.

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.
