SEA Undersea

The wrasse family is huge, with around 500 species in all. They're also very diverse, ranging from tiny cleaners that may not get larger than two or three inches long, up to the giant Napoleon.

Six-Banded Wrasse

Also called: Sixbar Wrasse

Scientific name: Thalassoma hardwickei or Thalassoma hardwicke

The six-banded wrasse can be found in shallow reefs throughout the region. They are quite colorful, and can be quite curious. I had them in my face most of the time I was snorkeling one shallow reef in the Maldives.

Napoleon Wrasse

Also called: Humphead wrasse, Maori wrasse

Scientific name: Cheilinus undulatus

The humphead wrasse is the largest living member of the wrasse family. It has thick, fleshy lips and a hump that forms on its head above the eyes, becoming more prominent as the fish ages. Males range from a bright electric blue to green, a purplish blue, or a relatively dull blue/green. Juveniles and females are red-orange above, and red-orange to white below.

Moon Wrasse

Also called: Lunar Wrasse

Scientific name: Thalassoma lunare

This is definitely one of the more colorful wrasses. It's very similar to the Green Moon (aka Sunset Moon) Wrasse, which has a prominent blue streak at the edge of the pectoral fin. The Moon Wrasse is found on reefs throughout Southeast Asia.

Checkerboard Wrasse

Scientific name: Haliochoeres hortulanus

The checkerboard wrasse can be found in shallow reefs throughout the region. Females will have a white stripe behind the pectoral fin.

Bird Wrasse

Also called: Clubnosed Wrasse

Scientific name: Haliochoeres hortulanus

The bird wrasse - named for its bird-like nose - is found in shallow reefs throughout Southeast Asia. The male is colored dark blue-black, while the females are generally much lighter in color.
