Possum Wrasses (genus Wetmorella)
by Scott W. Michael

These secretive wrasses are often overlooked by divers, except for those underwater explorers that spend time investigating the back of caves and deep crevices. This is the rarest member of the genus, Wetmorella triocellata, the pygmy possum wrasse. Photo by Scott W. Michael.

More experienced divers and underwater photographers are always looking for something new. If you are diving in the Indo-Pacific why not try locating a possum wrasse? These dainty, but secretive, members of the genus Wetmorella are usually seen in deep caves, under overhangs, or in the back of caves. In this Coral Realm feature article, we will look how and where to find these Lilliputians of the labrid family. We will also review what is known about their biology.
