The juvenile Rockmover Wrasse (Novaculithys taeniourus), like many young wrasses, looks very different from its parents. However, both juveniles and adults move rocks to look for small invertebrates, which are then eaten. (Juvenile Rockmover wrasses are sometimes called Dragon Wrasses.)

This fish is hard to photograph since it darts around very quickly along the rocky bottom in shallow water. This one was photographed in about 20 feet of water off the south Kohala Coast near Puako Beach on the Big Island of Hawaii.
