The Titan Scorpionfish (Scorpaenopsis cacopsis), like other scorpionfish, has poisonous dorsal spines that are most dangerous when stepped on. The twenty-inch long Titan lies very still in caves and caverns, camouflaging itself both with its mottled appearance and its lack of movement. Popular as food, it has been over-fished and is now rarely found in Hawaii.

This one was photographed in about 40 feet of water off the south Kohala Coast near Puako Beach on the Big Island of Hawaii.
