Scorpion fish lie in wait for food to swim by. When the prey is close enough the scorpion fish extends its mouth and sucks the prey in. They usually are the color of their surroundings, have irregular shaped extensions around their chins and are nestled in the reef thus are very difficult to spot. For defense they have lethal poisons in their dorsal fins. Their camouflage is so good and their defense so powerful they don't need to move.
Scorpion fish are related to Stonefish and Lionfish
