Triggerfish have a classic diamond shaped body. They are quite territorial fish, and have a retractable fin that is used as a warning to other fish that are in their area. When they are threatened, they find the closest hole in the coral, and wedge themselves in the space and using their retractable fin to prevent them being pulled out. Triggerfish like to eat crabs and other creatures hiding under rocks. In order to get to their food Triggerfish can shoot out a jet of water to flip over the rocks!!
