There are many types of coral but in these types of coral there is a whole world that has not been thoroughly explored.Many animals seek shelter,food,and areas to mate in this complex maze of tunnels, holes, and crevices . The coral reefs have many "renters" such as fish, lobster, and a extraordinary amount of animal life. There are over 500 types of fish living in major coral areas. These fish such as the Bluehead or the Spotted Butterfly Fish have brilliant colors for camouflage. The fish have extraordinary colors due to the multicolored coral in which the fish make their homes. The Clown fish is one of the well known fish that has bright colors. 

Many fish travel in packs to protect themselves from the many predators hiding in the coral caves. A few of these ever present predators are the infamous eels, Great White sharks, and including several types of sharks. These sharks have a hunger for the many small & large fish in the surrounding areas. These sharks include the Gray Tipped shark, and the many Blue sharks. The camouflage that the fish have adapted to using in coral reefs protect them from the deadly sharks. One type of fish the Scorpion Fish uses camoflauge for protection. A few fish such as the "Milk Fish" as the name was dubbed to it, for when the fish is squeezed or bitten it lets a milky substance from its skin that is annoying and distasteful to predators. Though the coral reef has many fish that are well defended and hidden predators still find food in the reefs. Several small types of fish who rely on speed for protection, soon learn that eels have also evolved to be quicker and more efficient hunters. Fish tend to live in crevices and only come out in groups or "schools" of fish because the more eyes the more likely a predator will be spotted and avoided than if 3 fish were in a group instead of 50 or 60.  Several animals that are not fish such as lobster and crabs live in coral reefs. The Flamingo Tongue Snail, the Red Coral shrimp,the Ghost Crabs, the Sand Shrimp and the Moon Snails all live in the coral. These animals also have bright colors like the other fish. A few other creatures that arent fish that live in the coral reefs are the White Sea Urchin , the Basket Starfish, and the Rock Crab all live in the coral reefs. Jellysifh also live in certain areas of coral reefs.
