Family: Gobiidae
Geography and Habitat: Blue dragon gobies live in the reefs of the western Indian Ocean a depths from 16 to 130 feet. However, they can be found all over the world in tropical waters. They often live inside the bodies or burrows of invertebrates. How they feed: The blue dragon goby feeds on small fish and plankton, often by hiding in burrows until their prey swims by and they can dart out to catch it. They also feed on coral by using their molars to crush the coral and extract beneficial calcium.
Body Form: The blue dragon goby can grow to be 1.5 inches in length. It has a long body and is a close relative of the shrimp. Swim Style: Its long dorsal fin allows it to move quickly upright through the ocean current. However, because of their bright colors and non-aggressiveness, gobies are important and easy prey for predators. Mouth Position: superior
