BUTTERFLYFISH - CHAETODONTIDAE
These popularly known reef fish are well adapted to live on a coral reef. Their narrow but high disc-shaped body allows them to swim through very narrow cracks and coral branches. Butterflyfish have a long snout with a small mouth which they use to feed on coral polyps, small crustaceans, worms, fish eggs and algae. The Chaetodontidae family mainly use their pectoral fins to swim long distances. Some species are territorial and live on a certain patch of reef which they protect against family members. Some species maintain lifetime relationships and always swim together with their partners. Other family members live in big schools. Mating occurs during sunset when the couple swim to the surface. The male pushes a few times against the females belly until the eggs come out and drift away with the current. After a few months the larvae will seek shelter somewhere on a reef and start their life as a juvenile butterflyfish. Many juvenile butterflyfish have a big ocellus on their back to mislead predators.
