The Top 10 Incredible Animals That Live In Coral Reefs
Whale Sharks
Whale sharks are the largest fish in the world, growing up to 12 meters long. They are filter feeders, swimming forward to swallow prey such as krill, crab and fish larvae, small schooling fish, and jellyfish.
Despite having several hundred teeth, they do not use them to eat. Whale sharks are carnivorous and feed on plankton, small fish, and squid, and they are often found around coral reefs.
These gentle giants are known to inhabit both deep and shallow coastal waters and the lagoons of coral atolls and reefs. Whale sharks are docile creatures and often allow humans to swim around them, and some younger whale sharks have been observed to play with divers.
These creatures can live up to 100 years and are covered in a pattern of spots that is unique to each shark, much like human fingerprints. The coral spawning of the area’s Ningaloo Reef provides the whale shark with an abundant supply of plankton.
Sea Turtles
Sea turtles are an important part of the coral reef ecosystem, as they contribute to the overall health and resilience of coral reefs.
