Giant clams are a type of mollusc. A significant proportion of the world’s molluscs call the Great Barrier Reef home.
Giant clams have a large, thick and unique shell that they close quickly if threatened by predators, an effective defense mechanism.
Interestingly, they have both male and female parts enabling them to produce and fertilise their own eggs.
Giant clams are filter-feedings, sucking water into their bodies and filtering food through their gills. Additional nutrients are gained from a symbiotic relationship with a tiny algae called zooxanthellae.
Some Giant clams found on the Great Barrier Reef are estimated to be around 120 years old.
