The giant clam is a carnivorous invertebrate that can live over 100 years in the wild. They only get one chance to find themselves a habitat or home as once they fasten themselves to a spot on the reef, that is where they remain for their entire lives. Many are very colorful, often with blue-green, fluted mouths.
