The largest living mollusks on earth are the giant clams, which can grow up to four feet in length and weigh up to 440 pounds. These mollusks are found in tropical waters throughout the world, particularly in the Indo-Pacific region. They have an impressive lifespan of up to 100 years and can live in depths of up to 200 feet. The giant clam’s shells are made of two hinged plates, which open and close to capture food and provide protection from predators. The giant clam’s diet consists of plankton, which it filters from the water with its gills. The giant clam’s bright blue and yellow mantle is actually a symbiotic relationship between the mollusk and tiny algae, which the clam provides protection in exchange for nutrients. The giant clam is an important species in the ocean ecosystem and is considered a keystone species, meaning it provides essential services to the environment. Unfortunately, they are also one of the most threatened species due to overfishing, pollution, and the destruction of their habitat. Conservation efforts have been made to protect the giant clam and its habitat, in order to ensure its survival for future generations.
