Tridacnidae

The Tridacnidae family, commonly known as giant clams, are marine bivalve mollusks found in the Indian and Pacific oceans. These clams are notable for their immense size, with the largest species, Tridacna gigas, sometimes exceeding 500 pounds (227 kilograms) and reaching up to 1.2 meters (four feet) across.123

Giant clams are filter feeders, drawing water in through siphons to respire and capture food particles with their gills. They typically inhabit sandy or muddy bottoms, often buried just beneath the surface. While most bivalves have separate sexes, some members of the Tridacnidae family are hermaphroditic, possessing both male and female reproductive organs.24
