The mollusk family is a diverse group of creatures that includes clams, snails, squid, and octopuses. These animals are characterized by the presence of a soft body and a hard, protective shell. They are found in a variety of habitats, from the deep sea to freshwater lakes and streams. In scientific terms, the mollusk family is known as Mollusca, and this term is often used interchangeably with the word mollusk. However, there are other terms that can be used to refer to this family of animals, including gastropods, bivalves, and cephalopods. Each of these terms refers to a specific subgroup within the larger mollusk family and is useful for categorizing and studying these fascinating creatures.
