"Mollusks" Natural Recordings by Native Speakers
Mollusks are a group of invertebrate animals that have a soft, unsegmented body, typically protected by a shell. They are found in a wide range of aquatic environments, including oceans, rivers, and lakes, as well as on land. Mollusks include a variety of species, such as clams, mussels, oysters, snails, slugs, squids, octopuses, and nautiluses. They are characterized by their ability to secrete a hard, calcium carbonate-based shell, which provides protection from predators and helps to maintain their body shape.
Molluscoidea refers to a superorder of marine animals that includes snails, slugs, mussels, oysters, scallops, clams, mussels, and squids, among others. The term "Mollusca" is derived from the Latin word "mollis," meaning soft, due to the soft and unsegmented bodies of these organisms. This group is characterized by a distensible body, often protected by a shell, and a foot that is adapted for movement and grasping.
