Molluskat

Molluskat, also known as mollusks, are a large and diverse group of invertebrate animals that inhabit a wide range of environments, from the deep ocean to freshwater streams and terrestrial habitats. They are characterized by their soft bodies, which are typically protected by a hard shell or other form of external protection. Mollusks are found in various forms, including gastropods, bivalves, and cephalopods.

Gastropods are a large class of mollusks that includes snails and slugs. They have a single shell, which is typically coiled in a spiral pattern. Bivalves, such as clams, oysters, and scallops, have two shells that are hinged together. Cephalopods, including octopuses, squid, and cuttlefish, have a complex body structure with a well-developed head and a set of arms or tentacles.

Mollusks play a significant role in various ecosystems. They serve as both prey and predators, contributing to the balance of marine and freshwater environments. Some species, like the giant clam, are filter feeders that help maintain water quality by removing particles from the water. Others, such as octopuses, are intelligent and adaptable predators.

The study of mollusks is an important field in biology, providing insights into evolution, ecology, and the diversity of life on Earth. Advances in genetic research have revealed that mollusks are closely related to annelids, another group of invertebrates, and together they form the phylum Mollusca. This relationship highlights the evolutionary connections between different groups of animals.
