Molluscs are a class of organisms often described as animals with soft bodies and no internal skeleton. They are classified in the phylum Invertebrates and include a variety of species, from sea mantises and snails to squids. Here are some common molluscs:
Gastropoda: This is the largest class of molluscs, including snails, conches, and gastropods. These animals usually have a shell, and their name "gastropods" come from the fact that their feet are located on the ventral surface of the body.
Cephalopoda: includes octopus, squid, cuttlefish and other animals. These animals usually have highly developed intelligence and complex behaviors, and they have well-developed antennae and complex eyes.
Bivalvia: This class of animals has two shells, such as clams and scallops.
Polyplacophora: This is a group of "multi-shelled" molluscs, such as sea cucumbers.
Scaphopoda: This is a group of marine molluscs commonly known as ivory snails.
Molluscs are found in marine, freshwater, and terrestrial environments and play an important role in biodiversity. Their body structures and behaviors are extremely diverse, making them important objects of biological research.
