A snail is neither an insect nor an amphibian. Snails belong to the class Gastropoda, which is part of the phylum Mollusca. This means they are mollusks, not insects or amphibians.
Insects belong to the class Insecta and have characteristics like six legs, a three-part body (head, thorax, abdomen), and often wings. Amphibians, on the other hand, belong to the class Amphibia and include animals like frogs, toads, and salamanders. Amphibians typically have moist skin, live both in water and on land, and undergo metamorphosis from a larval stage to an adult.
Snails, being mollusks, have a soft body, often protected by a hard shell. They move using a muscular foot and are found in various environments, including land, freshwater, and marine habitats. So, while snails might share some habitats with insects and amphibians, they are distinctly different in their classification and biological characteristics.
