Gastropod
What is Gastropod?
Gastropods, commonly known as snails and slugs, are a class of mollusks characterized by a single, often spiraled, shell. They are found in a wide variety of habitats, from oceans and freshwater to terrestrial environments. Gastropods are known for their slow movement, using a muscular foot to glide along surfaces. They play a crucial role in ecosystems as herbivores, carnivores, and scavengers. Their shells, when fossilized, are often collected as gemstones.
