+'''Gastropoda''' is a large and diverse class of [[Mollusca|molluscs]], commonly known as snails and slugs. This class includes both aquatic and terrestrial species, and it is one of the most varied groups of animals in terms of form, habitat, and behavior.

+==Anatomy and Morphology==
-Gastropods are classified into subgroups based on characteristics such as shell structure, feeding habits, and reproduction. The three main subclasses are [[Prosobranchia]], [[Opisthobranchia]], and [[Pulmonata]].

+The head typically bears tentacles and eyes, which are used for sensory perception. The foot is a muscular structure used for locomotion. The visceral mass contains the internal organs, including the digestive, reproductive, and excretory systems.
-== Ecology ==
+==Habitat and Distribution==
-Gastropods play important roles in the ecosystem, serving as herbivores, detritivores, and predators. They are also hosts for a variety of parasites and are prey for many other animals.
+Gastropods are found in a wide variety of environments, from deep ocean floors to high mountain ranges. They inhabit marine, freshwater, and terrestrial ecosystems. Marine gastropods include species like [[sea snails]] and [[sea slugs]], while terrestrial gastropods include land snails and slugs.

-Humans interact with gastropods in a variety of ways. Some species are used as food, while others are kept as pets. Some gastropods are considered pests, as they can damage crops and gardens.

'''Gastropoda''' is a large taxonomic class within the phylum Mollusca. The class includes snails and slugs of all kinds and all sizes from microscopic to large. There are many thousands of species of sea snails and sea slugs, as well as freshwater snails, freshwater limpets, land snails and land slugs.

== Anatomy ==
The anatomy of a typical gastropod is divided into three parts: head-foot, visceral mass, and mantle. The head-foot comprises the head, which contains the mouth and sensory organs, and the foot, which is a muscular organ used for locomotion. The visceral mass contains the internal organs, and the mantle is a layer of tissue that covers the visceral mass and secretes the shell in those species that have one.

== Classification ==
Gastropods are classified into subgroups based on characteristics such as shell structure, feeding habits, and reproduction. The three main subclasses are [[Prosobranchia]], [[Opisthobranchia]], and [[Pulmonata]].

== Evolution ==
Gastropods have a long fossil record that goes back to the Late Cambrian. Over the years, they have evolved to adapt to a wide range of habitats, including marine, freshwater, and terrestrial environments.

== Ecology ==
Gastropods play important roles in the ecosystem, serving as herbivores, detritivores, and predators. They are also hosts for a variety of parasites and are prey for many other animals.

== Human Interaction ==
Humans interact with gastropods in a variety of ways. Some species are used as food, while others are kept as pets. Some gastropods are considered pests, as they can damage crops and gardens.
