Arionoidea

Arionoidea is a superfamily of air-breathing land pulmonate gastropod mollusks commonly known as round-backed slugs and round-backed snails. These species typically belong to the order Pulmonata, a clade of mollusks that are known for their shell-ossicles and other respiratory and pulmonary features.

This superfamily is widespread, with native species in temperate and tropical regions across the world. Arionoidea species exhibit a range of ecological adaptations.

Arionoidea is a superfamily of air-breathing land pulmonate gastropod mollusks. These species are commonly known as round-backed slugs and round-backed snails and typically belong to the order Pulmonata.

This superfamily is widespread, with native species in temperate and tropical regions across the world. Arionoidea species exhibit a range of ecological adaptations. Some species, such as the terrestrial pentrietoglobins, migrate with the rain, while others, like the hedgoggascín, have specific feeding habits.

Arionoidea species are primarily found in terrestrial environments, where they live on vegetation, leaf litter, and other moist areas. They lack shells, except for a few species that have small, protective coverings. These slugs and snails are primarily nocturnal, with most activity taking place at night.

The Arionoidea superfamily is characterized by the presence of a distinct carapace, which is typically rounded or flattened. Their eyes are simple and, in some species, few in number. The foot of the Arionoidea is flat, with a distinctive edge around the base, and the radula, a tongue-like organ, is used for feeding.

These mollusks breed and give birth to live young, many species have a complex reproductive biology which favors parthenogenesis, rather than traditional oviparity.
