Neritina [Neritina]

Description

Neritina, commonly known as freshwater nerites, comprises species that are primarily found in freshwater or brackish environments, but some are marine. These snails are known for their smooth, often vibrantly colored or patterned shells. They are small to medium-sized and have a distinctive operculum that seals off their shell opening. They play a role in controlling algae growth in their habitats.
