Nerites

Nerites are a family of small to medium-sized marine snails, belonging to the class Gastropoda. They are commonly found in shallow coastal waters, inhabiting a wide range of environments from rocky shores and coral reefs to mangrove swamps and seagrass beds. Nerites are characterized by their generally rounded or ovate shells, which are often brightly colored and patterned with intricate designs, making them popular among shell collectors.

These snails are herbivores, primarily feeding on algae that they graze from surfaces. They possess a radula, a ribbon-like structure with rows of tiny teeth, which they use to scrape food. Nerites are easily recognizable by their operculum, a hard, plate-like structure that seals the shell opening when the snail retracts inside. The shape and texture of the operculum can vary between species.

Nerites play an important role in their ecosystems by controlling algal growth. They are often found in abundance in suitable habitats. Some species are also harvested for food in certain regions, though their small size limits their commercial appeal. Reproduction in nerites typically involves external fertilization, with females laying gelatinous egg masses that attach to hard surfaces. The larval stage is planktonic, dispersing to new areas before settling and developing into juvenile snails.
