They tend to reproduce from May to November. They are oviparous, meaning that they lay eggs. The females are known to lay their eggs in empty oyster shells. It is then up to the males to guard the eggs until they hatch. After they hatch, the free swimming larvae may migrate upstream and school over oyster reefs before settling. [5]

A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. Most seashells are made by mollusks, such as snails, clams, and oysters to protect their soft insides. [1] Empty seashells are often found washed up on beaches by beachcombers.
Shells contribute to more than 7 million tons of "nuisance waste" discarded every year by the seafood industry that mostly winds up thrown into landfills.
