Oysters are found on the bottom throughout the Chesapeake Bay. Oysters have been around for 15 million years and in some places their fossil shells are 50 feet thick.
Oysters produce by spawning.
They spawn from June to September. Eggs hatch into larvae. Larvae develop into several stages. In one stage, the umbo stage, the little oyster has a foot that allows them to move around. The larvae swim in the water until they fall to the bottom to look for a place to attach.
