How are oysters born?
Oyster are hatched from eggs. An oyster spends all except the first few weeks of its life fastened to a rock or other hard object in the water. Along the world’s seashores there are many kinds of sea animals with shells to rocks and other hard objects in shallow water near the shore.
A baby oyster is hatched from an egg laid by the mother oyster. When first hatched, the baby oyster is about the size of a pinpoint and has no shell. Its shell begins to form when it is a day old. The baby oyster spends the first two weeks of its life swimming about freely.
Then it fastened itself so something hard, perhaps a rock or the piling of a wharf, or even to the shell of another oyster. It remains fastened to the same spot for the rest of its life, feeding on tiny plants and animals carried to it by the current.
The oyster grows about an inch a mouth until fully grown. Oysters are one of the most popular foods that we take from the sea. – Dick Rogers
