Do snakes shed their skin?

Snake

A snake sheds its skin several times a year.  When a snake grows, its skin does not grow with its body.  Instead, the snake grows a new skin underneath the old one.  Eventually, the old skin becomes too tight, and needs to come off.

The snake begins to shed its old skin by rubbing its nose on a rock or a tree trunk in order to loosen the skin around its mouth.  Then, by crawling through rocks and brush, the snake manages to wriggle headfirst out of the old skin.  The skin frequently comes off whole, turned inside out.  This process is called molting.–Dick Rogers

How are oysters born?

Oyster

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
