Is a seashell an animal

Answer 1

Yes, in most cases seashells are formed by animals known as "mollusks". The mollusk category includes over 100,000 species of invertabrates, such as clams, scallops, oysters and snails--many of which produce the shells that often wash ashore after the animal has died.

Answer 2

It is not an animal it is the house or protection for some mollusks. They abandon them when they out grow them or continue to grow the shell until they complete the life cycle, then it is a discard again. Sometimes when the shell is discarded and becomes beached, it is again used by sand crabs as a home until they too need to discard it to find a larger shell. The shell is not an animal, the animal lives in it.
