Question

Where do sea shells come from

Answer 1

Sea shells are made by marine snails.  They produce a calcareous shell for protection.  As they grow, they lay down more shell.  When the snail dies, then the empty shell is left and is often washed up on shore by waves.

The different types of shells you find are made by different species of snails.

Answer 2

a seashell is the calcareous shell of a marine mollusk or similar marine organism.
