Animals That Start With S

167 animals Animals and nature Checked 9 Oct 2026

Here are 167 animals that start with S, each with a one-line description so you can tell what it is. The best-known ones come first, then the full list in A to Z order.

S is the richest letter of all, with 167 animals. Snake, sheep, seal, spider and squirrel are some of the first animal words many children learn.

The sea is a huge theme. Look for compounds like sea lion, sea turtle, sea urchin, seahorse and sea anemone, plus starfish and stingray. Despite their names, the starfish is not a fish and the sea anemone is an animal rather than a flower. The snow leopard and snowy owl show another pattern, animals named for cold, white habitats.
