The pufferfish is one of the ocean's most captivatingly unique fish. It contains toxins that discourage predators from consuming them. They are also known for inflating their elastic bellies with water and sometimes air to achieve a larger, rounder shape as a defense mechanism.

Pufferfish are mainly found in the tropics and temperate zones. It is hard to find pufferfish living in cold waters like the Arctic Ocean. Here are a few fun facts about this cute but often deadly fish.

Fun Facts
