The Atlantic Porcupine puffer, however, has an additional defense it is covered with sharp spines that stick straight out when the fish puffs out. What's more, this fish can grow up to three feet long.
Puffer fish hang around coral reefs, open sand and grassy flats, looking for food mostly.
This fish really likes to eat. The puffer comes well-equipped to find and eat food. Feelers hang down from their nostrils, helping them find food as they graze along the ocean floor. Even a hard shell can't protect a crustacean or mollusk unfortunate enough to end up inside a puffer's mouth. Bony upper and lower plates easily crush shellfish.
