Porcupinefish are known for their sharp spines and ability to "inflate." Porcupinefish will in water and blow their body up like a balloon. This act makes the porcupinefish look bigger and makes their sharp spines stick out all over their body, which lay flat when the fish is calm. Porcupinefish can be blue, brown, yellow, gray, and white. Their bellies are usually darker than their backs. They can be anyhwere from 10 inches (25 centimeters) to 12 inches (30 centimeters) long. Porcupinefish have two large teeth in the front of their mouths, one on the top and one on the bottom. The teeth stick out and gives the appearance of a beak.

Habitat

Porcupinefish are found in tropical waters in the Pacific, Indian, and Atlantic oceans. The majority of porcupinefish inhabit coral reefs.

Diet

Porcupinefish use their sharp front teeth to break the shells of shelled animals, like sea urchins and snails.

Predators

Dispite their spines, porcupinefish have to watch out for predators. Sharks and

large bony fish commonly feed on porcupinefish. Humans tend not to eat porcupinefish because the skin and meat has a toxin that is deadly to humans, but we still find uses for them. The people of pacific islands used porcupinefishs' skin as helmets, and in the Orient, they used the skin of a porcupinefish to make lanterns.
