The Macaronesian sharpnose puffer (Canthigaster capistrata) is a saltwater fish of the family Tetraodontidae that grows up to 9 cm.
Description
The Macaronesian sharpnose puffer is a small pufferfish of the family Tetraodontidae reaching about 9 cm. The stout body has a pointed snout with beak-like tooth plates and is brownish with blue lines and spots. Like other puffers it can inflate with water into a ball when threatened. It lives on shallow rocky shores of the eastern Atlantic around the Macaronesian islands, such as the Azores, Madeira and the Canaries, and along north-western Africa. As an omnivore it nibbles shellfish, worms, small invertebrates and algae. Its skin and organs contain the very strong toxin tetrodotoxin, making the fish deadly poisonous to eat, although it is harmless to touch.
