The Birdbeak burrfish (Cyclichthys orbicularis) is a saltwater fish of the family Diodontidae that grows up to 30 cm.
Description
The birdbeak burrfish is a porcupinefish of the family Diodontidae reaching about 30 cm. Unlike many relatives it has short, three-rooted spines that are always erect and cannot be folded flat against the body. The brownish-yellow body bears dark blotches. With its jaws fused into a beak it crushes snails, shellfish, hermit crabs and sea urchins. When threatened it pumps itself up with water into a spiny ball, too large and prickly for most predators. The species lives near reefs, seagrass beds and rocky bottoms of shallow, warm coastal water in the Indian and western Pacific Oceans. Like many puffers and porcupinefishes its skin and organs may contain the poison tetrodotoxin; it should not be eaten.
