Cyclichthys orbicularis, known commonly as the birdbeak burrfish among other vernacular names, is a species of marine fish in the family Diodontidae.
The Birdbeak burrfish is a medium size fish and can grow to be up to 30 cm (12 in) long.[1] It has a small mouth. This round fish is covered in short spines, each of which has a triangular base.[2] All of the spines on the top of the head have three subdermal roots.[3] It is pale brown above and white below and has round brown spots scattered across the body, especially towards the tail. The fins are translucent.[2]
Distribution and habitat
The Birdbeak burrfish is widespread throughout the tropical waters of the Indo-West Pacific region from Red Sea to the Philippines.[4] It is also one of the more common visitors to the waters around Cape Town in South Africa.[2] It is usually found on coastal shelves, occurring from the surface to a depth of around 150 m (490 ft). It most commonly occurs in areas where the sea floor is covered in a soft sediment, such as sand, but may also occur above reefs.[5]
