Cyclichthys

Cyclichthys is a genus of fishes belonging to the family Diodontidae, commonly known as burrfishes or balloonfishes. These fishes are found in tropical and subtropical waters around the world. They are characterized by their ability to inflate their bodies with water or air when threatened, a defense mechanism that makes them appear larger and more difficult to swallow for predators.

The genus Cyclichthys is distinguished by its relatively short, stout spines that are fixed and not depressible. The body is typically covered in these prominent spines. Their diet consists primarily of hard-shelled invertebrates such as crustaceans and mollusks, which they crush with their strong beak-like jaws formed from fused teeth.

Several species are recognized within the Cyclichthys genus, each exhibiting subtle variations in spine arrangement, coloration, and geographic distribution. These fish are generally bottom-dwelling and inhabit coral reefs, seagrass beds, and other shallow-water environments. They are of minor commercial importance but are often encountered by divers and snorkelers due to their distinctive appearance and behavior. The conservation status of Cyclichthys species varies depending on the specific species and location, but generally they are not considered to be under immediate threat.
