Porcupinefish

Diodon hystrix

HIGH
Family
Diodontidae
Also known as
Spotted porcupinefish, Common porcupinefish
Description
The porcupinefish is a large, round-bodied fish covered in dark spots and long spines that normally lie flat against the body but erect when the fish inflates itself as a defense mechanism. It has large, striking eyes and a beak-like fused dental plate used to crush hard-shelled invertebrates like mollusks, sea urchins, and crustaceans. It is typically a nocturnal feeder that rests in crevices or near the reef bottom during the day.
Habitat
Found circumtropically in tropical and subtropical marine waters, typically on coral reefs, rocky reefs, and sandy/rubble areas from shallow water down to about 50 meters depth.
Conservation status
Least Concern
Notes
The fish is resting on the sandy bottom under a reef overhang, a typical daytime behavior. Two small cleaner wrasse (likely Labroides dimidiatus) are visible near the dorsal area of the fish, suggesting a cleaning station interaction. Image quality is good with adequate lighting.
