Spotted porcupinefish

Diodon hystrix

HIGH
Family
Diodontidae
Also known as
Common porcupinefish, Spot-fin porcupinefish
Description
The spotted porcupinefish is a large, rotund fish covered in long, sharp spines and distinctive dark spots scattered across a pale tan-brown body. It possesses a beak-like fused jaw structure used to crush hard-shelled prey such as mollusks, sea urchins, and crustaceans. When threatened, it can inflate its body by swallowing water, erecting its spines as a defense mechanism.
Habitat
Found in tropical and subtropical seas worldwide, typically inhabiting coral reefs, seagrass beds, and rocky areas at depths of 2–50 meters. Common in the Indo-Pacific, Atlantic, and Eastern Pacific regions.
Conservation status
Least Concern
Notes
Excellent close-up macro shot showing fine detail of the spines, characteristic large blue-iridescent eye with amber iris, and dark spot patterning. The fish appears to be resting near the reef substrate. Species identification is confident based on the large scattered dark spots, long tri-rooted spines, and overall body morphology consistent with D. hystrix.
