FamilyDiodontidaeAlso known asSpotted porcupinefish, Common porcupinefishDescriptionThe porcupinefish is characterized by its large, prominent eyes with iridescent green pupils, a rounded body covered in sharp spines (modified scales), and small dark spots across its tan/brown body. It feeds primarily on hard-shelled invertebrates such as sea urchins, mollusks, and crustaceans, using its powerful beak-like fused teeth. When threatened, it can inflate its body with water to erect its spines as a defense mechanism.HabitatFound throughout tropical and subtropical seas worldwide, typically in coral reefs, rocky reefs, and seagrass beds at depths of 2–50 meters. Common in the Indo-Pacific, Atlantic, and Caribbean regions.Conservation statusLeast ConcernNotesExcellent close-up image showing the distinctive iridescent eye and visible spines. The fish appears relaxed and uninflated. The shallow spines and spot pattern are consistent with Diodon hystrix, though Diodon holocanthus (balloonfish) is similar; the relatively uniform small spots and longer spines favor D. hystrix.Creatures detected3 in frame- Porcupinefishfish
