Reef Fish
Porcupinefish
Diodon hystrix · Bony fish, family Diodontidae (porcupinefishes); the spot-fin porcupinefish, largest of the family
By day a porcupinefish idles under ledges like a parked balloon with oversized, wet eyes: approachable, unhurried, and endearingly awkward, all of which reflects a defense budget spent elsewhere. The body is armored in spines that lie flat until the fish gulps water and inflates into a sphere too large and too spiky to swallow; its tissues can also carry tetrodotoxin. That armory frees it to be calm around divers. Night is the working shift, when it cruises sand and reef cracking urchins, crabs, and mollusks with fused, beak-like tooth plates. The spot-fin porcupinefish is the giant of the family and circles the tropics worldwide, turning up from Caribbean wrecks to Red Sea coral gardens. Never provoke inflation: the display costs the animal dearly, and a stressed fish can swallow air at the surface and die.

كيف تتصرف في حضوره
Approach slowly at eye level and enjoy the stare; never grab, chase, or pin one to trigger the balloon display.
الحفاظ على البيئة البحرية
Widespread and secure; some are dried and sold inflated as curios, a trade worth refusing.
