The masked puffer (Arothron diadematus) is a pufferfish in the family Tetraodontidae. It is found in Red Sea only. Maximum length 30 cm, olive-green/grey with a black mask over the eyes and pectoral fins, mouth has a black border. Usually solitary but schools during mating period. Some authors believe this to be a variation of the species Arothron nigropunctatus. Order: Tetraodontiformes, Family: Tetraodontidae, Genus: Arothron, Species: Arothron diadematus (Rüppell, 1829).
