About this species

Chelonodontops patoca, also known as the milk-spotted pufferfish, milkspotted puffer, milkspotted toadfish, Gangetic blow fish, Gangetic pufferfish, or marbled toad, is a species of pufferfish in the family Tetraodontidae native to the Indo-Pacific. It ranges from East Africa to the Western Pacific from Korea in the north to northern Australia in the south. It is a tropical species that occurs in coastal waters, lagoons, estuaries, and rivers. While it does enter fresh water, the species does not occur more than a few kilometres from the sea. It is often seen in schools which sometimes enter freshwater streams. It is usually found at a depth range of 4 to 60 m and reaches 38 cm (15 in) standard length. The species is poisonous but reportedly considered a delicacy in Japan.
