Tetraodon fluviatilis) is a species of pufferfish found in South and Southeast Asia.

Occasionally, algae and plant matter as well as fish scales and other ocean detritus is consumed.

The green pufferfish has a sharp front beak, allowing it to crush shellfish and crabs.

[citation needed] The green pufferfish grows up to a total length (TL) of 17 centimetres (6.7 in),[3] with a white underbelly and a metallic yellow or green top covered in black spots, bulging eyes which are metallic blue colour, and a very thick and broad forehead.

Its body usually has a leathery texture, but green pufferfish grown in captivity tend to have smoother skin.
