Dichotomyctere ocellatus (syn. Tetraodon biocellatus), commonly the figure 8 puffer or eyespot puffer, is a pufferfish found in freshwater [clarification needed] in Southeast Asia. It is known from the lower reaches of the Mekong (Cambodia), the Peninsular Malaysia as well as Borneo ( Sarawak , Kalimantan ).
The grass puffer is often caught off beaches, docks, and piers using various baits such as worms, shrimp, sea lice, or cut fish. They are popular for children to catch and even popular as pets, but their intestines contain the extremely potent pufferfish poison tetrodotoxin which is potentially lethal to humans.

Tetraodontidae is a family of primarily marine and estuarine fish of the order Tetraodontiformes.The family includes many familiar species variously called pufferfish, puffers, balloonfish, blowfish, blowers, blowies, bubblefish, globefish, swellfish, toadfish, toadies, toadle, honey toads, sugar toads, and sea squab.

They are sometimes collectively called pufferfish, [3] not to be confused with the morphologically similar and closely related Tetraodontidae, which are more commonly given this name. They are found in shallow, temperate, and tropical seas worldwide.
Like other pufferfish, it can inflate itself with water or air. It forages for its preferred foods—molluscs and crustaceans—in sand and mud of the bottom sediment. Often an unwanted catch by anglers, the smooth toadfish is highly poisonous because of the tetrodotoxin present in its body, and eating it may result in death.
Tetraodon is a genus in the pufferfish family (Tetraodontidae) found in freshwater in Africa. It is the type genus of the family and historically included numerous other species; several Asian species were moved to the genera Dichotomyctere, Leiodon and Pao in 2013. [2] [3]
The toxin found in C. valentini as well as in other pufferfish species is one of the most potent naturally occurring toxins. [10] It is a neurotoxin called tetrodotoxin present in the skin and other tissues of C. valentini. It is lethal to many species of fish, thus making C. valentini unpalatable to predators. [11]
The reticulated pufferfish grows to a length of about 425 mm (17 in). The body is oblong and of flabby texture and is covered in short spines. The area between the eyes is broad and flat and the nostrils bear a small, solid branched tentacle. The lateral line is indistinct and bends sharply above the anal fin. Both dorsal and anal fins are ...
