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.
The northern puffer, Sphoeroides maculatus, is a species in the family Tetraodontidae, or pufferfishes, found along the Atlantic coast of North America. [2] Unlike many other pufferfish species, the flesh of the northern puffer is not poisonous, although its viscera can contain poison, [1] [2] and high concentrations of toxins have been observed in the skin of Floridian populations.
Arothron mappa is a medium-sized fish which grows up to 65 cm length. [6] Its body is oval shape, spherical yet relatively elongated. The skin is not covered with scales, rather, the majority of the map puffer’s body is covered with small dermal spines with the exception of areas around the mouth, pectoral fin base, and caudal fin base.

The checkered puffer, Sphoeroides testudineus, is one of several fish species belonging to the family Tetradontidae, meaning "four teeth".Puffers have four tooth plates arranged in quadrants, with two teeth on the bottom and two on the top (Carpenter 2002).
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 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 ...
Whenever the puffer fish's swimming speed increases, its anterior ventral area is compressed with a pointed apex ventral to its pectoral fins. Regarding the change to this species' body in relation to its speed, Gordon, Plaut, & Kim [ 19 ] state that "at 2·0–2·5 BL -1 the fish increased the gape of the mouth widely enough to reveal their ...
