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.

Takifugu in a tank. The fugu (河豚; 鰒; フグ) in Japanese, bogeo (복어; -魚) or bok (복) in Korean, and hétún (河豚; 河魨) in Standard Modern Chinese [a] is a pufferfish, normally of the genus Takifugu, Lagocephalus, or Sphoeroides, or a porcupinefish of the genus Diodon, or a dish prepared from these fish.
The long-spine porcupine fish is an omnivore that feeds on mollusks, sea urchins, hermit crabs, snails, and crabs during its active phase at night. [5] They use their beak combined with plates on the roof of their mouths to crush their prey such as mollusks and sea urchins that would otherwise be indigestible.
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.
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).
It is a euryhaline species that moves freely between freshwater and the sea. The natural diet of Colomesus psittacus is carnivorous and consists mainly of molluscs. [4] In the aquarium they eat a variety of invertebrates including snails, clams and shrimps. [3]
