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.
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.
Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish, it is found in several other animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails).
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.

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.
They are the main predator of puffer fish along with other large fish, sea snakes, and humans. For humans, the ovaries and the liver must be avoided to prevent ingesting any poison (Diggles et al., 2003). [9] They use their color pattern as camouflage to hide from predators by blending into coral reefs and sandy bottoms.
The only other fish with which it might be confused is the long-spine porcupinefish, (Diodon holocanthus) but it has much shorter spines and it lacks a dark streak running between the eyes. [ 2 ] In case of danger, the porcupinefish can inflate itself by swallowing water to deter the potential predator with its larger volume and it can raise ...
