Takifugu, also known by the Japanese name fugu (河豚, lit. "river pig"), is a genus of pufferfish with 25 species, most of which are native to salt and brackish waters of the northwest Pacific, but a few species are found in freshwater in Asia or more widely in the Indo-Pacific region.
The organs (e.g., liver) of the pufferfish can contain levels of tetrodotoxin sufficient to produce the described paralysis of the diaphragm and corresponding death due to respiratory failure. [51] Toxicity varies between species and at different seasons and geographic localities, and the flesh of many pufferfish may not be dangerously toxic. [5]
Takifugu rubripes, commonly known as the Japanese puffer, Japanese pufferfish, Tiger puffer, or torafugu (Japanese: 虎河豚), is a pufferfish in the genus Takifugu. It is distinguished by a very small genome that has been fully sequenced because of its use as a model species and is in widespread use as a reference in genomics.
Fugu contains lethal amounts of the poison tetrodotoxin in its organs, especially the liver, ovaries, eyes, and skin. [4] The poison, a sodium channel blocker, [5] paralyzes the muscles while the victim stays fully conscious; [6] the poisoned victim is unable to breathe and eventually dies from asphyxiation. [7] There is no known antidote for ...
Takifugu ocellatus, [1] sometimes known as the ocellated puffer or the orange-saddle puffer, is a species of anadromous pufferfish in the family Tetraodontidae. It is native to China and Vietnam . Juveniles of the species occur in brackish and freshwater environments, but adults are marine.
Tetraodontiformes (/ t ɛ t r ə. ɒ ˈ d ɒ n t ɪ f ɔːr m iː z /), also known as the Plectognathi, is an order of ray-finned fishes which includes the pufferfishes and related taxa. This order has been classified as a suborder of the order Perciformes, although recent studies have found that it, as the Tetraodontoidei, is a sister taxon to the anglerfish order Lophiiformes, called ...
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 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]
