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 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.
Species of puffer fish (the family Tetraodontidae) are the most poisonous in the world, and the second most poisonous vertebrate after the golden dart frog.The active substance, tetrodotoxin, found in the internal organs and sometimes also the skin, paralyzes the diaphragm muscles of human victims, who can die from suffocation.
A puffer's neurotoxin is not necessarily as toxic to other animals as it is to humans, and puffers are eaten routinely by some species of fish, such as lizardfish [15] and sharks. [ 16 ] Puffers are able to move their eyes independently, and many species can change the color or intensity of their patterns in response to environmental changes.
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.
A new study in the journal Frontiers in Toxicology found that microplastics in the fish we consume are far more widespread than you may think.. In late December, researchers from Portland State ...
These spinules are scattered around the puffer's body, but lie most concentrated on the puffer's abdomen. In addition to being a tough meal to swallow, the Caribbean sharp-nose puffer is a potentially lethal choice of prey due to the presence of dangerous toxins: Tetrodotoxin and Saxitoxin in the tissues of the puffer.
