Porcupinefish are eaten as food fish and are an exotic delicacy in Cebu, Philippines, where they are called tagotongan. However, pufferfish can be dangerous to consume since they can cause tetrodotoxin poisoning.
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.
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.
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.
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.
Fugu prices rise in autumn and peak in winter, the best season, because they fatten to survive the cold. Live fish arrive at a restaurant, surviving in a large tank, usually prominently displayed. Prepared fugu is also often available in grocery stores, which must display official license documents. Whole fish may not be sold to the general public.
Pao suvattii, [2] or Arrowhead puffer, is a species of pufferfish. It is a medium-sized pufferfish, reaching 11.5 cm (4.5 in) SL. [3] It is also known as a Pignose Puffer or a Mekong Puffer. It is locally common in the Lower Mekong basin, and is exclusively a freshwater fish. [1]
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.
