The stonefish is the most venomous known fish in the world [16] and stings can cause death if not treated. [17] Most stonefish stings occur as a result of stepping on the creature which forces venom into the foot, while it is less common for the fish to sting when it is picked up. [18]
Venomous fish do not necessarily cause poisoning if they are eaten, as the digestive system often destroys the venom. [1] There are at least 1200 species of venomous fish, [2] [3] with catfishes alone possibly contributing 250–625 species to that total. [4] The former number accounts for two-thirds of the venomous vertebrate population. [5]
The reef stonefish is the most venomous fish in the world. [8] Its dorsal area is lined with 13 spines, each of which has two venom sacs. [8] The spines are sharp and stiff and have been known to pierce boot soles. [14] Stonefish venom can be fatal at a dose of only 18 mg, which the fish is capable of releasing with only six of its thirteen spines.
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.
It is sometimes called the most venomous fish in the world. There are at least 1,200 species of venomous fish, including: Stonefishes (Synanceia spp.) Lionfishes (Pterois spp.) Scorpionfishes; Toadfishes (Daector and Thalassophryne spp.) [14] Rabbitfishes (Siganus spp.) Goblinfishes (Glyptauchen panduratus and Inimicus spp.) Cockatoo waspfish ...
Synanceia horrida is, like other stonefishes, regarded as one of the most dangerous venomous fishes. Each fin spine has a fleshy cover at its base where there are two venom-producing glands. When the fish is disturbed, it erects its spines; if the fish is stepped on, the spines act like hypodermic syringes, injecting venom into the wounds.
Non-poisonous fugu can be produced by keeping the fish away from the bacteria that makes them poisonous. [10] Since October 2012, restaurants in Japan have been permitted to sell fugu that has been prepared and packaged by a licensed practitioner elsewhere. [30] China began issuing trial permits for serving fugu to restaurants in 2003.
