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]
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.

Synanceia is a genus of ray-finned fish belonging to the subfamily Synanceiinae, the stonefish, which is classified within the family Scorpaenidae, the scorpionfish and relatives. Stonefish are the most venomous fish known; stings can be fatal to humans. [2] [3] They are found in the coastal regions of the Indo-Pacific.
The tiger shark is considered to be one of the most dangerous sharks to humans. [1] Although it is found in the Red Sea it is not usually seen near reefs during the daytime. The Grey reef shark is territorial and may be aggressive, and has been involved in non-fatal attacks on divers.
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.
Chironex fleckeri, commonly known as the Australian box jelly, and nicknamed the sea wasp, is a species of extremely venomous box jellyfish found in coastal waters from northern Australia and New Guinea to Indonesia, Cambodia, Malaysia and Singapore, the Philippines and Vietnam. [1]
