Wart or fish stone master disguise


It is a genus of fishes. In it 110 species of fish. All treat the skorpenovy. As well as perches, fishes differ in shipasty back fins. Axes in them 13 — 15. Thorns are and on branchiate covers. In prickles — poison.

At a prick it gets to a wound together with slime with which gills and fins of a perch are covered. Toxin is carried on lymphatic system, causing lymphadenitis. This increase in lymph nodes. Such is reaction of immune system to poison.

In a prick place grouper thorns pain, hypostasis quickly develop. However toxin of fish is unstable, collapses alkalis, an ultraviolet and when heating. Poison of perches from the Barents Sea is especially weak. The Pacific individuals are most toxic. If poison is injected a little into one person, respiratory standstill is possible.

Arab surgeon

Represents family the hirurgovykh. It belongs to group the okuneobraznykh. Therefore poison of fish is similar to toxin of groupers, collapses under the influence of heat. However appearance of the surgeon is far from shape of relatives.

The body of fish is strongly flattened from sides, high. The tail fin of the surgeon has a half moon form. Coloring differs depending on a look. Most of surgeons motley, with bright strips and spots.

Again poisonous fishes

Again poisonous fishes accumulate saxitoxin. It not protein, but the alkaloid relating to purinovy connections. Poison contain a plankton dinoflagellit also many mollusks. They as it is supposed, receive toxin from monocelled seaweed, and those is from water, accumulating substance under certain conditions.


This family of fishes. His most poisonous representative — a dog. The alternative name — the fugue. Poisonous fish differs in the truncated body, a back and the wide head wide, flat from above with a klyuvoobrazny mouth.

In it there are 4 plates of the teeth which grew together between themselves. Them the fugue splits armors of crabs and a sink of mollusks. Eating the last, fish receives toxin. It is deadly, collects in a liver of a dog.

Despite virulence, the fugue eat. Training of fish, in particular, removal of a liver, caviar, skin is necessary. They are impregnated with poison. The dish is popular in Japan with what some excesses are connected.

So, in Gamagori, for example, the realization case by one of local supermarkets of 5 packings with integral fish is recorded. The liver and calves weren’t removed. It is enough toxin in each fish that 30 people died.

The photo of poisonous fishes often presents them in the exaggerated form. The dog becomes similar to a sphere at the time of a fright. The fugue involves water or air, depending on the stay environment. The increase in sizes has to frighten off predators. With people «focus» seldom takes place.

Sea eels

These poisonous fishes of the ocean choose tropical waters, reaching nearly 3 meters in length there. Sometimes eels eat mollusks which eat peridiniya. These are flagellates. The phenomenon of red inflow is connected with them.

Because of a congestion of crustaceans of water of the ocean become red. Thus many fishes perish, but eels adapted for poison. It is simply postponed in skin, bodies of moray eels.

Poisoning with meat of an eel is fraught with an itch, a sleep of feet, language, diarrhea and the complicated swallowing. Thus in a mouth smack of metal is felt. About 10% which poisoned will paralyze with the subsequent lethal outcome.
