The sea wasp
Australia is known for being home to some of the most dangerous animals in the world. This is especially the case with a jellyfish, also called “marine beetle”, “sea wasp”, “hand of death” or even “hand that kills”. It is simply the most poisonous jellyfish in the world.
When grown, the body of this box waterman can be the size of a watermelon. As for its 60 tentacles, they are about 4 m long and 6 mm thick.
It is found mainly in Queensland and the Northern Territory, where there are many busy beaches. It is also present off the coast of Southeast Asia.
If it does not intentionally attack bathers, the sea wasp can do great damage. Its jellyfish sting is extremely painful and its venom can kill a human in minutes. In Australia, 70 people are said to have died after being bitten. But these numbers would be underestimated.
The blue-ringed squid
Let’s stay in Australian waters. This is where an adorable squid lives about 15 cm, covered with bright blue rings. But do not be fooled by appearance … and above all, do not touch it! The lady is really extremely toxic. It is also the meaning of her rings, which only appear when she feels she is in danger.
This squid, which is one of the most dangerous sea creatures in the world, is one of the only ones capable of killing a human. Its poison, of salivary origin, contains a neurotoxin which acts in a few minutes and causes severe difficulty breathing. It is therefore necessary to go to the hospital immediately.

The black mamba
The black mamba is simply the most dangerous snake in the world. It is found only in Africa, mainly in the eastern and southern parts of the continent, in forested or rocky areas. It is one of the largest snakes on the continent, with a size that can exceed 4 meters. It is also the fastest snake in the world, which can move from 4.32 to 5.4 meters per second, or between 16 and 20 km / h.
When the black mamba lives during the day, it has a territorial behavior that can make it aggressive. He thus does not hesitate to bite several times if he feels in danger or that he wants to defend his territory. After inflicting a bite on its victim, it withdraws and lets the poison work. And beware of the consequences …
Its overwhelming toxin is composed of “dendrotoxin”, a neurotoxin that especially acts on the nervous system and very quickly causes paralysis of the respiratory muscles. The severity of the attack depends on the amount of poison injected. But 10 mg is enough to kill a grown man. Without prompt treatment, death is almost certain.

The stone fish
belonging to the family of Scorpaenidae, this 40 cm fish has a body devoid of dandruff, flaccid and bloated. It thus perfectly mimics the stones (hence the name) that make up its environment. But it has a weapon that is far more deadly than its camouflage: a very powerful poison that makes it the most poisonous fish in the world.
It is found along the Red Sea and the Indo-Pacific coast. It is therefore possible for a swimmer to step on it, and get a very bad surprise (the fish’s spines can even poke a hole in the sole of the shoe). In addition to severe pain, the neurotoxic toxin can sometimes lead to death.
Palestine’s yellow scorpion
From its scientific name Leiurus quinquestriatus, the yellow scorpion in Palestine also gets the nickname … the deadly prowler. The animal, which is yellow in color, measures about 90 mm and is found in Asia and Africa, in the desert areas. Its venom is extremely painful if stung, due to a mixture of potent neurotoxins. It can not kill a healthy man, but its sting can kill a child.

The ball fish
Buffer fish form a family of fish, also called “tetraodontidae”, or “buffer fish”. As their name suggests, these fish have the ability to inflate … like a balloon. This tactic serves to intimidate potential predators. But the majority of the fish in this family have a much more formidable weapon: an extremely powerful poison called “tetrodotoxin”. This is especially the case with fugu, which is traditionally made in Japan using a careful process to isolate the edible parts from the deadly parts located in the liver, ovaries and skin.
There is no antidote to this poison and about 20 g is enough to kill a human. The vital prognosis will therefore depend on the amount ingested as well as the health condition of the victim. The poison leads to muscle paralysis and eventually respiratory arrest. Death occurs in less than 24 hours.
The terrible filobat
Also called “Kokoï de Colombie”, the terrible phyllobate, from its scientific name “Phyllobates terribilis“, is a seed that is endemic to the Pacific coast of Colombia. With its small size (less than 5 cm) and its clear colors, this seed seems harmless. But it is not called” the terrible “for nothing. The glands located in its skin contain batracotoxins, which are among the most toxic substances in the world.
Skin contact can cause severe burns to the skin. And the risks are even greater if taken. Less than 200 micrograms in the bloodstream can kill a human.

The sea snake
If land snakes can be scary, we must not forget to be wary of sea snakes. hydrophiinae, they are in the vast majority much more venomous than terrestrial snakes. However, they are also less aggressive. When they bite, they do not necessarily inject venom.
One of the most poisonous species is called “Hydrophis belcheri“, or” Belcher’s Snake “or” Belcher’s Hydrophid “. The average lethal dose of its intramuscular venom is estimated to be between 0.07 and 0.25 mg / kg.
Quite rare, this snake with a yellowish to gray body is striped with black and measures less than 1 m. It lives in the Pacific Ocean, in the waters of the Philippines, Vietnam, Thailand, Indonesia, Papua New Guinea and the Solomon Islands.

The taipan of the desert
From its scientific name Oxyuranus microlepidotus, the desert taipei is up to 4 m long, which does not prevent it from being very fast. It is assessed by Guinness World Records as the most poisonous land snake in the world. By comparison, its venom is 25 times more toxic than that of the cobra. the toxins released by bite can kill 100 men in less than an hour. Fortunately, this species of snake, which is endemic to Australia, lives in the heart of the desert, and its contact with humans is rare.
The black widow is often considered to be the most dangerous spider in the world. And yet she is not the most formidable. This is Atrax robustus, a tarantula species that only lives around Sydney, Australia. Its highly toxic poison is especially dangerous to humans. With a size of about 5 cm, it is the males that are most to be feared. During the breeding season, they do not hesitate to enter homes in search of food. When they appreciate dark and cool places, they can take up residence in clothing.
If they feel in danger, they will not hesitate to bite. In case of bite, an anti-poison should be injected within an hour to avoid sequelae. A total of thirteen deaths have been attributed to this spider. However, since the creation of an anti-poison in 1981, only one death has been recorded.
