Can you believe a snake has enough venom to kill several adults at once or that touching a small frog can take your life? Some of these creatures are beautiful as well as dangerous. Click the NEXT button to take a look at 15 of the most venomous creatures on Earth.

Belcher’s sea snake

One of the most poisonous snakes in the world, this marine reptile’s bite can kill a human being in under 30 minutes. Fortunately, it is relatively docile and doesn’t normally attack unless excessively provoked.

It can be found near coral reefs in the Indian Ocean and off the coasts of Thailand and the Philippines.

Redback spider

Generally found in Australia, these spiders carry a poison that causes serious harm and could be lethal if anti-venom isn’t given on time.

Most bites occur during the summer and are usually inflicted by female redbacks; they are more toxic, larger and live four times longer than a male.

Deathstalker scorpion

Deathstalker scorpions are aggressive arachnids that are found in North Africa and the Middle East. They are believed to be responsible for over 75 percent of scorpion-related deaths every year. Adults usually feel a sharp pain from the sting, whereas children may become paralyzed.

Brazilian wandering spider

The Brazilian wandering spider once held the Guinness World Record for being the most venomous animal in the world. An aggressive and dangerous creature, even a drop of its venom could prove fatal to a human being.

When the spider isn’t hunting or on the move, it hides in dark corners – inside houses, clothes and shoes and under log piles – which increases the chances of accidental discovery by human beings.

Box jellyfish

One of the world’s most venomous animals, the box jellyfish has killed over 5,500 people since 1954. Its venom attacks the heart, the nervous system and the skin cells.

This kind of jellyfish is found in coastal waters off Northern Australia and across the Indo-Pacific region.

Boomslang

A relatively shy snake, the boomslang doesn’t usually attack humans. However, when it does, the venom can be fatal. It contains an anti-coagulant – which prevents blood from clotting – that can lead to a slow and painful death. It is generally found in South Africa, Botswana, Mozambique, Namibia and Swaziland.

Blue-ringed octopus

Usually found hiding in the sandy bottom of tide pools and coral reefs in the Pacific Ocean, the blue-ringed octopus is one of the deadliest creatures in the world. It looks small but has enough venom to kill 25 people in a matter of minutes.

The venom attacks the nervous system, leading to paralysis and respiratory arrest. There is no known anti-venom but victims can be saved if artificial respiration is given immediately.

Carpet viper

There are several species of saw-scaled vipers, from the carpet vipers found in Africa to the saw-scaled vipers in the Indian subcontinent and Central Asia.

They are considered one of the deadliest creatures in the world and together account for most of the snake-related deaths in their habitats.

Their venom is slow-acting compared to other snakes’ but can cause organ loss if left untreated.

King cobra

The king cobra is believed to be the longest venomous snake in the world; its single bite has enough venom to kill around 20 people or an elephant in a few hours.

It can grow up to 17 feet (five meters) in length and is found across South and Southeast Asia.

Pufferfish

Pufferfish may look odd, but they are among the most poisonous vertebrates in the world.

Almost all varieties of this fish contain a poison called tetrodotoxin; the poison is lethal to most other fish but is particularly dangerous to human beings.

Tetrodotoxin is 1,200 times more poisonous than cyanide and there is no know antidote. That said, the pufferfish is eaten, but only when prepared by licensed chefs.

Cone snail

You may not regard snails as particularly poisonous creatures but the cone snail (also called cigarette snail) is a deadly creature.

Found in the reefs of the Indo-Pacific waters, they contain a venom called conotoxin, for which there is no known anti-venom.

Poison dart frog

Poison dart frogs are among the most beautifully-colored animals in the world; they come in vibrant shades of yellow, blue, green and red. They are, however, extremely poisonous.

A single golden poison frog (pictured), which is among the more lethal kind of dart frog, for example, has enough venom to kill 10 grown men.

Local tribes use the frog’s venom to lace their arrows. The poison is called batrachotoxin; it causes paralysis and death, even in small amounts.

Black mamba

Found in sub-Saharan Africa, black mambas (brown in color) are aggressive and fast-moving predators.

They have no qualms about attacking humans and can grow to 14 feet (four meters). Their venom can kill people within 20 minutes.

Stonefish

Regarded as one of the most poisonous fish in the world, stonefish are found all along the Australian coastline.

They usually live in shallow coastal waters, lying motionless and partly buried to attract their prey.

The poison can lead to muscle weakness, temporary paralysis and death, if not treated.

Inland taipan

The inland taipan’s venom (small-scaled snake) is regarded as one of the most toxic in the world.

Its venom has components of both neurotoxins and hemotoxins which causes gradual paralysis, difficulty in breathing and internal bleeding.

The snake is mostly found in the eastern parts of Australia. It is a relatively shy animal and there haven’t been many recorded fatalities.
