Common NameSaw-scaled Viper
Animal ClassReptilia
DietSmall preys such as mammals, birds, lizards
HabitatDeserts, rainforests, semi-deserts, grasslands, dry and moist deciduous forests

The saw-scaled viper is a venomous snake found in many parts of the world, including Africa, Asia, and the Middle East. 

It is one of the most dangerous snakes in the world and is responsible for more human deaths than any other snake.

The saw-scaled viper gets its name from the saw-like markings on its body. It is a small snake, typically growing to only about 3 feet in length. However, its venom is highly potent and can kill a human within minutes.[1]

There are two main types of saw-scaled vipers: those that live in dry habitats, and those that live in wet habitats. 

The dry habitat snakes are more dangerous, as their venom is more potent.

Scientific NameCubozoa
Common NameBox Jellyfish
Animal ClassCubozoa
DietSmall fish, worms, fish, crustaceans, jellyfish
HabitatWarm coastal waters

The box jellyfish is a cnidarian found in tropical and subtropical waters. It is considered to be one of the most venomous animals in the world, and its sting can be fatal to humans. 

The jellyfish gets its name from its box-shaped body, which is composed of four main layers: the epidermis, the mesoglea, the gastrodermis, and the muscular system.

It has several tentacles that are covered in stinging cells called nematocysts. These stinging cells contain a venom that can cause severe pain and tissue damage. 

In some cases, the venom can even be fatal.

The box jellyfish is a predator that feeds on small fish and crustaceans, using venom to paralyze its prey so that it can be easily consumed. 

It is most commonly found in the Indo-Pacific region, but it has also been reported in the Caribbean Sea, the Gulf of Mexico, and even off the coast of Florida.

5. Funnel-Web Spider

Funnel-web Spiders
Scientific NameAtracidae
Common NameFunnel-web Spider

DietSpiders, small lizards, snails, ground-dwelling insects
Habitatunder rocks, decaying logs, crevices, rough-barked trees

The funnel-web spider is a species of venomous spider native to Australia. It is considered to be the most dangerous spider in the country, and its bite can cause serious illness or death in humans[3]

The spider is found in a variety of habitats but is most commonly seen in urban areas. It is a nocturnal creature, and often builds its web in dark, secluded places.

It is black and has a large, bulbous body. It is considered to be one of the most aggressive spiders and often attacks humans if it feels threatened. 

The funnel-web spider’s venom is highly toxic and can cause muscle spasms, paralysis, and death. It is responsible for several deaths each year in Australia, and its bite should always be treated as a medical emergency.

6. Inland Taipan

Inland Taipan
Scientific NameOxyuranus microlepidotus
Common NameInland Taipan
Animal ClassReptilia
DietSmall mammals like rats
HabitatSemi-arid regions of central east Australia

The Inland Taipan, also commonly known as the Western Taipan, is a venomous snake of the taipan genus, Oxyuranus. 

It is considered to be the most venomous snakes in the world in terms of LD50 and is often regarded as the most venomous land snake. The inland taipan is native to semi-arid regions of central Australia.

The inland taipan is a large snake, with an average length of 2.5 m (8.2 ft). The maximum recorded length is 3.6 m (11 ft 10 in). It is a slender snake with a small head and a narrow neck. 

The coloration of the inland taipan is variable, but generally, it is a light brown to olive green, with a darker cross-banding pattern.

The LD50 value for the inland taipan’s venom is 0.025 mg/kg. This means that 0.1 mg of inland taipan venom is enough to kill a human.

7. Platypus

Scientific NameOrnithorhynchus Anatinus
Common NamePlatypus
Animal ClassMammalia
DietLarvae, freshwater shrimps, crayfish
HabitatSlow-moving rivers, freshwater creeks, built water storages

Platypuses are one of the most venomous animals on Earth. Though they are often thought of as harmless, their venom can cause severe pain and even death. 

This animal is native to Australia and found in freshwater environments such as rivers and lakes. They are unique among mammals in that they lay eggs rather than give birth to live young.

Platypus is generally shy and reclusive but can be aggressive if provoked. Their venom is produced in a gland located near the base of their tail. 

When threatened, they will swing their tails at their attacker, injecting the venom through the sharp spurs on their hind legs. The venom contains a toxin that affects the nervous system, causing paralysis and sometimes death.

In humans, venom can cause severe pain, swelling, and tissue damage. If left untreated, it can lead to kidney failure and even death. 

There are no known antidotes for Platypus venom, so immediate medical attention is essential for anyone who has been stung.

8. Stonefish

Scientific NameSynanceia
Common NameStonefish
Animal ClassActinopterygii
DietReef fishes, marine invertebrates, other marine animals
HabitatCoral reefs, near or about rocks, sand

Stonefishes are one of the most venomous animals in the world. Found in warm coastal waters, these bottom-dwellers can deliver a painful and potentially deadly sting. 

They are well-camouflaged, blending in with the rocks and corals where they live. Their bodies are covered in sharp spines that inject venom when stepped on or brushed against.

While the venom of a stonefish is not usually fatal to humans, it can cause severe pain, swelling, and paralysis. Stonefish stings require immediate medical attention as they can be life-threatening. 

There are many different species of stonefish, all of which are equally venomous. The most common type is the Indian stonefish, which is found in the waters off of India and Australia.

If you are unfortunate enough to be stung by a stonefish, the first thing you should do is remove the spines from your skin. 

This can be done with a pair of tweezers or by gently rubbing the area with a credit card. Once the spines are removed, you should soak the affected area in hot water for at least 30 minutes. This will help to reduce the pain and swelling.

9. Cone Snail

Cone Snails
Scientific NameConidae
Common NameCone Snail
Animal ClassGastropods
DietWorms, other snails, small fish
HabitatShallo water near coral reefs

Cone Snails are one of the most venomous animals on Earth. They are found in tropical waters around the world and can grow up to 20 cm in length. 

Their venom contains a powerful neurotoxin that can cause paralysis and even death in humans. There have been several deaths reported from cone snail bites, so it is important to be aware of these creatures if you are swimming in their habitat.

Cone snails are carnivorous predators that hunt small fish and other invertebrates. They use their venom to subdue their prey before swallowing it whole. 

The venom is injected through a long, hollow tooth that the snail can extend from its mouth. This tooth can pierce through human skin, so it is important to be careful if you are handling a cone snail.

If you are ever bitten by a cone snail, it is important to seek medical help immediately. The venom can cause paralysis and respiratory failure, so it is vital to get treatment as soon as possible. 

There is no specific antidote for venom, but antivenom can be used to treat the symptoms.

What makes the cone snail’s venom so deadly? 

For starters, it contains a powerful neurotoxin that can cause paralysis and respiratory failure. 

What’s more, the venom is incredibly fast-acting, meaning that victims often don’t even have time to seek medical help before it’s too late.
