Top 10 Most Deadly Animals






This is a list of the 10 most deadly animals found on land and in water. While some may seem innocuous – especially number 1, they lead to millions of deaths every year. From least, to worst, the list:
10. Poison Dart Frog
The backs of the poison dart frog ooze a slimy neurotoxin that is meant to keep predators away. Each frog produces enough of the toxin to kill 10 humans, though, strangely, in captivity, the frogs do not secrete this poison. The frogs are brilliantly coloured and live mainly in Central and South America. [Wikipedia Article]

9. Cape Buffalo
Cape buffalos weigh 1.5 tons and, when faced by danger, attack head on with razor sharp horns. They stand up to 1.7 metres high and 2.8 metres long. Humans are virtually its only predator and even lions will avoid crossing their path. Every year the Cape Buffalo is known to maul and kill multiple humans; some believe that it kills more humans in Africa every year than any other creature. [Wikipedia Article]
8. Polar Bear
These massive creatures, native to the Arctic, regularly eat elephant seals and could cut off a human head with one swipe of its paw. The Polar Bear is the most carnivorous of all the Bears and will eat walruses, whales, rheindeer, and even other polar beers. [Wikipeida Article]
7. Elephant
African Elephants, with their sharp tusks, are not as friendly as many believe. They kill over 500 people per year (either by stomping or impaling). The African Elephant generally weighs in at 16 tons. [Wikipedia Article]
6. Saltwater Crocodile
This is the largest of all living reptiles and is found mainly in Northern Australia and Southeast Asia. A healthy adult is typically 4.8 – 7 metres (15.75ft – 21ft) long, weighing up to 1.6 tons. There have been reports of larger. This creature is capable of killing and eating animals up tot he size of a water buffalo. In its most deadly attack (called the Death Roll) the crocodile grabs an animal or human with its mouth and begins to roll. A 1ton stallion is known to have been killed by this method in under 1 minute. In the water, the crocodile can move as fast as a dolphin. [Wikipedia Article]
5. African Lion
The African Lion can reach up to half a ton. Lions are thought to kill up to 70 humans per year in Tanzania. These large animals are eclipsed in size only slightly by the tiger. [Wikipedia Article]
4. Great White Shark
This shark is an exceptionally large shark found in coastal waters in all major oceans. It can reach lengths of up to 6 metres and can weigh up to 5 tons. The Great White Shark is the worlds largest known predatory fish. It is the only surviving species of its genus. In general these creatures do not attack humans, and (while there have been some fatalities) the majority of attacks on humans are believed to be test bites – the Great White Shark are known to test bite other objects in order to determine what they are. More people are killed each year in the US by dogs than Great White Sharks in the last 100 years. [Wikipedia Article]
3. Box Jellyfish
Also known as the wasp jellyfish, this salad-bowl sized jellyfish can have up to 60 tentacles as long as 15 feet. Each tentacle has enough toxin to kill 50 humans. They are found in Australia, the Philippines, and many other tropical areas. Since 1884 at least 5,567 deaths have been attributed to these creatures. [Wikipedia Article]
2. Asian Cobra
While the Asian cobra does not have the deadliest venom, it does make the most of what it has, causing the largest chunk of the 50 thousand deaths by snakebite per year. An average cobra is about 1 metre in length. [Wikipedia Article]
1. The Mosquito
Due to malaria carrying parasites transferred by the mosquito, it is responsible for the deaths of more than two million people per year. In addition, Mosquitos are estimated to transfer diseases to more than 70 million people per year. Even in countries such as the UK, New Zealand, and Japan, where the more temperate climate has reduced mosquito bites to mostly an annoyance, they still cause some deaths every year.

10 Amazing Hybrid Animals

Zebroid = Zebra + Equine

A zebroid (also zebra mule and zebrule) is the offspring of any cross between a zebra and any other equine: essentially, a zebra hybrid. In most cases, the sire is a zebra stallion. Offspring of a donkey sire and zebra mare, called a zebra hinny, do exist but are rare. Zebroids have been bred since the 19th century.The zebroid showed in the picture above, Eclyse, is a very unusual one, because of her coloring. With her über distinct makings, it's really hard not think she's a Photoshop mock-up.


Liger = Lion + Tiger

The liger is a hybrid cross between a male Panthera leo (lion), and a female Panthera tigris (Tiger) and is denoted scientifically as Panthera tigris × Panthera leo. A liger resembles a giant lion with diffused stripes. They are the largest cats in the world, although the Siberian Tiger is the largest pure sub-species. Like tigers, but unlike lions, ligers enjoy swimming. A similar hybrid, the offspring of a male tiger and a female lion is called a tigon.


Beefalo = Buffalo + Cow

What do you get when you cross a cow with a buffalo? The Beefalo, a hybrid animal that produces red meat lower in fat and cholesterol than beef. Most consumers have never heard of beefalo, let alone tasted it, and only a few Seattle grocery stores carry it.

How does a buffalo burger compare to a beef one? "It has a richer flavor and it's milder and sweeter than beef," says Ellensburg beefalo breeder Mark Merril, "and more juicy."

Cama = Camel + Llama

This hybrid animal, the product of breeding a llama and a camel, has been the only creature of this kind since her birth in 1995. Camas are humpless and have the long fluffy coat of a llama. Their ears are half way in length between camels and llamas, but they have the strong, desert-ready legs of a camel.


Leopon = Leopard + Lion

The Leopon is the result of breeding a male leopard with a female lion. The head of the animal is similar to that of a lion while the rest of the body carries similarities to leopards. The first documented leopon was bred at Kolhapur, India in 1910.


Savannah = Serval + Domestic Cat

The Savannah Cat is created by breeding an African Wild Cat, called a Serval and a domestic cat, usually an exotic looking domestic cat such as a Bengal, Oriental Shorthair, Egyptian Mau, or a Serengeti's. The offspring created by this combination are large domestic.


Grizzly Polar = Polar Bear + Brown Bear

Also known as Grolar Bear, this bear hybrid is a rare ursid hybrid that has occurred both in captivity and in the wild. In 2006, the occurrence of this hybrid in nature was confirmed by testing the DNA of a strange-looking bear that had been shot on Banks Island in the Canadian arctic.

A number of polar bear hybrids are described as Ursid hybrids, a term that designates any hybrid of two species within the Ursidae family. Polar bear hybrids with Grizzly bears have been reported and shot, but DNA techniques were not available to verify the bears' ancestry.


Toast of Botswana = Sheep + Goat

An unusual case of a sheep-goat hybrid was reported by veterinarians in Botswana in 2000, called the "Toast of Botswana". The animal was born naturally from the mating of a female goat with a male sheep that were kept together.

The hybrid was intermediate between the two parent species in type. It had a coarse outer coat, a woolly inner coat, long goat-like legs and a heavy sheep-like body. Although infertile, the hybrid had a very active libido, mounting both ewes and does when they were not in heat. This earned the hybrid the name Bemya or rapist. He was castrated when he was 10 months old because he was becoming a nuisance.


Blood parrot = Midas Cichild + Red Devil fish

The Blood parrot (also known as bloody parrot and blood parrotfish) is a hybrid cichlid. The fish was first created in Taiwan in around 1986. Its parentage is unknown, but the most commonly speculated pairings are midas cichlid with the redhead cichlid. This hybrid cichlid has various anatomical deformities, one of the most obvious, and also deadly, deformities is its mouth, which only has very narrow vertical opening. This makes blood parrot very hard to feed. Many die eventually because of this. Cichlid enthusiasts have called for their removal from the market and organized boycotts against pet stores that sell them.


Hybrid Pheasant = Golden + Amherst Pheasant

The Golden Pheasant has commonly been crossed with the similar Lady Amherst's Pheasant. The result is a hybrid with distinguished colors from its parents.
