According to a-z-animals.com, mosquitos are the deadliest animals in the world, killing an estimated 750,000 to 1 million humans yearly. With up to 110 trillion mosquitoes on the planet, the insects can carry lethal diseases like malaria, dengue fever, West Nile virus and Zika virus.
Humans: 475,000 people per year
Humans check in as the second-most deadly animal in terms of killing humans, thanks in no small part to gun violence.

Although humans can be attacked by many kinds of non-human animals, man-eaters are those that have incorporated human flesh into their usual diet and actively hunt and kill humans. Most reported cases of man-eaters have involved lions, tigers, leopards, polar bears, and large crocodilians.
Cardiovascular diseases are the leading cause of death globally. The second biggest cause are cancers.
No predators hunt lions to eat them; however, they do have a few natural enemies, such as hyenas and cheetahs. Hyenas compete with lions for food and often try to steal their kills.
Only four species, the great white shark, tiger shark, bull shark, and the oceanic whitetip shark, are known to occasionally attack humans, yet even when humans swim alongside these fearsome-looking behemoths they rarely attack.
#1 World's Scariest Animal: Nile Crocodile
All species of crocodiles attack approximately 1,000 worldwide annually, and about 40% of those attacks are fatal. The most aggressive crocodile is the Nile crocodile, which can be found throughout Africa.
The ocean quahog is a species of edible clam, a marine bivalve mollusk. Ocean quahogs live in the Atlantic and can live more than 400 years old. At 507 years of age, Ming the clam broke the Guinness World Record as the oldest animal in the world. Ming the clam was dredged off the coast of Iceland in 2006.
Ungainly as it is, the hippopotamus is the world's deadliest large land mammal, killing an estimated 500 people per year in Africa. Hippos are aggressive creatures, and they have very sharp teeth. And you would not want to get stuck under one; at up to 2,750kg they can crush a human to death.
What would it take to kill them all? A lot.
Its faster than a speeding bullet, its a Peregrine Falcon!
Yes, animals do practice revenge. Chimps do it, for example. Macaques do it, too, although not directly: if they cannot attack the offender because he is much stronger, they would hurt someone weaker instead, sometimes the attacker's relative.
The Javan rhino is the rarest large mammal on the planet, and none are in captivity, according to the World Wildlife Fund. They're a shy species used to living in dense tropical forests, which are tough to replicate in captivity, Mizejewski says.
#3: Chimpanzees
Chimpanzees are very smart animals and are able to solve many different problems posed to them by human trainers and experimenters. Our closest genetic relative comes in third place on this list of the most intelligent animals.
Pinnipeds (seals and sea lions) aren't the only marine mammals that have snacked on a shark. The sperm whale is a marine mammal that is considered an apex predator in certain habitats and it has been recorded as having eaten shark eggs.
