You must be surprised to read the name of the first deadliest animal. A human being is a social animal with a God-given power to think and rule the world. That is why it is superior to other living organisms. Unfortunately, humans have killed the most significant number of humans in history. They have been killing their mates for thousands of years. The world in this innovative era is still facing wars. Besides wars, we are decreasing the number of forests and eliminating greenery from the earth, resulting in global warming. Humans are also capturing the living areas of different animals that are not friendly to humans. The number of humans killed may not be more than that of animals, but humans are a significant cause of human and animal deaths on Earth.

2. Mosquito

Other than humans, mosquitoes are the deadliest animals, especially for human beings. Their bite is not so dangerous, even if it is not painful, but the parasites it transfers into the human body are the deadliest.

Lions and leopards are both very dangerous to humans. Most people have seen people petting lions. Though it is illegal to pet lions, people do not care about the law. According to reports, these animals kill 400 people a year. Though big cats are not human-friendly, they also find humans their enemies. Because they are territorial, they are conscious of their space and do not want something else to capture their territory. Both animals are carnivores and dislike eating anything other than meat. Their priority is to get the meat, no matter what animal it is.

4. Elephants

Meager numbers of people have seen elephants killing humans. It is because elephants are very gentle and human-friendly animals. They do not strike humans by killing means.

7. Kissing bugs


The Assassin bug is the collective name of multiple bugs. There is an organ in bugs known as a proboscis. Bugs use it as a tool to find the soft part of the mouth. That is why they are referred to as kissing bugs. Germs from a kissing bug can cause Chagas’ disease, which is fatal. Their bites are not painful, and bugs are not enemies of humans, but Chagas’ diseases can become fatal. Mortality rates are always meager if a person does not get proper treatment for Chagas disease. According to surveys, about 12,000 to 15,000 people dyes because of kissing bugs.

8. Hippopotamuses

Scorpions are the most threatening animals worldwide. Their stings are painful and take a while to cause swallowing and redness in the infected area.

A survey found that scorpion stings injure 1.2 million people and kill 3250 people yearly. Poison in the stings of a scorpion can cause heart attacks in people.

It is also surprising to hear a honeybee on the list of the deadliest animals. According to an estimate, honeybee stings kill 1,100 people yearly. A single honey cannot kill a human being, but a group of honey bees can collectively kill a human being.


Among the deadliest animals, humans stay at the top of the list. Being the deadliest animal does not depend on the animal’s size but on the severity of its aggression and the level of poison, it produces through venom. Some animals do not kill humans, but they are unaware that their strike can kill them.
