8 Aggressive Animal: Barracuda
In a contest between sharks and barracudas, even sharks that are fairly aggressive like the Great White, many fisherfolks give the barracuda an edge. Between 20 inches to 6.5 feet long, barracudas are both scavengers and ambush predators. Because of this, they may mistake a swimmer in their midst for a predator who has just had a meal and may be shedding bits of prey.
7 Aggressive Animal: Black mamba
Like most other animals, the black mamba does not seek confrontations with people, but when it is cornered it is notorious for its aggressiveness. It gets its name not so much from the color of its scales, which range from dark brown to gray, but for the color of the inside of its mouth when it gapes in a threat display.
6 Aggressive Animal: Chimpanzee
One reason that chimpanzees don’t kill or injure more humans than they do is that they are elusive and difficult to find in their natural habitat. Once thought peaceable, it became obvious to researchers such as Jane Goodall that chimps can behave with a nearly humanlike viciousness. In some sense, they lack a theory of mind, which means they can’t understand or empathize with their victims.
5. Aggressive Animal: African buffalo
Unlike the hippopotamus, the African buffalo’s huge, curved horns and robust, muscular body keeps humans from thinking it is cuddly. One of the big five of big game hunters, it has a reputation for both aggressiveness and what seems like vengeance. Only the lion and the biggest crocodiles think of it as potential prey. Unlike its Asian cousin the water buffalo, humans never domesticated the African buffalo.
4 Aggressive Animal: Horsefly
Like the mosquito, the female horsefly needs a blood meal in order to successfully reproduce. Unlike the female mosquito, the horsefly does not approach its victim tentatively nor is it easily dissuaded. Moreover, its bite is memorably painful. Biologists believe this is because the horsefly evolved to bite animals that couldn’t easily swat it away, so it didn’t bother to evolve an anesthetic in its saliva like the mosquito.
3 Aggressive Animal: Hippopotamus
People simply can’t believe that hippos are as aggressive as they are. Blubbery, herbivorous, seemingly lethargic, partially aquatic with incredibly cute babies, it is astonishing to learn that hippos kill at least 500 people every year. Found nearly everywhere in sub-Saharan Africa as well as along the Nile River, the hippo can move surprisingly fast on land. A determined hippo can sprint at 19 miles per hour.
2 Aggressive Animal: Fire ant
The fire ant gets the number two spot because it is one of the few animals that attack for what seems like no reason whatsoever. Social insects such as wasps or bees can be expected to defend their colony, but a fire ant that is simply patrolling around will crawl up on a barefoot and sting and bite for what seems like no other reason than the foot is in its way.
1 Aggressive Animal: Nile crocodile
The Nile crocodile gets the number one spot because it is the only animal on the list to consider humans a regular part of its diet. It’s just as likely to grab a human that strays too close to the water’s edge as it would a wildebeest. Hundreds of people are killed by the Nile crocodile every year.
