Barracuda
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.
Black Mamba
When it attacks, the mamba will bite and bite again and again, so the victim might have more than one set of toothmarks. The venom is a neurotoxin, and its effects are felt minutes after it’s delivered. If the person isn’t quickly treated with antivenin, they will die within seven to 15 hours as their cardiovascular system collapses.
Chimpanzee
The horror of chimpanzee attacks on humans is that they are intelligent enough to attack those areas of the human body that humans value, such as the face, the hands, or, in males at least, the genitals. Yet chimps, who are 1.3 to 1.5 times stronger than humans, are animal enough to be relentless.
African Buffalo
The African buffalo kills about 200 people a year, though it’s not as aggressive as the hippopotamus. The biggest buffaloes can be from 5.56 to a little over 11 feet long with a 2 to 3-foot-long tail and can weigh between 1100 and 2200 pounds.
Horsefly
The horsefly uses its Swiss Army knife-like mouthparts to slice open a wound and enlarge it. It then laps up the blood and adds anticoagulants to keep it from clotting. Because the bite is so painful, the horsefly will be quickly brushed away. In that case, it will either keep trying to come back or find another host. This is how the horsefly spreads diseases and parasites.
Hippopotamus
Their lower incisors and astonishing lower canine teeth also never stop growing, and they have been known to use this impressive weaponry to kill people. People are also overcome and trampled on land. Hippos are also fond of capsizing small boats and then attacking the people who fall into the water.
Fire Ant
While its sting may not be as hideously and lastingly painful as the sting of South America’s bullet ant, the fire ant comes by its name honestly. The pain of its sting feels like being pierced by a red-hot needle and lasts for some hours.
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.
