Lions are known to attack humans.
Various animals can and do attack humans. To reassure readers and promote conservation efforts, many sources claim that these animals only do so when they are hungry and nothing else is available, but this is not always the case. Animals that have been reported to attack humans for food include three of the four big cats (lion, tiger and leopard; jaguars are not known to eat people but will attack them if disturbed), the American black bear, the polar bear ( largest land predator in the world), wolves (especially the Gray Wolf), jackals, large crocodiles and crocodiles (especially the saltwater and Nile crocodile), large sharks (especially the great white shark, tiger shark and bull shark) and the Komodo Dragon.
The American black bear can see people as a source of food.
All of these animals have been around for millions of years, surviving hard times like the Ice Age. To survive in challenging conditions, predators must eat anything they can master, so evolution created these animals to be efficient killers. What’s more, predators exist at the top of the food chain, meaning they depend on a substantial supply of prey. When conditions get tough in a region, apex predators are usually the first to die because they are more likely to starve to death from being unable to find prey than the prey may starve from being unable to find its own food. , such as smaller prey or plants. All these forces optimize predators for aggression and feeding flexibility.
Wolves are known to attack people.
All cases where animals attack humans heavily depend on the species involved and the size of the humans. Jackals, for example, are small enough to attack only children, as trying to attack adults would likely be too difficult. Gray wolves, on the other hand, are larger and can attack humans for food, especially when they are hungry, as is amply documented in European folklore. Human fear of wolves led to massive extermination campaigns that wiped them out across much of their former range in Europe.
A Bengal tigress was responsible for over 400 deaths in India and Nepal before being shot in 1907.
Most bears only attack humans to protect their young (especially grizzly bears) or for territorial reasons, but predatory deaths have been reported, most often of the American black bear. Pepper spray is recommended as protection against these animals, although screaming is usually enough to scare them away.
The most lethal human predators are tigers and saltwater crocodiles. The Champawat tiger, a Bengal tigress shot in 1907, was responsible for over 400 documented deaths in Nepal and India before being shot by Jim Corbett. Rumor has it that a saltwater crocodile, Gustave, a 6 meter Nile crocodile that lives in Burundi, Africa, killed more than 300 people. While that number is exaggerated, the crocodile probably killed at least 100.
