Sharks are often perceived as dangerous predators due to their portrayal in popular media, but in reality, they are responsible for relatively few human fatalities each year. On the other hand, hippos are known to be quite aggressive and territorial, and they cause more human deaths annually than sharks.
According to available data, it's estimated that sharks are responsible for about 10 to 15 deaths per year worldwide. Most shark attacks on humans are not fatal, and many are cases of mistaken identity, where sharks bite humans but quickly release them.
On the other hand, hippos are responsible for a significant number of human fatalities each year in Africa. They may seem docile, but they are highly aggressive and have been known to attack boats and humans that come too close to their territory. It's estimated that hippos cause around 500 to 3,000 human deaths annually in Africa.
So, based on these statistics, hippos are responsible for more human deaths than sharks. However, it's important to note that both hippos and sharks are wild animals, and it's essential to exercise caution and respect their natural habitats to avoid dangerous encounters.
