The most lethal sharks in the world that are inhabiting the waters of continents far and wide, spreading across the Atlantic and many other vast bodies of water must begin with the Great White Shark.
The meat on their bodies alone is dangerous and it cannot be consumed by humans because of its radical amounts of mercury. They range in size growing up to 20 ft while consuming approximately 11 tons of food per year. A Great White’s preferred meal is a seal lion in which they can eat as a whole without much effort.
The Great White Shark, whom needless to say, dominates the sea being the most unrivaled predatory fish. In terms of severity, only a few can compete with this voracious species of fish.
The Bull Shark and the Tiger Shark are the next closest that come head to head with the Great White. A Bull Shark’s advantage over many other predators in the sea is its ability to swim in not only salt water, but fresh water—the convenience of swimming in both types of water allows for a higher attack rate.
As for Tiger sharks, they are well-known for the stripes on their skin, and like a tiger in the wild human flesh is desired. Unlike the Great White they do not swim away after a couple of bites. Their sensory proficiency makes for great eyesight and smell to scope out their prey.
People are well aware of the seriousness in numbers of shark attacks per year. Worldwide there has been 50-70 attacks and counting each year. Many who live in Australia can report the mixed numbers of injuries to casualties from shark attacks infested along their shores.
Over a hundred different species of this fish roam the Australian marine life. There have been cases where attacks have ranged in only a 24 hour time span; a Great White and Bull being part of the attacks leading to intense and fatal injuries. Many along the coast of Australia during the summer-time have encountered induced life or death experiences due to the fact more people are swimming in deadly territory.
These deadly creatures will fight back—trying multiple times to attack their prey until they are successful. Whether or not they decide they want the taste of high fat contents or just demonstrating their territorial habitat, people and fish alike learn to evade such encounters.
