The great white shark is a species of great mackerel shark renowned for its daunting size, with some growing up to 20 feet in length, but most being much smaller, with females averaging 15 to 16 feet and males that they tend to be between 11 and 13 feet. Able to live to be 70 years or more, these apex predators can swim at speeds of up to 16 mph for short bursts and are one of the ocean’s deadliest hunters. But there is another species of colossal monsters that inhabit the depths of the ocean and have puzzled scientists for years.
Resembling a huge piece of weather-beaten rock, the Greenland shark can grow up to 24 feet in length, making it one of the largest in the Arctic and one of the largest of all fish.
But this is about their confrontation with the great white.
Their top speed is lethargic 1
Studies in the Arctic have revealed some bits of information about Greenland sharks, but because they live in deep, cold waters, humans rarely get a glimpse.
They only come close to the surface in places where shallow water is freezing enough for them, mainly around Greenland and Iceland.
As a result, they have long been considered purely polar animals, as well as the Pacific sleeper shark and the southern sleeper shark.
But they have been reported on the coasts of Canada, Portugal, France, Scotland and Scandinavia, so scientists believe they may be living in many other areas.
Aaron MacNeil of the Australian Institute of Marine Science, Townsville, Queensland, told the BBC in 2014: “They could be anywhere that is cold enough and deep enough.”

However, from the early 20th century through the 1960s, these sharks were commonly fished for their liver oil, which was used as lamp fuel and industrial lubricant. In a few years, over 30,000 were taken.
This led Aaron Fisk of the University of Windsor in Ontario to believe that “they are quite common”.
He added: “When we want to catch them we have no problems.”
