Shark Discovery: Greater number of mysterious predators than great predators lurking in the depths of the sea. Science | news


The great white is a species of giant mackerel shark famous for its challenging size, with a length of up to 20 feet – but most are very small, with an average of about 15 to 16 feet of females and males between 11 and 13 feet Has an inclination. . Able to survive for 70 years or more, these top predators can swim at speeds up to 16mph for short bursts and are one of the deadliest predators of the ocean. But, the colossal is another species of monsters that inhabit the depths of the ocean and deter scientists for years.

Resembling a vast section of weather-reefed rock, Greenland sharks can grow up to 24 feet long – making them the largest and largest of all fish in the Arctic.

But this is about his comparison with those great white goes.

Their maximum speed is a sluggish 1.7mph, many are almost blind, and most are just happy with the rotting carpet.

Studies in the Arctic have revealed some snippets of information about Greenland sharks, but as they live in deep, cold water, humans rarely catch a glimpse.

They only come close to the surface in places where shallow waters are sufficiently rigid for them – mainly around Greenland and Iceland.

As a result, they were long thought of as purely polar animals, such as closely related Pacific sleeper sharks and southern sleeper sharks.

But they have been reported on the coasts of Canada, Portugal, France, Scotland and Scandinavia, so scientists believe they may live in many other areas.

“They can be everywhere that’s cool and deep enough,” Aaron McNeill of the Australian Institute of Marine Science told the BBC in Townsville, Queensland in 2014.

However, from the early 20th century through the sixties, these sharks were commonly used for their liver oil, which was used as lamp fuel and industrial lubricants. In a few years, more than 30,000 were taken.

Aaron Fisk from the University of Windsor, Ontario, believes that “they are quite normal.”

He said: “We have no problem when we want to capture them.”
