An international team of researchers has found that one of the aquatic predator moves at a speed of up to 8 times smaller than the speed of movement on land leatherback turtles.
It is the most representative of the slow sharks - Greenland. Using special tags, sensors, scientists measured the speed with which the average move Greenland shark. It is an average of only 1.2 km / h
Yuki Watanabe of the Japanese Institute of Polar Research notes that, given the ratio of the size of Greenland sharks and the speed of their movement, these predators can be recognized by the slow fish in the ocean. Researchers believe that such a low speed that allows sharks save energy as they live in cold arctic waters, in which the water temperature is in the range of 2
