OREANDA-NEWS Scientists from the University of Florida were able to photograph an extremely rare six-gill shark Hexanchus griseus. This was done during an expedition to study and chip these grandiose sea creatures. 

This species of sharks usually live at a depth of about 2500 meters, rising to the surface in very rare cases and only in the dark. Therefore, their study is a rather complicated process. Meanwhile, these sharks are of particular interest to scientists, caused among other things by the fact that they practically did not evolve and actually remained the same as they were during the Jurassic period. 

In the course of a new study, biologists were able not only to install sensors on a large male, but also to photograph another shark in natural conditions. An adult reaches a length of 8 meters and in some cases lives up to 80 years. According to experts, such a meeting with a shark in its midst is a tremendous success and this can be compared with a meeting with a dinosaur. 

Now, scientists hope that the installed sensors will allow a more complete study of the lifestyle of these prehistoric, but modern animals, which will give an idea of the life of their distant ancestors.
