This specific type of seals – the elephant seals, named like that because of their trunk, have weird feats that no animal on this world have. It is scientifically proven that the elephant seal can go underwater deeper than any other animal and stay there longer than anyone, even human divers. The scientists were troubled with the question how it manages to breathe or to conserve oxygen from the surface for so long. Finally the put the camera and various metabolism measuring tools, and they found out that what this animal does is really amazing. First thing, it doesn’t carrymuch oxygen in the lungs at all. It conserves it in the blood and muscles, and the spleen also serves as a reservoir. Thats the secret of its ability to spend so much time so deep underwater, up to 50 000ft! Another amazing feat of this weird animal is that, in order to spend oxygen slower and economically, it slows down its heart beat rate from 120 to just 6 beats per minute, sometimes even to just 2 beats! I mean, how amazing this really is!
