We Were Wrong About the Mariana Trench Abyss

Описание: Descend into the freezing abyss where time stands still and the laws of biology are broken. In this episode on Deep Sea Gigantism, we encounter the chilling Greenland Shark—a 400-year-old blind titan that has roamed the Arctic since the 17th century. From the crushing pressure of the Mariana Trench to the oxygen-rich polar seas, discover why creatures like the Bigfin Squid and Giant Isopods evolve into monstrous sizes to survive the eternal darkness.
