Join shark expert Greg Skomal as he ventures under the Arctic ice in search of the Greenland shark. Sharing this icy, blue twilight with an apex predator is a thrill--so long as you don’t end up being mistaken for a ringed seal, the shark’s favorite meal. In this episode, we’ll learn how Skomal’s research is revealing how these evolutionary survivors endure despite astonishing obstacles.

Summary[edit] Description: Sand tiger sharks can't help but drop their jaws at the incredible history in and around Monitor National Marine Sanctuary! Though the sanctuary was established to protect the wreck of the USS Monitor, the sanctuary is considering an expansion that could protect many other ships within the Graveyard of the Atlantic. Here, a sand tiger shark swims around the wreck of Caribsea, a 1919 freighter sunk by a German U-boat during World War II. Laden with heavy cargo, Caribsea sank in less than two minutes after being struck by a torpedo in the middle of the night. The abrupt strike left no time for lifeboats to be launched. Survivors of the attack were forced to flee their bunks and jump into the sea, where they would drift, clinging to the wreckage, for some 10 hours before rescue. A few days after Caribsea sank, a man living in North Carolina's Outer Banks discovered a framed certificate drifting up on the surf during a walk on the beach. The certificate, he would find, belonged to his cousin, a Caribsea crewmember, and would confirm the tragic wreck of the Caribsea for the community. Photo Credit: NOAA. Date: 31 October 2016, 14:28.
