As almost all animal inhabitants of Antarctica are forced to migrate north, the sea underneath the frozen ice still provides a home to many specially adapted fish whose cells are protected from freezing through an "antifreeze" liquid. Many of them feed on the faeces of other animals. The most notable larger animal that does not migrate north is perhaps the Weddell Seal, which can be found as close as 1300 kilometres to the pole. Groups of seals tear holes into the ice to dive for food and come up to breathe. The females come back to the ice to give birth.

The team set off beneath the waves to explore this spectacular archipelago. It is an exciting opportunity for the team to delve into a world that still largely remains a mystery to science. Venturing down in the Nadir, a specially equipped deep sea submersible, Liz goes in search of an elusive ocean giant, the mola, or sunfish, to understand more about its little-known behaviour in the deep. On the way back to the Alucia, Liz checks in on a playful sea lion population to see how they have been affected by a recent extreme weather event, El Nino. Back on board the Alucia, the team sets sail north for the most remote and inhospitable islands in the Galapagos - Wolf and Darwin. Here, Liz joins the team tagging and tracking hammerhead sharks that school at this location in huge numbers as they try to unlock the secrets of this stunning behaviour. But nothing can prepare the Alucia crew for the power of the ocean in this isolated marine wonderland.

In the thick of the jungle of Rwanda's Volcanoes National Park, an infant mountain gorilla has been caught in a snare. If the rope is not removed quickly enough, the young gorilla could lose its hand. In order to remove the snare, a team of veterinarians will first need to sedate the infant's mother. But if the infant screams too much, the three 400-pound adult males that form part of this gorilla group will all attack. Everything must go perfectly, or there's no telling what could happen. And being jungle medicine, things rarely go perfectly. The pioneering group of vets performing this medical intervention is known as Gorilla Doctors. Led by Canadian Mike Cranfield, they work in Rwanda, the Democratic Republic of Congo and Uganda, where the world's last Mountain Gorillas can be found.
