This instalment is the first of several to concentrate on mammals. The platypus and the echidna are the only mammals that lay eggs (in much the same manner of reptiles), and it is from such animals that others in the group evolved. Since mammals have warm blood and most have dense fur, they can hunt at night when temperatures drop. It is for this reason that they became more successful than their reptile ancestors, who needed to heat themselves externally. Much of the programme is devoted to marsupials (whose young are partially formed at birth) of which fossils have been found in the Americas dating back 60 million years.

With 40 species of shark calling these warm waters home, scientists are seeing new animal behavior around every corner. Whitetip reef sharks “sleep” in tight volcanic tunnels. In the deep water, everything is on the menu for the hunting Tiger shark, from birds to Humpback whales. Hopping from island to island, uncover surprising moments of cooperation, rarely seen hunting tactics and striking insights into these predators of the world’s paradise.

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.
