EPISODE 8 — THE BLUE WHALE'S TAIL (GIANTS)

In this episode of Corwin's Quest, Jeff encounters some of the biggest animals on our planet. His main quest is to confront the most colossal creature that has ever lived, the mighty blue whale. Jeff teams up with a team of scientists to help track down this leviathan, but it's not as easy to find as you might think.

Along the way, Jeff spots soaring storm petrels, diving Dall's porpoises, a cruising humpback whale and a strange but beautiful ocean sunfish (Mola mola).

But that's not all. In a series of side quests, Jeff goes ape for mountain gorillas (the world's largest primates), wrestles a reticulated python (the world's longest snake) and feeds a friendly Goliath beetle (the world's biggest insect).

Corwin's Clip Jeff learns that even the biggest animals can vanish before one's very eyes in this clip from "The Blue Whale's Tail (Giants)."

Featured Creatures From pythons to Goliath beetles, meet the critters Jeff encounters in this episode of Corwin's Quest.
