This episode explores predation, symbiotic relationships, and dangerous lifestyle of various animals around the world. The predation stories include: a relatively small spider snags a bat and makes a meal out of it; a polar bear pounces on a ring seal, making the bear’s white fur red; a fox pounces gracefully again and again, nose first into the snow, until it catches a vole; chimps hunt for other primates, flinging themselves through trees in pursuit. The symbiotic relationships are: the friendship between hippos and crocs; gobies clean tiger groupers; petizan shrimp clean Nassau groupers; hogfish pluck parasites off Creole wrasses; badgers and coyotes are hunting partners; and the one-sided friendship of a sargassum fish that has camouflaged itself as a sargassum plant, and hides out in the plant waiting for prey. The life of danger stories are: a young gazelle becomes hunting practice for a cheetah cub; four species of birds try to live on the edge of a dwindling water source amid chomping crocodiles; marine iguanas encounter danger after danger from the moment they are born, including incidents involving a hawk, a snake, a heron and some sea lions.
