We know very little about the oceans, which cover 70% of our planet, and the total number of organisms living in them far exceeds the total number of organisms living on land. Rushing currents in all directions and the ever-changing rays of the sun hold the fate of marine life in their hands. This program introduces marine life: blue whales, tuna, hammerhead sharks, yellow and brown whale sharks, bonnetheads, black-browed albatrosses, leatherback turtles, and vultures.
