The Blue Planet (2001)

Episode Overview

With the lengthening days, countless tiny plankton flourish in the warm sunlight. In these temperate waters, massive basking sharks, weighing three tons, feed among towering giant kelp—the fastest-growing plant on Earth. These underwater forests are home to a diverse array of creatures, such as playful sea otters, vibrant anemones, agile squid, and stunning leafy sea dragons. However, as the year progresses, fierce storms sweep through the frigid seas, posing a significant challenge for the creatures that endure.
