Synopsis

Bathed in bright sunlight and warm clear water, the coral reef is a rich oasis of life - the rainforest of the sea. Bizarrely adorned harlequin shrimp carry off a starfish several times their size, while haunting songs reverberate around the reef, heralding the arrival of humpback whales. Shimmering schools of brightly colored fish battle for territory in this competitive world where you have to stand out to survive.
