The Blue Planet: Ocean World Class notes 21 Aug 08 The biggest animal ever to live on the planet: The blue whale, one of the fastest animals in the sea and feeds almost exclusively on krill (a small crustacean). A single blue what in one day can consume 40 million krill. Relatively little is understood of blue whales: Where do they breed? What else do we not know? The Pacific Ocean covers almost half of the globe. The ocean comprises 97% of the earth’s inhabitable space. Life in the ocean is not evenly spread. It is regulated by the occurrence of nutrients and the varying power of the sun. The shear physical power of the ocean dominates our planet. How? The ocean profoundly influences the weather of all the world. How? When a wave reaches shallow water it starts to break. How? Currents keep the waters of the ocean moving and they are responsible for transporting nutrients within the ocean. Isolated seamounts create oases where life can exists in high densities. The deep ocean currents combine with the isolated sea mounts and upwell bringing rich nutrients up from the deeper waters. Tuna often feed on plankton feeding fish.
