A Southern Right Whale "sailing" in Wittsan Bay. A "sailing" whale will stand on its head and hold its tail upright out of the water for 30-60 seconds. It is speculated that they are doing this to cool their bodies. They have just spent the prior months in cold Antarctic waters feeding to build up a layer of blubber. They come to these warm water bays to give birth to their young, who cannot survive in cold waters at an early age. The tail (flukes) of the whale is filled with many blood vessels, and it is thought that the evaporation of the water from the tail while it is exposed to air may provide some cooling effects. Shots from the Cape Town area and our journey. See the "e-postcard from KwaZulu-Natal" for descriptions and information.
