The establishment of the Indian Ocean Whale Sanctuary in 1979 gave whale science an opportunity and a challenge: the opportunity to study protected whale; and the challenge to show that whale populations can be monitored purely through studies of living animals. The sperm whale (Physeter catodon), is commercially the most important, and the most numerous, large whale. It may be a significant link in the food web on account of returning nutrients from the deep ocean to the surface through its faeces. Analysis of the composition of sperm whale catches suggests that the sperm whale possesses a unique and interesting social system (Best 1979), a thorough knowledge of which is essential if these exceptional animals are to be properly protected.It was thus appropriate to carry out a study of the behaviour of the sperm whales in the Indian Ocean, principally using the methods developed on living right, grey and humpback whales, and the money raised by WWF-Netherlands.
