Ebook: Listening to whales: what the orcas have taught us

In Listening to Whales, Alexandra Morton shares spellbinding stories about her career in whale and dolphin research and what she has learned from and about these magnificent mammals. In the late 1970s, while working at Marineland in California, Alexandra pioneered the recording of orca sounds by dropping a hydrophone into the tank of two killer whales. She recorded the varied language of mating, childbirth, and even grief after the birth of a stillborn calf. At the same time she made the startling observation that the whales were inventing wonderful synchronized movements, a behavior that was soon recognized as a defining characteristic of orca society.
