Jenner’s zeal for her work is palpable as she narrates her team’s findings, and is understandable given the extraordinary nature of her encounters with humpback, pygmy blue, and minke whales. The conversational tone with which she relates these experiences, while clearly conveying her passion for her subjects, does not always allow for seamless interweaving of personal narrative and marine biology. While much of the book focuses on these personal encounters, it is when Jenner moves into the more familiar territory of scientific reportage that her writing becomes more confident and engaging.

Jenner’s dedication to long-term data collection on all aspects of whale and dolphin ecology has done significantly more than enhance scientific knowledge. It has been a powerful form of environmental advocacy. Through enhancing knowledge of whales’ critical habitats, the Jenner family’s work has led to the protection of these vital regions in Australian waters. The Jenners, as both scientists and co-founders of the Centre for Whale Research (WA), have made unparalleled contributions to marine biology in Australia. If this account of their work stimulates renewed public support for cetacean conservation and marine protection, it will prove a valuable addition to the genre of popular science.
