  • T. S. Kemp


Virtually all mammals can swim at least sufficiently well to cross bodies of water, but the extent of specific adaptation for aquatic life varies amongst different mammals from no more than modified behaviour like the Japanese macaque monkeys spending their days sitting in hot springs, through different degrees of amphibiousness to the permanently marine whales and dolphins, dugongs and manatees that cannot come out onto land at all. ‘Aquatic mammals’ first discusses the mammals living in freshwater that have evolved various degrees of aquatic adaptation before considering the marine mammals such as pinnipeds (sea lions, seals, and walruses), sirenians (dugongs and manatees), and cetaceans (whales, dolphins, and porpoises).
