RSPB Spotlight Seals is packed with eye-catching, informative color photos and features succinct, detailed text written by a knowledgeable naturalist.
Spotlight Seals explores the intricate lives of the UK's native Grey and Common Seals and their amazing physical and behavioral adaptations to a life split between land and sea. Seals are the sleekest and most agile of all marine mammals, and they are superbly adapted to the watery world in which they spend most of their time. With their whiskery dog-like faces, curious nature and vulnerable pups, they are enduringly appealing animals. Although air-breathing, these marine mammals are superbly tuned to hunt, sleep, mate and keep warm while out at sea, but they remain inextricably linked to land where they moult and have their pups.
Frances Dipper also delves into the complex physiology that allows seals to dive deep and for long periods without coming to any harm. Once ruthlessly exploited for their meat and skins, seals now have protection around the British Isles. Their numbers are increasing, but they now face the new danger of plastic litter in their environment. Frances Dipper also explores age-old legends, interactions between humans and seals, and the best places to watch them in the UK. **
