Elephant Seal Keeper’s Bible is a serious, welfare-first handbook for the small community of professionals who work with elephant seals in rehabilitation centres, aquariums, research stations and other licensed institutions. It is not a guide to private ownership: throughout the book, elephant seals are treated as what they are – huge, powerful, deep-diving marine mammals whose needs can only be met in carefully designed, heavily regulated facilities. Elephant seals are built for life in cold oceans and at great depths, not for small pools or improvised pens. Their size, diving physiology, social dynamics and intense haul-out behaviour place unique demands on space, life-support systems, handling protocols and veterinary care. This book translates wild elephant seal biology into concrete decisions about design, husbandry, safety and ethics, from the first intake exam to the last day of care. Inside Elephant Seal Keeper’s Bible , you will discover: - Wild ecology, practical lessons – how migration, fasting cycles, breeding beaches and deep-diving behaviour shape requirements for pool volume, haul-out space and daily routines. - Facility and life-support design – cold-water systems, depth, circulation, filtration, shade, acoustics and safe keeper access in environments built for animals that can exceed a tonne in weight. - Rescue, stabilisation and rehab – triage, transport, fluid and nutritional support, minimising stress and planning from day one for either release or long-term placement. - Feeding and body condition – high-energy diets, weight tracking, fasting periods, safe feeding strategies and preventing both under- and over-conditioning. - Handling, training and safety – protected-contact principles, shifting and transport, medical behaviours, emergency drills and realistic boundaries around human–animal interaction. - Health and veterinary care – common medical issues in elephant seals, early warning signs, diagnostics at scale, anaesthesia risks and post-procedure management. - Welfare, ethics and mission – structured welfare assessments, end-of-care decisions, regulatory frameworks and linking each individual’s story to honest education and conservation work. Written in clear, professional language, Elephant Seal Keeper’s Bible gives keepers, veterinarians, life-support technicians, managers and students a shared framework for modern elephant seal care. Whether you are planning rare intakes, refining an existing programme or training new staff, this handbook keeps one priority at the centre of every chapter: doing right by a demanding ocean mammal whose size and biology leave no room for casual, improvised care.
