New Zealand Sea Lion Fact File
Size: Females grow up to 2m long and can weigh up to 160kg whilst males can reach 3.5m in length and weigh up to 450kg!
Distribution: The main breeding populations are at the Auckland and Campbell Islands in the New Zealand sub Antarctic, where approximately 99% of the species’ annual pup production occurs
Diet: This species has a wide diet, consisting of fish e.g. Patagonian toothfish, cephalopods, crustaceans, seabirds and other marine mammals
Behaviour: Unlike other species, in the breeding season, female sea lions move inland with their pups to protect them from harassment by males, wind, storms, and potential parasitic infections. They can move up to 2km inland – they are only pinniped species to disperse this far inland, and have a preference for forests
IUCN Status: Endangered. Threats include harvesting, fishery bycatch, food scarcity and mainland threats that result in a loss of pups e.g. by human disturbance
