Sea lions are known as the largest mammals found in New Zealand. Males are considerably bigger and heavier than females, an average sea lion grows up to 3 meters long and weighs nearly 450 kilograms. Sea lions densely populate sandy beaches of the South Island and the Auckland Islands. The best time to observe huge mammals is during their breeding season that stretches from November to January. The animals are polygamous, and perhaps owing to this fact they are also called Hooker's Sea Lions. Like fur seals, sea lions appear to be quite aggressive, yet this time not because of the fear of a threat, but through their fights for breeding locations which occur between the bulls usually in November: all the territories must be divided before the females' arrival.

How do sea lions reproduce and why are they called Hooker's Sea Lions?
Sea lions engage in polygamous mating with males mating with multiple females. They create harems of females, defending them from rival males. Hooker's Sea Lions are named after Sir Joseph Hooker, a botanist and companion of James Clark Ross, and were first described by German biologist Georg Heinrich von Langsdorff during the early 19th century. The name 'sea lion' refers to the barking sounds they make and the curiously maned fur around the necks of adult males. Show more
What is territorial conflict among sea lions, and when does it occur?
During breeding season, males of sea lion species fight against each other with vocalizations and posturing to establish dominance for the best breeding locations. These fights occur in November before female arrival and can be vicious, resulting in serious injury or death. Visitors should maintain a safe distance and observe them without interfering.
