The New Zealand Sea Lion, also known as the Hooker's sea lion, is a large marine mammal native to New Zealand. They are one of the rarest sea lion species in the world, with a population primarily found on the sub-Antarctic islands and the southern coast of New Zealand. Adult males can weigh up to 400 pounds, while females are smaller, averaging around 150 pounds. These sea lions are known for their distinctive features, including a thick neck and a mane in males. They primarily feed on fish, squid, and crustaceans, and are often seen resting on beaches or rocky shores. Conservation efforts are in place to protect their dwindling numbers due to threats like habitat loss and human activities.
