Hooker's sea lion, also known as the New Zealand sea lion, is a marine mammal native to the coasts of New Zealand. It is characterized by its robust body, short limbs, and a thick layer of blubber, which helps it stay warm in cold waters. Adult males can weigh up to 400 pounds, while females are smaller, typically weighing around 150 pounds. These sea lions primarily inhabit subantarctic islands and the southern coast of the South Island. They are known for their social behavior, often seen lounging on beaches or rocky shores. Hooker's sea lions are classified as endangered due to habitat loss and human activities, making conservation efforts essential for their survival.
