Leopard seal
They can hold their breath for 15 minutes and are the second-largest type of seal in Antarctica and the third-largest worldwide. Leopard seals can even sing and smile underwater! They communicate by using clicking or trilling noises. When interacting with humans in the water, they are more curious than aggressive. They have a thick layer of fat called blubber under their skin to keep them warm under the icy freezing water. They weigh between 800 and 1,300 pounds which are heavier than a horse. They stay in Antarctica and sometimes come to New Zealand during the hot summer. Male seals are called bulls, females are called cows, and babies are called pups.
