What a bunch of adorable, loving creatures! I simply burst out laughing while watching this video. Did you know that there are around 35 species of seals, and only six types live in Antarctica? These six species make up the majority of the world’s seal population. They have no natural land predators anywhere around, such as polar bears or man. That’s why the seals from the video didn’t hesitate to approach Charlie. Even though, most of seals don’t have ears, they hear perfectly even under the water. Seals use a type of sonar to locate food, kind of what dolphins and whales use. In addition it is believed that seals use their whiskers as a form of radar. Their whiskers detect movement in the water. Thanks to that, seals can find food in complete darkness better than in the light. In the water, a seal’s nose closes automatically and stays this way until the animal comes to surface. A seal can remain underwater for 15 minutes to 30 minutes, they sleep just under the surface of the ocean and can resurface for air even without waking up.
