Seals are the acrobats of the sea, but they are very clumsy on land. A seal easily races through the water at 35 kilometers per hour, while it is lucky to cover 2 kilometers per hour on land. With its cute, round eyes, seals see very well under water. However, they would need eyeglasses to see sharply above water. Seals are completely adapted to life under water. Nevertheless, you can spot them regularly on the surface. They like to lie in the sun while resting on a sandbar or beach.
