How long can a penguin go without food?

How long have sharks been in the ocean?

Sharks have swum in the oceans for almost 450 million years. But longevity is only part of the story. That extra few million years of evolution have enabled many shark species to develop some extraordinary abilities as perfect predators.

Do turtles have feet?

While most turtles have webbed feet, some, such as the pig-nosed turtle, have true flippers, with the digits being fused into paddles and the claws being relatively small. These species swim in the same way as sea turtles do (see below). Sea turtles are almost entirely aquatic and have flippers instead of feet.
