Penguin - the only bird that can swim but can not fly. In addition, it is the only bird walking standing. In this topic, I will tell you about these amazing creatures. Penguins - flightless waterfowl that live in the wild only in the lands of the southern hemisphere. Most penguins spends half his life in the ocean, and the other half on land. In general, most species of penguins live on Antarctica and in some other areas of the coldest hemisphere. Some few species can survive in temperate or even tropical latitudes. Generally penguins made for life in the sea. Some species spend as much as 75% of its life in the water, on land, they are chosen only to lay their eggs and wait for posterity. Heavy, hard bones are in the water as heavy belt diver, allowing penguins stay underwater. Their wings are shaped like fins, and help them to "manage" the movement of the water at speeds up to 15 miles per hour. Streamlined body like legs oar, an insulating layer of fat and waterproof feathers - all serve their efficient and comfortable stay under water. They also have a remarkable ability to dive deep (this will be discussed below). In addition, in order not to lose heat, penguins are tough, very compactly located feathers (up to 70 sq. Cm) to ensure waterproofing.
