How Camels and Polar Bears Adapt
How Camels and Polar Bears Adapt
Camels
First, camels can store up to 50 gallons of water in one of their stomachs, which allows them to last up to five days in the desert without drinking any water. Their two-toed feet are designed to spread their weight, so that they do not sink into the sand. Their nostrils are narrow slits, and they have long eyelashes, which keep the wind from blowing sand into their nose or eyes. They can also store fat in their hump, which gives them energy when food is scarce, but unlike storing fat throughout the body, the fat in the hump will not insulate them in hot conditions. Camels, because of the shape of their blood cells, can lose up to 25% of their bodily fluids without dying, unlike the 15% limit for most mammals.
Polar Bears
A polar bear lives in the cold, snowy Arctic lands and it is adapted to its environment in that it has a white fur which helps it blend in with the snow and ice. It also has a layer of fat under its skin, which helps it stay warm. A bear also has a thick layer of fur for warmth purpose. It has wide, large paws that help it to walk in the snow. Its nostrils have the ability to close, a feature which helps the polar bear swims under water without water getting into its system. They also have sharp claws making catching their prey an easier task. They have small ears to reduce the amount of heat lost. They have strong legs for catching prey and running.
