Mammals such as deer, adapt themselves in grasslands, with their skinny legs it could run faster and tail serves as warning purposes. In case of danger deer will tail up to show signals to its peers. Fur presented on the skin make them safer during winter. Whereas animals living in deserted areas such as camels use its long eye lashes and nostrils to protect themselves from hot weather and air. At a single session, camel can drink up to 46 litres of water and can store for future purposes.
