Unlike the hippos, camels and lamas inhabit the dryland space. These are quite big animals (llamas weigh around 100kg, while camels reach half a ton) also belong to the cloven-footed; however, sometime people allocate them into a separate type, the so-called tylopoda.
They were called so, because of their flexible “cushions” on the toe ends covered with a thick rough fur that resemble the corns. Thanks to them, these animals cannot feel the red-hot sand underneath; so, this means that camel actually has no hooves; we should better call them the “nails”.
The tylopoda type has got long legs; the long and thin neck holds comparatively small head with soft lips that can easily grasp the dry prickly vegetation that serves them as a food. The whole body is covered with long thick fur, especially if we take lamas. And this is no surprise as they live far high in the heavy-frosted and windy Andes in wintertime.
The ships of the forest (i.e. the camels) of Asia you can see humps, by the number of which we distinguish them between single-humped or double-humped. The humps serve them as the fatty deposits due to which these animals can easily stand the drought.
The water enters the organism when the fat gets melted, which explains the point, why animals can dispense with water for several weeks, especially when there is a possibility to refect by eating the grass. Nevertheless, as soon as they reach the water-hole they can drink up to 50 liters of water at a blow; although not exclusively the soft water, but also the salt water. By this only feature the single-humped camels are kept as domesticated animals of Arab-Bedouin passing over the North African and Arabian deserts. The camels also serve as a baggage and mounting animals, as well as the source of fur and meat. The double-humped camels perform the same role in the Central Asian deserts.
