     Camels are large animals living in dry areas. There are two species of camels: the Arabian camel

with a single hump from the dry desert, and the Bactrian camel with two humps from Centraland East

Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years .

Most camels are domesticated(驯化)and fed by people. Camels are plant-eaters.

     Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees

and chest. Camels have nostrils(鼻孔)that can open and close, protecting them from the desert

environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth

is extremely tough, allowing camels to eat thorny(带刺的)desert plants. Their widened feet help them

move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the

intense heat from desert sand. Their long legs help by keeping them further from the hot ground.

     Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is

commonly believed. The humps are actually a container of fat. Camels are incredibly(难以置信)

well-adapted to their environment. When conditions heat up, camels can increase their own body

temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day.

     Camels are sometimes called "ships of the desert" because people ride them around the hot, dry

deserts of the world. However, the number of camels is becoming smaller for various reasons.
