Bactrian camels live not in shifting Sahara sands but in Central and East Asia's rocky deserts.
Bactrian camels have developed special adaptations to allow them to survive in such a brutal environment. One is a thick, shaggy coat that protects them in winter and falls away as seasons change and temperatures rise. Like Arabian camels, Bactrians rarely sweat, helping them conserve fluids for long periods of time. In winter, plants may yield enough moisture to sustain a camel without water for several weeks.
When camels do refill, however, they soak up water like a sponge. A very thirsty animal can drink 30 gallons of water in only 13 minutes. Like Arabian camels, Bactrians' nostrils close to keep sand at bay, and their bushy eyebrows and two rows of long eyelashes protect their eyes. Big, flat footpads help them navigate the rough rocky terrain and shifting desert sands without sinking under their own massive bulk or the weight of heavy packs. The only truly wild camels that still exist are Bactrian camels.
These herds survive in the Gobi Desert of Mongolia and China. All rights reserved. Common Name: Bactrian Camel. Scientific Name: Camelus bactrianus. Type: Mammals. Diet: Herbivore.
Group Name: Flock, caravan. Size: Over 7 feet tall at the hump. Yes, camels! Walking around on ice and snow. It's true. In , scientists announced they'd discovered mummified leg bones on Ellesmere Island, which belonged to the ancestors of modern-day one- and two-humped camels. In fact, enduring the frigid tundra is how scientists think camels got their iconic hump in the first place, because what's inside helped them survive in an age when many other animals were wiped out.
John Hare: What's inside a camel's hump is fat, and a lot of people think it's water. But it's certainly not; it's fat, and it nourishes them when they're on long journeys. Narrator: That's right, fat.
Each hump can store up to 36 kilograms of it, which can sustain the camel for weeks or even months without food. And that sort of adaptation was especially important 3. Hare: Talking about the Ice Age, when a lot of mammals were killed during that time, and yet the camel managed to survive by developing this emergency food system, if you like: the hump. Narrator: Eventually, camels migrated across the Bering Strait into regions of Asia and Africa, where the fat inside their humps helped them adapt yet again.
This time, to the blistering-hot temperatures of deserts like the Gobi and Sahara. You see, camels are one of the only animals in the world that store all their fat in one spot. And that's useful for keeping cool in a hot climate because heat can escape faster from the rest of their body, which helps them maintain a lower body temperature.
