骆驼属

• Viable first-generation hybrids of one-humped and two-humped camels, called "nar", are possible. These hybrids result from crossing these two species.
• Camels can survive without water for up to two weeks, and without food for a month. Their blood does not thicken even after prolonged absence of drinking.
• Camels can pull a load weighing up to 50% of their own body weight. They are used as draft animals from 4 to 25 years old.
• Camels can go a long time without water, losing up to 40% of their body weight. In one experiment, a camel lost 100 kg in 8 days without water, then drank 103 liters in 10 minutes.
• Camels have excellent vision: they can see a walking person from a kilometer away, and a moving car from 3–5 kilometers. They can also smell fresh pasture or fresh water from 40–60 kilometers away.
• Camels can sense the smell of water and storm clouds from 40–60 km away. They head toward storm clouds to reach places where rain will fall.
• Camels have humps on their back where they store fat. Water is not stored in the humps, but fat accumulates there, which is converted into water during severe thirst.
• Camels closely related to modern ones diverged in North America with the emergence of a savanna-like landscape. This happened due to large spaces where anatomical features adapted to dry and harsh climate arose.
• Camels have calluses on their chest, wrists, elbows, and knees. These calluses allow them to lie on hot ground, the temperature of which can reach 70 °C.
• A camel with a rider can travel up to 100 km per day, moving at a speed of 10–12 km/h. It is capable of covering such distances even during long journeys.
• Dromedaries produce an average of 2000 kg of milk per year, while the bactrian camel's yield may exceed 4000 kg. For Bactrians, the yield is 750 kg, according to other data—600–800 kg.
