骆驼是昼夜生物,这意味着它们在白天活跃。它们依赖于植被,如低洼草和其他棘手和咸的植物。为了达到这种低洼的植物和草,骆驼已经形成了一个分裂的上唇结构,使得它们的上唇的每一半可以独立移动,这有助于它们吃低洼的植物和草。与奶牛类似,骆驼将食物从胃里回流到嘴里,这样他们就可以再次咀嚼食物。骆驼可以比其他哺乳动物更快地补充水分。他们据称在10分钟内喝了大约30加仑的水。骆驼在由一个显性雄性和一些雌性组成的畜群中旅行。根据物种,雄性公牛的高峰生育力(称为车辙)发生在一年中的不同时间。 Bactrian的生育高峰出现在11月至5月,而单峰骆驼可以全年达到高峰。雄性通常会与六个左右的雌性交配,尽管一些雄性可以在一个季节与50多个雌性交配。雌性骆驼的妊娠期为12至14个月。在分娩的时候,准妈妈通常会与主要的牛群分开。新生小牛可以在出生后不久走路,仅仅几周后,母亲和小牛就会重新加入更大的牛群。单胎是最常见的,但据报道有双胞胎出生。

Camels are day and night creatures, which means they are active during the day. They depend on vegetation such as low valerian and other thorny and salty plants. In order to achieve such low-lying plants and grasses, the camels have formed a split upper lip structure, allowing each half of their upper lip to move independently, which helps them eat low-lying plants and grasses. Like cows, camels return food from their stomachs to their mouths so they can chew food again. Camels can replenish water faster than other mammals. They allegedly drank about 30 gallons of water in 10 minutes. Camels travel in a herd of dominant males and some females. Depending on the species, the peak fertility of male bulls (called ruts) occurs at different times of the year. Bactrian’s birth peak appears between November and May, while the dromedary camel can reach its peak throughout the year. Males usually mate with six or so females, although some males can mate with more than 50 females in a season. The female camel has a gestation period of 12 to 14 months. At the time of childbirth, expectant mothers are usually separated from the main herd. Newborn calves can walk shortly after birth, and in just a few weeks, the mother and calf will rejoin the larger herd. Singletons are the most common, but twins are reported to have been born.
