Camel
Summary
A camel (from camelus and κάμηλος (kamēlos) from Ancient Semitic: gāmāl) is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The wild Bactrian camel is a separate species and is now critically endangered.
The word camel is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the llama, the alpaca, the guanaco, and the vicuña, which belong to the separate tribe Lamini. Camelids originated in North America during the Eocene, with the ancestor of modern camels, Paracamelus, migrating across the Bering land bridge into Asia during the late Miocene, around 6 million years ago.
Three species are extant:
The average life expectancy of a camel is 40 to 50 years. A full-grown adult dromedary camel stands at the shoulder and at the hump. Bactrian camels can be a foot taller. Camels can run at up to in short bursts and sustain speeds of up to . Bactrian camels weigh and dromedaries . The widening toes on a camel's hoof provide supplemental grip for varying soil sediments.
The male dromedary camel has an organ called a dulla in its throat, a large, inflatable sac that it extrudes from its mouth when in rut to assert dominance and attract females. It resembles a long, swollen, pink tongue hanging out of the side of the camel's mouth. Camels mate by having both male and female sitting on the ground, with the male mounting from behind. The male usually ejaculates three or four times within a single mating session.
