The animal on the cover of Programming Perl is a dromedary camel.
The dromedary camel (Camelus dromedarius), also known as the “Arabian camel,” is a one-humped, even-toed ungulate, or hooved animal. Dromedaries are the largest members of the camel family. They have been domesticated for 3,500 years, and thanks to the many adaptations that allow them to thrive in the desert, they’re valued as beasts of burden.
The world’s dromedary camel population is mostly domesticated, with just one known wild population, located in Australia. Domesticated dromedaries inhabit the Middle East and North Africa, where they live in herds consisting of many females among a dominant male. The dromedary’s hump can store up to 80 pounds of fat, which can be broken down into water and energy, allowing it to travel in desert conditions for 100 miles without water. In addition to their ability to travel long distances in arid conditions without sustenance, dromedaries have double rows of eyelashes that keep sand out of their eyes, the ability to close their nostrils during a sandstorm, and unlike horses, they kneel for the loading of cargo and passengers. Their typical lifespan is 40 to 50 years.
