With forelegs braced, bulls swing their necks and club each other with their skulls, aiming for the underbelly. A study in 2016, however, determined that habitat loss resulting from expanding agricultural activities, increased mortality brought on by illegal hunting, and the effects of ongoing civil unrest in a handful of African countries had caused giraffe populations to plummet by 3640 percent between 1985 and 2015, and, as of 2016, the IUCN has reclassified the conservation status of the species as vulnerable.

The second least-populous species is the reticulated giraffe, whose stronghold is in northern Kenya. That means giraffes can afford to be pickier than most big animals, and they're also better able to cope with droughts than smaller animals, as the tallest trees tend to have the deepest roots that reach down to water that other trees can't access. Explanation: Clumped distribution is always due to the inequality distribution of nutrients in the environment. This photo was submitted to Your Shot, our photo community on Instagram.
