案例简介：照片由 @ amivitale/一只网状长颈鹿在肯尼亚北部的 @ r.e.s.c.u.e吃草。由于它们的脖子很长，网状长颈鹿必须张开双腿才能到达地面上的叶子或水源。为什么长颈鹿的脖子这么长，存在各种各样的假设。有人说这是为了获得高食物来源; 另一些人说，长脖子是性选择的结果，还有一些人认为，这些长脖子可以让他们在炎热的非洲阳光下更好地冷却自己。三十年来，长颈鹿的数量下降了近40%，网状长颈鹿的数量少于16,000。这种下降被认为是由栖息地的丧失和破碎以及偷猎引起的，但是由于过去缺乏长期的保护工作，很难知道。通过阅读我的 @ natgeo故事 “如何拯救世界上最高的动物”，了解更多信息。@ 长颈鹿 _ 保护 @ sdzsafaripark @ thephotociety # 长颈鹿 # 阻止偷猎 # 肯尼亚 # 保护

案例简介：Photo by @amivitale / A reticulated giraffe grazes at @r.e.s.c.u.e in northern Kenya. Because their necks are so long, reticulated giraffes must splay their legs in order to reach leaves or water sources on the ground. A variety of hypotheses exist for why giraffe necks are so long. Some say it is to reach high food sources; others say the long neck is the result of sexual selection, and still others suggest these long necks allow them to better cool themselves under the hot African sun. Giraffe populations have dropped nearly 40 percent in three decades, and reticulated giraffe number fewer than 16,000. The decline is thought to be caused by habitat loss and fragmentation, and poaching, but with the lack of long-term conservation efforts in the past, it's hard to know.
