If this Maasai giraffe wasn't silhouetted by the sunset, we'd be seeing its telltale spots—a jagged, leaflike pattern unlike the smooth-edged tessellations pasted upon most giraffes. While all giraffes are technically classed as subspecies of Giraffa camelopardalis, the Maasai giraffe's genetics are distinct enough that some scientists say it should be its own species. Recent research shows more DNA diversity among giraffes than once thought, suggesting the Giraffa genus should include up to eight full-fledged species, not just one.
水上漂?
踩着高跷的影子
眺望平静的海面
重生的桥梁
一片广阔的北极地区
大海、沙滩和日落
一个湖泊,三个国家
照亮迷雾
