案例简介：照片由 @ acacia.johnson/我一直对海象着迷。几百万年来，还有什么其他物种进化成专门的蛤蜊食食者，长有三英尺 (1米) 长的象牙和变色皮肤，厚度可达4英寸 (10厘米) 厚？它们几乎太奇怪了，看起来不像是真的 -- 但是海象确实是真实的、美丽的、超凡脱俗的，随着北极气温的升高，它们越来越值得关注。今年夏天，我去了阿拉斯加的海象群岛国家野生动物保护区，每年夏天，雄性太平洋海象聚集在这里已有数千年的历史了-国营游客计划允许旅行者在这个古老栖息地的中心露营。请点击bio中的链接，以了解有关海象在海洋生态系统中的经验和重要作用的更多信息。# 海象群岛 # 阿拉斯加 # 朗迪斯兰

案例简介：Photo by @acacia.johnson / I've long been fascinated by walrus. What other species has evolved over millions of years into a specialized clam-eater, with three-foot (1m) tusks and color-changing skin that can be up to four inches (10cm) thick? They're almost too strange to seem real—but walrus are indeed real, beautiful, and otherworldly, and increasingly deserving of attention as temperatures rise across the Arctic.This summer, I traveled to Alaska's Walrus Islands State Game Sanctuary, where male Pacific walrus have gathered each summer for thousands of years—and where a state-run visitor program allows travelers to camp in the heart of this ancient habitat. Follow the link in bio to read more about the experience and the vital role that walrus play in the marine ecosystem. #walrus #walrusislands #alaska #roundisland
