Researchers used cell-phone-like tracking devices, for example, to record the Arctic migration of narwhals, a whale with a long twisted tooth, and remotely operated submersible s to reach several kilometers down into the oceans to study delicate marine animals that are impossible to collect.

例如，考察者们使用电话式的跟踪器记录北极角鲸的迁徙，角鲸是带有一个很长的牙齿，从很远的地方就能探测到海洋里几千公里去研究那些不可能收集到的海底动物。
