案例简介：@ bertiegregory的视频 | 旋转海豚在红海的埃及南部海岸旋转。当它在我周围游动时，它会以圆形模式移动头部和下巴-海豚使用回声定位来分析它们的环境。通过发射一系列高频声音，然后监听这些声音的反射，他们可以确定物体的距离及其构成。科学家发现，海豚的讲台 (长鼻子) 的不同部分具有不同的导电特性，通过旋转其头部和下巴，它能够更好地解释回声定位反射-类似于蝙蝠如何旋转耳朵以聚焦声音。关注 @ bertiegregory，了解更多野生动物冒险!# 红海 # 海豚 # 水下 # 海洋

案例简介：Video by @bertiegregory | A spinner dolphin whirls off the coast of southern Egypt in the Red Sea. As it swam around me, it would move its head and jaw in a circular pattern—dolphins analyze their environment using echolocation. By firing out a series of high- frequency sounds and then listening for the reflection of those sounds, they can determine the distance of an object and what it’s made of. Scientists have found that different parts of the dolphin’s rostrum (the long snout) have different conductive properties, and by rotating its head and jaw, it's able to better interpret the echolocation reflections–similar to how bats rotate their ears to focus sounds.
