海豚··翻译!海豚的大脑由完全隔开的两部分组成,当其中一部分工作时,另一部分充分休息,因此,海豚可终生不眠. 海豚是靠回

The brain of a dolphin is composed by two completely separated parts。One part is resting adequately when the other part is working。Therefore,a dolphin can keep awake for the whole life。A dolphin judge the distance,direction,position,shape and even the nature of the objective by the echolocation。Even if the water is mudded,it can still chase its food rapidly and accurately。In the process of collective prey,there is always a fixed one playing the role of "driver" and other dolphins play the role of "barriers"。The "driver" will be responsible for driving ambient fish into the encirclement composed by "barriers"。
