When you think of dolphins, what comes to mind first?
Smiling Angel? Smart and cute? A good friend of human beings?
They are one of the most intelligent animal families, gentle and friendly, lively and active, and have always been loved by people.
In fact, dolphins are not "small animals" without stories!
Do you really know them?
<h1 class="pgc-h-arrow-right" Data-track="6" Why do > dolphins save people? </h1>
Dolphins, also known as "lifeguards at sea".
I believe that everyone has heard a lot of stories about dolphins saving people. When humans encounter danger in the sea, dolphins will help humans in time, and sometimes they will challenge fierce sharks in order to save people. So, why do dolphins save people?
Some scientists believe that dolphins may be saved by their "caring nature" for their children.
Dolphins are mammals that breathe through their lungs, and when baby dolphins encounter an accident, the mother dolphins will use their mouths to lift them out of the water to allow them to breathe. So when dolphins encounter a drowning person, nature prompts them to push them out of the water, thus saving the drowning person.
<h1 class="pgc-h-arrow-right" data-track="11" > dolphins sleep? </h1>
Do you know? Dolphins sleep "turning a blind eye"!
Because the two hemispheres of their brains are alternately sleeping, when the right hemisphere is in a "sleep" state, the left cerebral hemisphere is in a "excited" state, and after a period of time, it will rotate left and right. During this time, they can swim continuously, as if they were not asleep.
<h1 class="pgc-h-arrow-right" data-track="14" How do > dolphins determine the location of their prey? </h1>
Seeing by the eyes? Ears listening? Still is......?
In fact, they rely on sound waves for "echo localization".
First they emit sound waves that resemble "ticking", and when these waves hit an obstacle, they bounce back. They then use the ear behind the eye to receive the echo, constructing an audio image based on these feedback signals to determine what the object looks like and where it is.
