? The dolphin belongs to the mammal, that is, a relatively advanced animal. Like other animals, dolphins have many sensory organs that can perceive objects around them, such as vision, hearing, touch and so on. Among these sensory organs, the most important one is hearing. In fact, the dolphin's vision is not good, when swimming in the ocean, it mainly relies on hearing to identify the direction. The structure of the dolphin's head is quite special, just like a special sonar system.
Dolphins rely on this system to emit ultrasonic waves, and when these sound waves encounter objects around them, they will reflect back and be received by dolphins. Dolphins will know what objects around them need attention, can perceive the distance and shape of these objects, and identify the direction and so on. When dolphins swim, this function can play an important role, so that dolphins do not get lost in the vast sea.
? As mentioned above, dolphins rely on echoes to locate. When dolphins swim in the ocean, they will constantly emit ultrasonic waves, which will be reflected back when they encounter solid materials around them. This signal will be received by dolphins again, and dolphins can locate accordingly. When researchers studied this ability in dolphins, they first blindfolded the dolphins to avoid visual interference. Experiments have shown that dolphins can also locate and perceive objects around them without vision. It can be seen that the echolocation ability of dolphins is very strong, which is more powerful than their visual function.
