The senses of the dolphin are all valuable tools to analyze its environment and communicate.

Olfaction – Smell: the olfactory system has practically disappeared in the dolphin. The sense of smell is almost non-existent. This could be explained by the fact that their prey has no odor.

Taste: on the other hand, the taste perception is very developed in the dolphin, which allows it to collect information on the quality of the water, on the prey that surround it, on the sexual receptivity of its congeners, on Alarm signals, etc.

Touch: the skin of the dolphin is very sensitive, it plays an important role in the communication and cohesion of the group. Depending on the location sought and its vigor, contact may mean affiliation or indicate aggression or anger. Touching is an integral part of the daily life of dolphins.

The view: the dolphin has an excellent view. He sees both under water and in the air. Thus, it is not uncommon to see the dolphins standing vertically in the water, head out in position „espionage“.

Hearing: the sea is a world of noises and to cope with it, the dolphin is very well armed: hearing is the most developed and specialized sense in the dolphin. In order to locate the origin of the sounds, the two ears are isolated from each other and the skull, which acts as an amplifier. Hearing is directly related to the sixth sense of the dolphins which is echolocation. Also in order to preserve the hydrodynamism, the ears of the cetaceans are not apparent, even the orifice is reduced to a tiny hole.

The echolocation: the dolphin is endowed with a particular attribute: the sonar which allows him to be guided by an echolocation system. It was during the Second World War that we realized the capacity of cetaceans to emit ultrasounds. Indeed, the pilots of the American submarines did not understand why their sonars were disturbed by ultrasonic emissions not coming from the enemy. The dolphins were, in fact, responsible for this phenomenon. The sonar how does it work? The dolphin emits a beam of sound waves at high frequencies in the direction of an object, an individual, some mass, etc. The waves bounce against this target, then return to the jaw, which serves as a receiving antenna. These waves propagate to the inner ear. From there, the information is transmitted to the brain that analyzes them and develops a mental image.
Thanks to this function (because, beware, the sonar is not an organ!) The dolphins would be able to perceive the inside of the body of their congeners and that of other individuals, including men …
