Behaviour - Intelligence and Language: "Dolphins have a language to communicate with one another. It differs a lot from that of humans.

For an example, we use facial expressions as a way of communicating. When we are angry, this can be read from our facial or body expressions like clenching fists or frowning. When we are happy we smile, and sometimes we will raise our hands to show extreme happiness.

Dolphins cannot do all these. They can't make facial expressions and they can't do many actions with its body. The spoken language is another thing which dolphins can't use. They don't have vocal chords and the only body part that can create any sound is the blowhole. This makes it very difficult to communicate with one another. Researchers have tried deciphering the sounds of dolphins but nothing really significant has come out of their research.

Another example of a shaky communication is between the dog and the cat. They have the same ways of communicating but not the same language. When for example the dog wags its tail, it means that it is happy. When the cat uses this same signal, it is an indication of hostility. This is the reason that the communication between a dog and a cat falters.

There are two causes for bad communication. Firstly it is the different ways of communicating and secondly the different language. For the communication between people and dolphins, both factors clash. In the first case it is the different communicational methods which cause the clash. Secondly, it is the constant facial expression of dolphins and the incomprehensible sounds that a dolphin produces, of which humans can decipher almost nothing.

The only communication that exists is the movements that we make. This is very helpful in dolphinariums. When an attender turns, the dolphin has to follow. When the attender claps his hands, the dolphin will perform another trick. This is the only effective way of communication so far."
