• Dolphins are extremely and almost constantly vocal. They are capable of two kinds of sounds. Clicks are used as a form of sonar, in which echoes of sounds from surrounding objects enable the animals to detect it. Dolphins use whistles to communicate a particular emotional state to influence the behavior of other dolphins.

• Dolphin species vary in their degree of curiosity and friendly interaction with humans. Individual dolphins vary to the same degree. Some species are very shy, others will approach humans with great curiosity. If dolphins have spent time in captivity, they can become very used to people touching them, riding along side of them, etc., but they also can become mildly aggressive; nipping, pushing, etc.

We all heard of the famous stories about dolphin rescues where a human is pushed to the safety of the shore by dolphins. Bottle-nose dolphins seem to enjoy pushing items.
