Dolphins have been interacting with humans for as long as we have known of their existence. During this time, their more dangerous predator and the only one that have dramatically reduced dolphin population is the human. Even though we all agree that Dolphins are wonderful creatures that seem to be extremely intelligent and friendly, we still are a huge threat for dolphins.Dolphins often leap above the water surface, sometimes performing acrobatic figures (e.g. the spinner dolphin). This and other behaviour is interpreted as playing. They are capable of diving up to 260 m deep and 15 min long, but rarely stay underwater longer than few minutes. Frequently dolphins will accompany boats, riding the bow waves. They are also famous for their willingness to occasionally approach humans and interact with them in the water. In return, in some cultures like in Ancient Greece they were treated with welcome; a ship spotting dolphins riding in their wake was considered a good omen for a smooth voyage.
Dolphins are predators, chasing their prey at high speed. The dentition is adapted to the animals they hunt: Species with long beaks and many teeth forage on fish, whereas short beaks and lesser tooth count are linked to catching squid. Some dolphins may take crustaceans. Usually, the prey is swallowed as a whole. The bigger species are capable of eating marine mammals, especially the orca, which kills even large whales.
