  Dolphin Information and Interesting Facts about Dolphins
Dolphins are referred to as "toothed whales" or Odontocetes differentiated from Baleen whales which have horny plates connected to their upper jaw.

Bottlenose dolphins can often be found "surfing" on the bow of a boat, this is done for the purpose of "hitching a ride" on the currents pushed forward by the boat and considered to be good luck by boaters around the world.

Most oceanic dolphins spend their lives ranging over vast areas of the open sea, far from land.
Open-ocean dolphins encounter less pollution, but some, such as spotted and spinner dolphins, face another hazard: because many travel with tuna, they are often ensnared in tuna nets, where they drown.
And even if a number of oceanic dolphin populations are threatened, groups of the same species in other areas may remain healthy.

 The Dolphin Institute - Resource Guide
Because of their exceptional hearing capabilities, their echolocation sense, and the importance of sound in the underwater world, all dolphins were thought of as primarily “auditory animals.”; Vision was believed to be not particularly well developed, even in oceanic dolphins, and of secondary importance at best.
For example, as the dolphin swims on its side, the pupil of the downward looking eye, gazing into the dark, may be fully open, while the pupil of the upward looking eye, gazing toward the bright surface, may be tightly constricted.
Dolphins can attend to and interpret human gestures, follow the direction in which a human is pointing, monitor rapidly occurring visual symbols appearing on a television screen and report the occurrence of certain key symbols, and easily recognize the same objects across the senses of vision and echolocation.

The cetaceans (whales, dolphins and porpoises) are descendants of land-living mammals, and remnants of their terrestrial origins can be found in the fact that they must breathe air from the surface; in the bones of their fins, which look like huge, jointed hands; and in the vertical movement of...
Proponents of whale and dolphin intelligence cite the social behaviour of whales and dolphins and their apparent capacity for communication as evidence of a sophisticated intellect, though scientists often carefully point out the difference between the social traits and intelligence of animals, which laymen often confuse.
Given the radically different environment of whales and humans, and the size of whales compared to dolphins or chimpanzees, for instance, it is extremely difficult to test these views experimentally.

The Irrawaddy dolphin species do not ride the waters infront of the bows of boats, but they do have a special relationship with fisherman on the Irrawaddy and Mekong rivers, by driving fish into their nets.

The environmentalists' suit names the National Oceanic and Atmospheric Administration, whose new rule said the encircling fishing practice would no longer disqualify tuna from a "dolphin safe" label as long as independent on-vessel observers certified that no dolphins had been killed or injured during a catch.
William Hogarth, head of the oceanic administration, said there wasn't enough evidence to show that the encircling nets had a significant role in the continued decline of some dolphin species.
Armed with recent footage taken off the Galapagos Islands showing 50 or more dolphins dead or dying in a purse-seine net, the environmental groups say they don't trust the observers, many of whom are pressured by the fishermen.
