Dolphins and porpoises are carnivores -- most eat fishes and/or squids. Different habitats mean different diets; each type of dolphin and porpoise specializes in catching prey that lives in its specific ecosystem. Here are some examples:

Dolphins communicate with whistles and use individual "names" to identify one another. Some research scientists who study dolphin communication think that wild dolphins have special high-pitched calls known as signature whistles that they use to tell pod pals apart. Each dolphin chooses its own signature whistle, usually by its first birthday. This name stays the same for at least ten more years.

Dolphins are often regarded as one of Earth’s most intelligent species. Numerous stories are told of dolphins protecting shipwrecked sailors against sharks by swimming circles around them. In many cultures, spotting dolphins during a sea voyage is considered a good omen. Swimming with dolphins is the closest encounter one can experience with these fascinating creatures. On your next trip to Great Exuma Bahamas, be sure to consider this once in a lifetime opportunity, an adventure that will create memories you will treasure forever.

Dolphins eat several kinds of fish and squid. The composition of the diet depends very much on what is available in the area they live in and ... on the season. The amount of fish they eat depends on the fish species they are feeding on: mackerel and herring have a very high fat content and consequently have a high caloric value, whereas squid has a very low caloric value, so to get the same energy intake (calories) they will need to eat much more if they feed on squid than if they feed on mackerel or herring. On average an adult Dolphin will eat 4-9% of its body weight in fish per day.

Despite the historic practice of lumping the entire Delphinus genus into a single species, these widely distributed dolphins exhibit a wide variety of size, shape and colour. Indeed over the past few decades over 20 distinct species in the genus have been proposed. Scientists in California in the 1960s concluded that there were two species - the long-beaked and short-beaked. This analysis was essentially confirmed by a more in-depth genetic study in the 1990s. This study ... suggested that a third species (D. tropicalis, common name usually Arabian Common Dolphin), characterized by an extremely long and thin beak and found in the Red Sea and Indian Ocean, might be distinguished from the long-beaked species.
