The dolphin fish (Coryphaena hippurus) is also called the mahimahi, coryphene, or dorado. They have slim aero dynamic bodies and a short beak with conical-shaped teeth, which helps these dolphins find and capture various prey. It is on the top of the dolphin; they only have one dorsal fin that gives them stability when swimming, preventing them from spinning involuntarily in the water.

The long-beaked common dolphin is medium-sized, but smaller than the more popular bottlenose dolphin. In December 2015, biologists and researchers in the US and UK captured an image of a submerged researcher using only the echolocation beam from a dolphin. It moves from top to bottom and not from side to side as in the case of fish. The neck is rather short because the seven cervical vertebrae are fused together. Bottlenosed dolphins have a fusiform body that lacks many external characteristics of terrestrial mammals, including hair, external ears and hind limbs. They are also kept in some facilities for research. The blowhole allows a dolphin to come up to the surface, easily take in air, and continue swimming. The bottlenose dolphin (like the beluga) has more flexibility in its neck than other oceanic dolphins, because 5 of the 7 neck vertebrae are not fused together as in the other oceanic dolphins.

In general, bottlenose dolphins are 2 to 3.9 m (6.6 to 12.8 ft.). Beneath the skin, there is a thick layer of fat that dolphins use as an energy reserve in periods of food shortage, as an insulation to prevent heat loss in cold environments and as a resource that helps maintain the hydrodynamic shape of their body. They also have a large brain, the second largest for mammals in comparison to their body size, only after humans. Dolphins have a streamlined body designed to swim very fast, even for extended periods of time. However, not all species have the same color pattern described above.
