One of the best examples is the difference between a dolphinfish and a dolphin. Dolphins are mammals and breathe air with lungs just like humans. There are many different dolphins species, including endangered river species, but all of them are in the same animal family (Delphinidae).
The other three species -- the striped dolphin, pantropical spotted dolphin and Atlantic spotted dolphin -- are named for their distinctive body markings. A Touch of White Five of the six dolphin species in genus Lagenorhynchus occur in the Atlantic Ocean, where they inhabit polar to temperate waters. Often called white-sided dolphins, species of this genus have a defining short beak. The white-beaked dolphin, the largest species, is found in subpolar waters in the northern Atlantic. The Atlantic white-sided dolphin also inhabits the northern Atlantic Ocean but in temperate waters. Also in this genus are dusky dolphins, named for their dark backs. They are found along the Atlantic coast of South Africa and around the Falkland Islands of South America, where their range overlaps with that of Peale's dolphins, another Lagenorhynchus species.
