Although dolphins inhabit every ocean of the planet including some rivers and other ecosystems, the common bottlenose dolphin can be found in the warmer oceanic regions specifically in temperate, subtropical, and tropical oceans around the world. [54] [55] The global population has been estimated at 600,000. [56]
It contains the northern right whale dolphin (Lissodelphis borealis) and the southern right whale dolphin (Lissodelphis peronii). These cetaceans are predominantly black, white beneath, and some of the few without a dorsal fin or ridge. They are smaller members of the delphinid family, oceanic dolphins, and very slender.
