Bottlenose dolphins have a broad distribution that includes most of the tropical, subtropical and temperate parts of the ocean where there are several kinds of habitats.
Dolphins are not frequent victims of any predator in the ocean due to their sociability and intelligence, but killer whales and some large sharks are their main natural threat.
Each Killer whale population has a different niche in their habitat and consume different resources, however all are the apex predators of the place they live.
Free Dolphins have hundreds of miles to swim in the ocean, while they can not do it in captivity.
The Fraser’s dolphin (Lagenodelphis hosei) was identified as species en the 1970’s although it has a wide distribution all over the tropical areas of the ocean.
