Forty species of dolphins live in varied climates, from the arctic, which is inhabited by killer whales, to the Caribbean, which is preferred by bottlenose dolphins. Even the Amazon River basin is home to several dolphins, including the endangered finless porpoise, according to Whale Facts.

Dolphins do well in differing climates due to adaptations. Tucuxi dolphins thrive in salt and fresh water along the eastern coastlines of South and Central America. Orca whales have blubber to insulate their bodies from arctic waters, and dolphins that prefer plankton swim in warm and shallow coastal waters. The Ganges River dolphin has a long, narrow beak that is perfectly suited for digging in mud banks and small crevices for food.
