* Coastal waters: This includes areas close to the shoreline, such as bays, estuaries, and lagoons.
* Open ocean: This includes the vast expanse of the ocean far from land.
* Deep ocean: Some species of dolphins can dive to depths of over 1,000 meters.
* Tropical and temperate waters: Dolphins are found in both warm and cool waters, but are more common in tropical and subtropical regions.
It's important to note that different species of dolphins have different habitat preferences. For example, some species are found only in coastal areas, while others prefer the open ocean.
