As the seas and oceans warm, dolphins are being seen more frequently in colder waters outside their historic ranges. Due to the rapidly rising oceans temperatures, the dolphin’s primary food sources are seeking deeper cooler waters. Scientists are concerned that the dolphins will have difficulty adapting as quickly as necessary to find new feeding grounds to sustain their populations.

Some dolphins that live in areas where rivers and oceans meet, known as brackish waters, are also losing habitat as ocean levels are rising due to global warming.
