The habitat of each dolphin depends on the type, size, shape, weight, and length, temperature of the water and food source. Dolphins live in all oceans of the planet and even in some important rivers. While not all species of dolphins live everywhere, there is a species for each environment. Specifically one of the best known species, the bottle-nose dolphin lives in every ocean of the world except the Arctic and the Antarctic oceans. The Atlantic spotted dolphin, lives all over the tropical and warm temperate areas of the Atlantic Ocean avoiding the Arctic and Antarctic regions. Species like the Pink Dolphin however lives in the places like the Amazon River. Habitat range and migration for dolphins is highly dependent on the water depth, sea surface temperature, distance from shore, and available food.
