The Pink river dolphins are freshwater dolphins who live in the Amazon river and the Orinoco River.
Dolphins live in all oceans of the planet and even in some important rivers.
The Chinese white dolphin can be found anywhere in the Indian and Pacific oceans off the coast of south China.
Bottlenose dolphins do not have a migration pattern defined for winter months.
While bottlenose dolphins do not migrate in summer, they tend to move locations due to the water temperatures.
