@juunlor: Pink dolphins are one of the rarest animals in the world. In 2015, Labroots reported that only 14 of these dolphins were known to exist in the world. Pink dolphins, also known as Chinese white dolphins, are white in color but appear pink when they exert energy, such as when swimming and jumping near the surface of the water. This is due to the ventilation of blood and oxygen beneath their skin. Since 2015, the number of pink dolphins has yet to be confirmed with the world wildlife foundation saying that there are only an estimated 2,000 pink dolphins left in the Pearl River Delta (2020).
