The pink color is not necessarily the result of special pigmentation. In certain species of marine dolphins, including the Indo-Pacific humpback dolphin, the hue may be related to blood vessels visible through the skin. However, at this stage no definitive confirmation has been published identifying the dolphin filmed in Oman or explaining its color.
Following a report published in the Omani newspaper Al-Shabiba, writer Abbas Al-Zadjali claimed that the dolphins in the original video actually appear to be Risso's dolphins, whose color may lighten with age.
The report also drew interest because pink dolphins are known to many primarily from the Amazon in South America.
The coasts of Oman, and especially the Muscat area, lie along the shores of the Gulf of Oman and offer marine habitats for a variety of animals.
