People in Muscat, Oman, saw pink dolphins swim close to the shore in October, with darker companions nearby. Videos of the encounter spread online after beachgoers watched the animals surface in the waters off Oman’s coast.
The sighting stands out because the pink color alone does not settle the species. Marine experts have not identified the dolphin caught on camera, even though pink dolphins are often associated with the Amazon River dolphin in South America.
Muscat footage drew attention
The footage showed more than one dolphin moving together, a detail that makes the scene easier to misread at a glance. A pale animal can suggest a familiar label, but the camera only captured appearance and movement, not the markers needed for a species call.
That is why the better comparison is not to one famous pink dolphin, but to a range of dolphins that can lighten with age. Some Indo-Pacific humpback dolphins found in coastal waters across parts of Asia can develop pale or pinkish skin as they grow older, and adults in populations around China and Hong Kong are particularly known for that appearance.
Species clues from color
The color change is not just cosmetic. As the skin becomes paler, blood vessels close to the surface can show through and create a pink flush, and increased blood flow near the skin helps dolphins release excess body heat. Physical activity can make that color more noticeable, which is one reason a moving animal can look more vivid on video than it would at rest.
That mechanism still does not identify the animal in Oman. Scientists have not established whether the same process explains the dolphin filmed off the coast, and another possibility raised in reports is Risso's dolphin, Grampus griseus. A humpback dolphin remains another option, but neither identification has been established.
International Whaling Commission note
The International Whaling Commission says Indian Ocean humpback dolphins generally remain lead-grey throughout their lives, which complicates a quick assumption based on color alone. That leaves the Oman sighting in a narrow space between what the footage shows and what it cannot prove.
For beachgoers in Muscat, the practical takeaway is simple: the animal was real, the video spread fast, and the name attached to it still hangs on a visual guess. What species was the pink-looking dolphin off Oman’s coast? That is the part the footage has not answered yet.
