Species remains unclear

Marine experts have not yet confirmed the species of the pink-looking dolphin. Pink colouring is most often associated with the Amazon river dolphin (boto), a freshwater species native to the Amazon and Orinoco river systems of South America. However, Indo-Pacific humpback dolphins can also grow paler or develop pinkish tones as they mature. The look can result from blood vessels near the skin becoming visible, and increased blood flow helps these dolphins regulate body temperature.

Risso's dolphin, which accumulates pale scars with age, is also mentioned as a possibility. Albinism and leucism can reduce pigmentation too, but they cannot be diagnosed from colour alone. Lighting and viewing conditions may also affect how colour appears. The International Whaling Commission notes that Indian Ocean humpback dolphins, found in the wider region, generally keep their lead-grey colouring throughout their lives.

Experts say scientific observation and further evidence are needed to determine the species and explain the appearance. People are advised to keep a safe distance from dolphins, avoid touching, feeding or chasing them, and ensure boats do not obstruct their movement.
