This order contains dolphins and whales. These are marine mammals.
In Singapore, 13 species have been recorded. The one most likely encountered are the uncommon Indo-Pacific Bottlenose and Humpback Dolphins. These are followed by the rare Finless Porpoise and Irrawaddy Dolphins1. The False Killer Whale is even rarer with only one found stranded at Tuas in 19942. In 2015. Singapore had its first record of Sperm Whale, albeit a dead one off Jurong Island3. The rest are possible in Singapore water but need to be confirmed4,5.

The Indo-Pacific Humpback Dolphin (Sousa chinensis) is uncommon and can sometimes be seen in our Southern waters. It is also called Pink Dolphin due to its pale coloration. It has a distinctive hump on the back and the dorsal fin is much shorter than the bottlenose dolphins'. The rest of the cetaceans are extremely rare.
