Irrawaddy dolphin

The snubfin dolphin is a rare marine mammal with a rounded head and no beak, found in coastal waters and rivers of Southeast Asia and northern Australia. It was only recognized as a separate species from the Irrawaddy dolphin in 2005. Its slate-blue to gray coloring helps it blend into the murky waters where it lives.

• Shares coastal waters and rivers with the similar-looking Irrawaddy dolphin.
• Its blue-gray color camouflages it in shallow, silty habitats.
• Was officially classified as its own species less than 20 years ago.
