The Mekong dolphin (Irrawady dolphin)

An Irrawaddy dolphin, also known as the Mekong dolphin, swims in the river at Kampi village in Kratie province, 230 km (143 miles) northeast of Cambodia, March 25, 2007. Cambodia's rare Mekong dolphin is making a tentative comeback from the edge of extinction after net fishing was banned in its main habitat, Cambodian and World Wildlife Fund officials said earlier this month.
