Species of dolphins & Mekong in Kampucheur

Three species of dolphins have been recorded from the lower Mekong in Kampucheur the Irrawaddy Dolphin Orcaella brevirostris (the only species known to occur upstream of Khone Falls), Chinese White Dolphin Sotalia chinensis (rare) and Black Finless Porpoise Neophocaena phocanoides (uncommon). Other wetland mammals known to occur include the Smooth-coated Otter Lutra perspicillata (quite rare) and Fishing Cat Felis viverrina.Although the entire area is known to be very rich in waterbirds, no studies have been carried: out in recent years and no details are available.
