The recent death of one of the remaining six Irrawaddy river dolphins in the Mekong River in Laos highlights the desperate situation for the already critically endangered animal.
Villagers in Cambodia discovered the female dolphin carcass on April 1, according to news reports in Phnom Penh. She was thought to have been one of the oldest and largest dolphins in the region - a trans-boundary river pool, called the Wang Paa Khaa, which straddles Laos and Cambodia; there are an estimated 85 dolphins remaining in all of the Mekong River, says WWF, of which Cambodia is home to the vast majority.
The dolphin is presumed to have died of natural causes based on examination of her body, but her death is a grim confirmation that humans have failed to protect her species.
"This is a very sad time for this dwindling population of dolphins," said Thomas Gray, manager of WWF's Greater Mekong Species Programme, in a WWF statement. "There are now just five dolphins left in Laos and it is another warning that the species is facing the grave risk of extinction from the country, and also throughout the Mekong River."
