Concern grows over future of Thailand's endangered sea cows

According to the Institute for Research and Development of Marine and Coastal Resources, 129 sea cows lived in the Andaman Sea in 2010. However, as up to 15 sea cow deaths are reported each year, authorities on Koh Libong in Trang province are worried that the endangered marine mammals will eventually vanish from its waters.
