Ever wondered how the "Sea Cow" made it to the Philippine archipelago? Unlike the Austronesian people who migrated from the north (Taiwan), the Dugong is a southern traveler with an epic history spanning 50 million years.
The story begins in the Tethys Sea (the ancient body of water between Africa and Europe) about 50 million years ago. While some of their cousins headed west to become Manatees in the Americas, the ancestors of the Dugong headed east along the coastlines of Africa and India.
The Dugongs used the "Sulawesi-Sulu Bridge." Because they are benthic (bottom) feeders, they followed the shallow continental shelves of Indonesia and Australia, "island hopping" through the Sulu Archipelago and the Palawan chain. Currently, Australia holds the largest number of Dugongs in the world at around 160,000.
As the Philippine islands rose and seagrass meadows stabilized thousands of years ago, the Dugong found its version of paradise. They moved northward, following the clear, shallow waters along the West Philippine Sea until they discovered the sheltered, nutrient-rich "pocket coves" of the Bataan Peninsula.
