More about the Whale Sharks in Donsol

The Whale Shark, Rhincodon Typus, is included in the list of endangered species. There are only about 1000 identified Whale Sharks worldwide. Despite the fact that studies trace the history of the Whale Shark to be 245-265 million years back to the Jurassic and Cretaceous periods,  the enormity of these fish, and the fact that they swim at the ocean surface, the first known Whale Shark to man was discovered in 1828.

As the study of the Whale Shark developed, it is said that the largest annual congregation of the Whale Sharks is in Donsol, Philippines from December to May. These so-called gentle giants are migratory animals, found in warm tropical waters as they follow their food supply. They migrate to Donsol in vast numbers to take advantage of the dense food concentration of plankton and krill which is brought about by the current patterns, water temperature, and the general health of the sea.

With the discovery of the immense number of Whale Shark in Donsol and the promotion of eco-tourism in the area, efforts for the preservation of the Whale Shark has been heightened. Scientists and conservationists have also migrated to Donsol to further study these animals. By using tracking devices and photo identification, it is hoped that the mystery of these great gentle giants will be soon discovered.

In Donsol waters, typical sightings of whale sharks are between 4-12 meters in length with distinctive characteristics that include a broad, flat head, 3 prominent ridges on the upper flank, a checkerboard pattern of white spots and stripes on its blue-gray-brown-skin.

Their huge mouth (up to 2m across) is lined with thousands of tiny teeth, which is neither used for chewing nor biting. Large volumes of water are sucked into the mouth where the food is retained in the gill rakers Water is eventually released through their gill slits. Whale Sharks are rare and amazing creatures. Swimming with them is an adventure of gigantic proportions.
