The Philippines, an archipelago nation, is renowned for its exceptional marine biodiversity, and its waters indeed host a significant shark population. This vibrant ecosystem supports a diverse array of shark species, underscoring the rich health of the surrounding seas.
Diverse Shark Species
The waters surrounding the Philippines are home to approximately 200 species of sharks and rays. Among the most prominent are the whale shark, the largest fish globally, which can exceed 12 meters in length and feeds primarily on plankton. Thresher sharks, easily identified by their exceptionally long, whip-like tails that can constitute half their body length, are also found here. These sharks use their tails to stun prey, such as schooling fish, before consuming them.
Various reef sharks, such as the grey and whitetip reef sharks, are common in shallow coral reef environments. Hammerhead sharks, recognized by their distinctive hammer-shaped heads that enhance their sensory capabilities, also inhabit Philippine waters. Tiger sharks, large predators with striped patterns, are considered rare in most areas of the Philippines.
Key Shark Habitats
Sharks congregate in specific areas across the Philippine archipelago, often drawn by abundant food sources, favorable water conditions, or protected breeding grounds. Tubbataha Reefs Natural Park, a UNESCO World Heritage Site in the Sulu Sea, stands out as a premier shark habitat. This large marine protected area, encompassing 1000 square kilometers, boasts remarkably high densities of grey and whitetip reef sharks. Tubbataha also sees whale sharks, tiger sharks, and hammerheads, making it a significant hub for diverse shark species.
Malapascua Island in Cebu is known for its consistent sightings of thresher sharks. These deep-water sharks visit shallower cleaning stations at sites like Monad Shoal and Kimud Shoal, typically in the early morning, to have parasites removed by smaller fish. Donsol in Sorsogon is another renowned location, particularly for whale sharks, which gather there seasonally from November to June to feed on abundant plankton and krill.
Understanding Encounters
Interactions with sharks in the Philippines are generally safe, as most species are not inherently aggressive towards humans. Unprovoked incidents are extremely rare, as sharks typically exhibit cautious behavior and avoid human contact.
When in waters where sharks might be present, adhering to responsible practices can further minimize potential risks. Swimmers, divers, and snorkelers should avoid wearing shiny jewelry, as it can resemble fish scales and attract curious sharks. It is also advisable to avoid swimming or diving at dawn, dusk, or night, as many shark species are more active during these periods. Maintaining a respectful distance from any marine wildlife, including sharks, is important, and provoking or attempting to touch them should always be avoided. Entering the water with open wounds or when bleeding should be avoided, as sharks possess a highly developed sense of smell.
Conservation Initiatives
The Philippines actively engages in shark conservation efforts. Various local and national programs aim to protect shark populations, which play a crucial role as apex predators in maintaining healthy marine ecosystems. By preying on weaker or sick fish, sharks help prevent the spread of disease, contributing to the resilience of coral reef environments.
Marine protected areas (MPAs), such as Tubbataha Reefs Natural Park, are instrumental in providing safe havens for sharks, allowing populations to recover and thrive. The Expanded National Integrated Protected Areas System (E-NIPAS) Act, passed in 2019, strengthens the protection of these vital habitats. Sustainable tourism practices, particularly in areas known for shark encounters like Donsol for whale sharks and Malapascua for thresher sharks, also contribute to conservation by promoting responsible interactions and providing economic incentives for local communities to protect these species. Organizations like the Save Sharks Network Philippines (SSNP) lead awareness campaigns and advocate for legislative measures to ensure the long-term survival of sharks and rays in the archipelago.
