Manila: The sighting of a pod of about 50 melon-headed whales in the municipal waters of San Jose, Occidental Mindoro has given marine conservationists hope as the rare encounter is seen as a sign of a productive and healthy marine ecosystem. The Department of Environment and Natural Resources (DENR) - Mimaropa reported the sighting of the melon-headed whales (Peponocephala electra) on July 19 by members of the community-based TAYUM Tamaraw SJ Freedivers while traveling to a dive site near Ambulong Island.
According to Philippines News Agency, initially mistaken for dolphins because of their similar appearance and schooling behavior, the animals were later identified by the Philippine Marine Mammal Stranding Network (PMMSN) as melon-headed whales. The pod was observed calmly resting at the water's surface, with several individuals occasionally breaching before continuing their movement toward deeper offshore waters.
The PMMSN highlighted that melon-headed whales, an oceanic member of the dolphin family, normally inhabit deep tropical and subtropical waters, and are seldom seen near coastal waters. While the sighting itself was unusual, marine experts say its significance goes beyond the rarity of the species.
The DENR Community Environment and Natural Resources Office (CENRO) - San Jose noted that melon-headed whales are highly social animals that usually travel in large pods. Their presence is widely recognized as an indicator of productive and relatively healthy marine habitats capable of supporting diverse marine life.
The DENR emphasized that the recent encounter underscores the ecological importance of Occidental Mindoro's marine environment and highlights the need to continue protecting the province's coastal and offshore ecosystems. "Healthy oceans not only support wildlife but also sustain fisheries, ecotourism, and the livelihoods of coastal communities," it added.
Following the sighting, CENRO-San Jose reminded boat operators, divers, fishers, as well as the public, to observe responsible wildlife viewing practices whenever marine mammals are encountered. It urged the public to maintain a safe distance from marine mammals, minimize noise, avoid sudden changes in speed or direction, and refrain from feeding or disturbing the animals.
"Responsible interactions help ensure the welfare of these species while allowing future generations to continue appreciating the Philippines' remarkable marine biodiversity," it stated. The DENR said the rare appearance of the melon-headed whale pod serves as both a reminder of the biodiversity found in Philippine waters and the value of sustained conservation efforts to keep marine ecosystems healthy.
