The first sighting of Rough-toothed dolphins in Sarangani Bay was recorded by PAMO-SBPS during its team’s recent marine mammal monitoring in the bay.
The Protected Area Management Ofice (PAMO) of Sarangani Bay Protected Seascape (SBPS) has recorded the first-ever sighting of a pod of 10 to 12 Rough-toothed dolphins (Steno bredanensis) in Sarangani Bay, which is under special government protection to preserve marine riches.
According to a report by the Department of Environment and Natural Resources (DENR) Soccsksargen, the team from PAMO-SBPS, Sarangani Environmental Conservation and Protection Center (ECPC), local government unit of General Santos City, and DENR-12 observed the Rough-toothed dolphins to be feeding on squids coastal waters of Glan, Sarangani Province.
PAMO-SBPS head Joy Ologuin stated that this was the first sighting of this species since 2019, the year when the PAMO-SBPS began recording marine mammals residing in the 215,950-hectare bay.
The Rough-toothed dolphins are usually found in deep warm, tropical, and subtropical water from the western Pacific to the Mediterranean. They usually feed on fish, squid, mollusks, and cephalopods.
The species possesses light grey flanks, with a much darker grey back and dorsal fin. Their common name was based on the ridges on their sharp and serrated teeth, which are unique to this species. They can also grow up to about 2.5 meters in length and weigh about 150 kilograms.
