Locally known as rumbà-rumbà, the Gray’s spinner dolphin (Stenella longirostris) is one of the 26 species of cetaceans in the Philippines. They can be seen spinning high in the air (hence its common name) or riding the bow waves of boats. Also known as long-beaked or long-snouted dolphins, they usually feed at night on small fish and squid. According to noted dolphin expert Kenneth S. Norris, “divergence zones at current margins and current ridges which both concentrate food organisms are heavily frequented by dolphins.” They can dive up to 984 feet or 300 meters to get food.
