Comments: Previous occurrence in map (Ref. 1394, p. 193) is confirmed by Ref. 1522. Sighted in Malampaya Sound in Northern Palawan (Ref. 1394); Reported as Neophocaena phocaenoides phocaenoides in Palawan, Turtle Islands, Visayan Islands and Mindanao (Ref. 1522). Occurrence in Palawan is just suggested. Sighting in other areas still needs further verification but for now it can be considered as locally extirpated in the Philippines (Ref. 91365). Known size is up to 182.88 cm (Ref. 936). C: Refs. 1522, 936, 84562; M: Ref. 1394.

Found in both fresh and marine. Feeds on small fishes, squids and shrimps; also ingests some plant material including leaves and rice (Ref. 1394). In 2006, a population survey was able to record a total of 300 individuals of Neophocaena phocaenoides asiaeorientalis, as experts provide an estimate of 1,400 individuals based on the said survey. This is considered a 50% decline from the survey done in 1991 (Ref. 85336). Found in tropical to warm temperate coastal waters, i.e., shallow bays, mangrove swamps, estuaries and large rivers, but mainly prefers estuarine waters (Ref. 81021). Occurs singly, in pairs, or in small groups of up to 12 individuals. Not as showy as other dolphins; though, they are occasionally seen breaking the surface in calm seas (Ref. 801). Feeds on small fishes, squids and shrimps; also ingests some plant materials including leaves and rice (Ref. 1394).
