Family Potamotrygonidae

Distribution. Upper Seletar Reservoir ( Ng et al., 2009; Chua G, 2010; Ng HH & Tan HH, 2010; Ho et al., 2016); Lower Peirce Reservoir ( Lai, 2015; Ho et al., 2016); Banir stream [direct link to Lower Seletar Reservoir] ( Tan & Zeng, 2015); Lower Seletar Reservoir ( Ho et al., 2016).

Remarks. Recent observations indicate a breeding population at Lower Peirce Reservoir, where up to six juveniles were sighted at night in shallow water adjacent to a boardwalk (Zhou H, pers. obs., August 2016). This stingray’s diet includes fishes and aquatic macroinvertebrates, including freshwater gastropods, crustaceans, and insect larvae ( Tan & Tan, 2018; Kwik et al., in prep.).
