Pastinachus gracilicaudus, the narrow cowtail ray, is a type of cowtail ray patchily found in Indo-Malay Archipelago.[2][1] It lives in the continental insular shelves of up to 60 m depth.[1]
The narrow cowtail ray possesses several characteristics, including rounded snout, 120-122 pectoral fin radials, 37-40 monospondylous vertebral centra, and the presence of 2 large midscapular pearl thorns.[2] It can reach the maximum size of 83 cm disc width.[1] Its reproduction is believed to be viviparous and the birth-size might be 19 - 26 cm disc width.[1]
Habitat & distribution
This demersal species is usually found on the coastal regions at the depths of 1 - 60 m.[2][1] Its exact habitat is quite patchy, being believed to be both Indonesian and Malaysian Borneo, Sumatra, Java, and Malay Peninsula.[2] Several possible threats that directly affect this species are sea pollution, climate change, and over-fishing.[1]
