Echis carinatus astolae, known as the Astola saw-scaled viper, is a viper subspecies endemic to Astola Island off the coast of Pakistan. Like all other vipers, it is venomous.
The color pattern consists of a series of dark brown dorsal blotches on a whitish background. Laterally, there are 1-3 rows of dark brown spots with no light arcs. On the head, there is a three-pronged, light mark directed towards the snout. From the temporals, a light lateral line meets at the frontal region, with a branch to the snout.
Echis carinatus astolae is found only on Astola Island, off the coast of Makran, Pakistan.
