The Chilean round stingray (Urobatis marmoratus), is a species of round ray, family Urolophidae.[2] Virtually nothing is known about it, as it is only known from a single specimen described by Rodolfo Amando Philippi in 1893. The specimen measured 38.5 cm long and was collected off Quintero, Chile.[1] It had the nearly circular pectoral fin disc typical of the round rays, with the front margins straight. The distance between the eyes was more than two-thirds the distance between the eyes and the tip of the snout. The body was very thick for a ray, and completely smooth. The tail was shorter than the length of the disc. The coloration was distinctive, consisting of numerous small white spots on a dark background. It is likely benthic.[3]
