Round Stingray Identification Guide

Key identification features

• Nearly circular to oval disc, much rounder than most stingrays
• Small size, typically under 25 cm disc width
• Grey, brown, or greenish upperside, sometimes with faint mottling or small dark spots
• Short, thick tail, noticeably shorter than the disc width, ending without a fin fold
• Single venomous spine positioned roughly midway along the tail

Common look-alikes

• Bat ray is much larger with an angular disc, humped head, and long whip-like tail rather than the round stingray's short one
• Yellow stingray, found in the Atlantic rather than the Pacific, shows a similar round shape but has a bold yellow-and-brown reticulated pattern
• Diamond stingray has a more angular, diamond-shaped disc instead of a true circular outline

Where you'll see one

Common in shallow, warm coastal waters of the eastern Pacific, from central California south to Panama, including sandy bays, estuaries, and surf zones. Round stingrays often bury themselves in sand in very shallow water near shore, sometimes in large seasonal aggregations, making them one of the most frequently encountered stingrays in nearshore Pacific waters.
