The Haller's Stingray is found within the Eastern Pacific from Humboldt Bay in northern California south to the Gulf of California and Panama City, Panama. Most abundant in southern California and northern Baja California, Mexico.


Round rays prefer sandy or muddy bottoms, but are occasionally found in rocky reef areas. They most commonly inhabit water depths from intertidal to less than 15 m (50 ft) in depth, but may also be found in water as deep as 91 m (300 ft). It is not unusual to find them in greater numbers at estuary mouths and shallow bays during breeding and pupping times of the year (April to September). Sloughs and beaches are other favorite areas.


As its common name implies, this ray’s smooth body or disc is nearly round. It does not have a dorsal fin. Its sturdy tail is less than half the length of its body and ends in a true caudal fin, unlike the thin whip-like tails of other stingrays that usually lack a caudal fin. The eyes and spiracles are on top of the head and the mouth, nostrils, and gill slits are on the ventral side. The sting is located on top of the tail about half way back from the base of the tail. An average sized ray usually has a spine that is 2.5-3.8 cm (1-1.5 in) in length.


Round rays vary in color from tan to brown to gray and from plain to spotted or mottled with varying pattern shades giving them a dappled appearance. The dappling is diffuse in most round rays, but in some, the patterns are well defined. The underside is a solid whitish or light yellow color.


The largest round ray reported had a total length of 58.0 cm (22.8 in). Maximum reported weight is approximately 1.3 kg (3 lb). Most round rays are much smaller than this and more commonly seen with a disc diameter of 25.4 cm (10 in) or less.


This species feeds mostly during the day, relying on sight and smell to locate prey items. The mouth and large fins are used to remove bottom sediment when exposing buried food. The diet consists primarily of bottom dwelling invertebrates such as worms, shrimp, amphipods, clams and other small mollusks, and small fishes. Although predominantly bottom feeders, they have been observed in the upper water column preying on small fishes.
