Identification Tips

1. 1

   Disc Shape

   Look for a diamond-shaped disc that is slightly wider than it is long, with a broadly rounded snout.

2. 2

   Tail Spines

   Note the presence of one or more venomous serrated spines on the dorsal surface of the tail, typically located about halfway down its length.

3. 3

   Coloration

   Observe the light brown to olive-gray dorsal coloration, often with subtle mottling, and a white ventral surface.

4. 4

   Habitat

   Its presence in freshwater or highly brackish environments is a strong indicator, as few other ray species tolerate such conditions.
