Subspecies coloratus rarely reaches 1 m (3.3 ft) in height but the widest central spines often exceed 5 mm; it occurs in an area to the south of and slightly overlapping that of subspecies gracilis. Subspecies gatesii may reach 1.5 m (4.9 ft) in height, and the central spines are curved but not hooked and only 3 mm wide; it occurs only on the islets and islands in the mouth of Bahia de Los Angeles.
