Fish Hook is found in specimen beds between the café and solar field, and around the wildflower field. This barrel, from the same genus as the Blue Barrel, is easy to distinguish by the variety of its spines’ shapes. The name comes from large, flat spines that appear on this cactus and curve to form a hook. These central spines have been used by the local Seri people as fish hooks, and all parts of the cactus have been used for food or tools.
Flowers range from yellow to orange, followed by yellow ovoid fruit.
Distribution includes central and southern Arizona, New Mexico, southwestern Texas; and Chihuahua, Sonora, and Sinaloa in northern Mexico.
