The Santa Cruz pupfish exhibited sexual dimorphism in size, with males averaging 37mm (1.46in) in length and females averaging 32mm (1.26in) in length.[2] Coloration in breeding males was dark green to black with alternating stripes of light and dark. Female and non-breeding males were reported to have clear fins except for a black dorsal fin. C. arcuatus is differentiated from other Cyprinodon species by a highly convex dorsal body and concave post-dorsal body, as well a lack of orange or yellow in breeding males' fins.
