About Johnrandallia nigrirostris (Gill, 1862)
Johnrandallia nigrirostris (Gill, 1862) has a compressed, silvery-yellow body that reaches a maximum length of 20.3 centimetres (8.0 inches). This species has black bands running along the base of its dorsal fin, as well as black markings on its snout and forehead. It has a small, protractile mouth, with a black, burglar-like mask marking around its eyes, and brush-like teeth. It is superficially similar to Prognathodes carlhubbsi and Prognathodes falcifer, two other species native to the East Pacific. This fish is distributed in the Eastern Pacific, ranging from the Gulf of California to Panama. Its range also includes Cocos Island, Malpelo Island, and the Galápagos Islands, and it has additionally been recorded in Peru. It lives at depths from near the surface down to 40 metres (130 ft), and inhabits coral reefs and rocky areas.
