The Panama Graysby, Cephalopholis panamensis, is a member of the Grouper or Epinephelidae Family, that is also known as the Pacific Graysby and in Mexico as cabrilla enjambre and cabrilla ribera. Globally, there are twenty-six species in the genus Cephalopholis, of which three are found in Mexican waters, two in the Atlantic and one, this species in the Pacific Ocean.
The Panama Graysby is a are dark reddish-brown fish have 9 or 10 dark bands on their bodies, a dark spot behind their eyes, and numerous blue and orange spots on the side of their heads. Their anal fin has 3 spines and 8 rays; the caudal fin base is slender and their caudal fin is rounded; their dorsal fin has 9 spines, the third of which is the longest, a notch, and 14 or 15 rays; and, their pectoral fin has 17 to 18 rays. They are covered with small rough scales.
The Panama Graysby is a common, non-migratory, shy, and secretive fish found within coral and rocky habitat at depths up to 76 m (250 feet). They reach a maximum length of 37 cm (14.6 inches), as documented by a fish that was caught by my long time friend Larry Overman, in coastal waters off Loreto, Baja California Sur, in October 2017. They are voracious ambush predators feeding on small fish and benthic crustaceans. They are protogynous hermaphrodites changing from female to male at mid-life. The males are larger, older, and fewer in number. They have a lifespan of twenty-five years. The Panamic Graysby is poorly studied with very limited information available about their lifestyle and behavioral patterns including specific details on age, growth, longevity, movement patterns, diet, habitat use, and reproduction.
The Panama Graysby is a resident of all Mexican waters of the Pacific Ocean with the exception that they are absent from Magdalena Bay, Baja California Sur, northward along the central and northwest coasts of Baja.
The Panama Graysby is easy to identify and cannot be easily confused with other species.
From a conservation perspective the Panama Graysby is currently considered to be of Least Concern with stable, widely distributed populations. They are small in stature and of limited value to most, however they are retained by subsistence fishermen. When released, they will normally return to the deep on their own.
