Body laterally compressed. Silvery, often with yellow wash over uppper head and back (not diagnostic as many other Porgies may have this too). Blueish saucer-shaped line below eye (similar on some other Porgies). Small blueish blotch at upper base of pectoral fin. below eye. Can change colour rapidly and show barred or blotched pattern, especially when feeding on bottom. The cheek area is usually blue with yellow spots; the blue markings on the scales are more linear; no horizontal blue band behind eye (cf Pluma Porgy, C. pennatula).
Adults are frequently found in coral areas, while the young prefer vegetated (e.g. Thalassia), sandy bottoms. Feeds mainly on molluscs, worms, brittle stars, hermit crabs, crabs and sea urchins. They reach a maximum length of 55 cm (22 inches) and weight of 1.4 kg (3 pounds).
Most spawning areas are above sea grass beds. The female discharges a multitude of eggs into the open water to be fertilized by the sperm. When this occurs, the larvae are pelagic.
