The cockscomb oyster, ''Lopha cristagalli'', is a species of marine bivalve molluscs in the family Ostreidae. ==Description== The cockscomb oyster has a shell reaching a maximum diameter of about 20.5 cm, commonly 10 cm. It has a variable coloration, dark to light purple, and it is a thick, strongly ribbed, and slightly inequivalve shell. The shell inside is porcelaneous, usually purplish-brown or whitish in colour. The margins of the valves have a characteristic zig-zag pattern. The surfaces of both valves have many small, low, and rounded protuberances. These molluscs are stationary epifaunal suspension feeders, as they feed filtering sea water to extract the nutrients.
