Zigzag Oyster

Lopha cristagalli commonly called the ZigZag oyster or the cockscomb oyster, is a species of marine bivalve molluscs in the family Ostreidae.

The cockscomb oyster's shell can reach up to 8 inches in diameter, though it is typically around 4 inches. Its color varies from dark to light purple, featuring a thick, strongly ribbed, and slightly inequivalve structure. The interior of the shell is porcelain-like, often appearing purplish-brown or whitish. The valve margins display a distinctive zig-zag pattern, while the surfaces of both valves are dotted with numerous small, low, rounded bumps. These mollusks are sedentary epifaunal suspension feeders, filtering sea water to extract nutrients.

Juvenile oysters attach themselves to solid surfaces on the seabed. Many possess spines that serve as a defense mechanism against predators—animals that hunt and consume other animals for sustenance. The zigzag oyster, known as a true oyster, is edible and characterized by its robust, thick shell with sharp ridges.

This species is widespread in the Indo-West Pacific, from East Africa, including Madagascar, Mauritius, the Red Sea, Seychelles, and the Persian Gulf, to Micronesia; north to Japan and south to Papua New Guinea and Indonesia. It lives on coral reefs in shallow subtidal waters at depths of 16 to 98 feet.
