Zigzag Cowry

Palmadusta ziczac

Zigzag cowries are small, pyriform shells that generally measure between 15 and 20 millimeters in length, with a maximum size reaching 26 millimeters. Their coloration ranges from light beige to light tan, and they are characterized by three prominent transversal white bands that form a zigzag pattern. The underside of the shell is yellow or orange-brown, marked with small brown spots along the edges. The aperture is orange and features several short teeth. In living specimens, the mantle is orange-red and has white papillae, which aids in their identification in the wild. This species is distributed across the Red Sea and the Indian Ocean, with notable populations in areas such as the Maldives, Seychelles, and the East Coast of South Africa. They are typically found in intertidal zones and prefer depths from 5 to 20 meters, often concealing themselves under coral and rocks in sandy lagoons and coral reefs. Encountering a Zigzag cowry while diving can be rewarding, as they tend to blend into their surroundings, making them somewhat difficult to spot. Zigzag cowries are primarily benthic feeders, consuming small invertebrates. They reproduce through broadcast spawning, where the embryos develop into planktonic larvae before transitioning into adults. Currently, the conservation status of this species is listed as Not Evaluated, indicating that further research is necessary to understand their population trends and potential threats.
