Ovatipsa chinensis
A nocturnal cowrie with a bright red mantle and spotted shell.
The Chinese cowrie (*Ovatipsa chinensis*) is a marine gastropod mollusk belonging to the cowry family, Cypraeidae. Its bright red mantle is entirely covered with short, protruding filaments. The shell is smooth and elongated, typically 25 to 50 mm long, with a light brown or yellowish color, clear dots on the upper surface, and a flat white base. In the subspecies *variolaria*, the shell is light brown with faint purple spots along the edges. This species lives in the Indian Ocean and central Pacific Ocean, including the Red Sea, East Africa, Australia, Indonesia, and the Philippines, at depths of 35 to 45 meters in intertidal waters. It is nocturnal, hiding under rocks and in cracks and crevices during the day. Recognized subspecies include *Ovatipsa chinensis amiges*, *O. c. chinensis*, *O. c. somaliana*, *O. c. variolaria*, and *O. c. violacea*.
