About Paratectonatica tigrina (Röding, 1798)
Paratectonatica tigrina is a species of sea snail originally described by Röding in 1798. The shells of this species can reach sizes of 20 to 40 millimeters, or 0.79 to 1.57 inches, with most commonly recorded mature sizes between 28 and 30 millimeters. The shells are pear-shaped and quite thick, with slightly elevated, protruding spires. The surface of the shell is whitish or pale brown, marked with faint brown or yellow trans-spiral lines, as well as small dark brown or black spots. The operculum is white, quite smooth, and typically has yellow and gray patches. The mollusk’s foot is large, whitish, almost translucent, and plain in color. This species is commonly found crawling on sandy bottoms in the mesolittoral zone. Its distribution covers the Red Sea, the Indian Ocean off Madagascar, the Southeast Indian coast, India’s Konkan coast extending to Kerala, Eastern Africa, Southeastern Asia, and Australia. In some countries, primarily Indonesia and Japan, these sea snails are collected for human consumption, and their shells are traded commercially.
