Pteropurpura trialata, the three-winged murex, is a medium-sized species of predatory sea snail, a marine gastropod mollusk in the family Muricidae, the rock snails or murex snails. It is native to the eastern Pacific Ocean.
The shell can grow to a length of 93 mm (3.7 in). [2] It is fusiform and fairly thick, with a spire angle of 40-42°. The protoconch has one and a half smooth, conical whorls, while the teleoconch has eight whorls which are moderately convex. Each whorl has three elaborately sculptured varices (thickened protruding ridges) with nine to twelve fluted cords extending onto the varices. [3]
The three-winged murex occurs in the semi-tropical eastern Pacific Ocean, its range extending from northern California, through Baja California to Mexico. [2]
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With over 1,700 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized. Numerous subfamilies are recognized, although experts disagree about the subfamily divisions and the definitions of the genera. Many muricids have unusual shells which are considered attractive by shell collectors and by interior designers.
A varix is an anatomical feature of the shell of certain sea snails, marine gastropod molluscs. Gastropods whose shells have varices are primarily families and species within the taxonomic groups Littorinimorpha and Neogastropoda.
