Strombidae is a family of gastropods in the Order Sorbeoconcha.
Members of the order Mesogastropoda usually have seven teeth positioned crosswise on the radula and a reproductive organ called a verge. The family Strombidae includes the true conchs, tibias, and their allies. Most are extinct. Of the living strombids, most occur in the Indo-Pacific region. Only six species of strombids are found in the wider Caribbean region, and all of them are in the genus Strombus.
Strombids have long eye stalks, a long and narrow aperture, and a siphonal canal with an indentation near the anterior end called a stromboid notch. Unlike most snails, which glide slowly across the substrate on their foot, strombids have a characteristic leaping motion, using their pointed, sickle-shaped, horny operculum to propel themselves forward in a leaping motion (Parker 1922). They grow a flared lip upon reaching sexual maturity, and they lay eggs in long, gelatinous strands.
