common name the true conchs, is ataxonomic family of medium-sized to very large seasnail s with an operculum. These are marinegastropod mollusk s in the orderSorbeoconcha .The family Strombidae includes the true
conch s,tibia s, and their allies. Many more species existed in the geological past than are now extant.Distribution
Most of the living species of strombids occur in the
Indo-Pacific region.Six species of strombids are found in the wider
Caribbean region, and all of them are in the genus "Strombus".Description and life habits
Strombids have long eye stalks, a long and narrow aperture, and a
siphonal canal . The shell margin has an indentation near the anterior end which accommodates one of the eye stalks. This indentation is called a strombid or 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).
The species in this family grow a flared lip upon reaching sexual maturity, and they lay eggs in long, gelatinous strands.
