- Shells are ovate (egg-shaped), smooth and highly polished, white or brightly colored,
and they always have prominent columellar folds. The spire is usually rounded off and
short, or sunken below the enameled surface. Much like the cowries
or the ovulas, the mantle flaps cover the shell,
protecting its high polish. Most species are less than 2.0 cm, although a few larger
species from West Africa may exceed 2 in (5 cm) in size (Keen, 1958).
- The Marginellidae are generally tropical and live in sand, under rocks or in algae beds.
They are abundant mainly in West African, Caribbean, and
Western Pacific waters. Most are believed to prey on other molluscs. However, Orlin (2007) has reported direct observations by several authors who directly observed certain Marginellidae species to have attached and directly sucked the blood of specific fish species.
