Volvarina zonata is a species of small sea snail, a marine gastropod mollusk in the family Marginellidae, the marginellas. This species is found in the Indo-Pacific region, particularly in the warm, tropical waters of the Indian Ocean.
Description & Characteristics
Volvarina zonata is a small, delicate snail with a smooth, glossy shell. The shell is typically white or cream-colored with brown or reddish-brown markings. It is characterized by a distinctive pattern of fine, wavy lines that extend from the apex to the aperture. The shell shape is elongated, somewhat spindle-shaped, with a pointed apex and a narrow opening. The maximum size of the shell is around 10 millimeters.
Habitat and Occurrence
Volvarina zonata is a common inhabitant of shallow, sandy or muddy bottoms in the intertidal and subtidal zones. It can be found at depths ranging from the low tide mark to about 20 meters. This species prefers areas with moderate wave action and plenty of food sources. Its distribution encompasses the warm tropical waters of the Indo-Pacific region, particularly the Indian Ocean, where it is commonly found in various marine zones, including the neritic zone.
Taxonomy
Volvarina zonata belongs to the family Marginellidae, which is part of the order Neogastropoda and the class Gastropoda. The family Marginellidae is a diverse group of marine snails that are characterized by their small, smooth, and often brightly colored shells. The genus Volvarina is a relatively small genus of marginellas that are known for their distinctive shell shapes and markings.
Feeding
Like other marginellas, Volvarina zonata is a carnivorous snail. It feeds on small invertebrates, such as worms and other mollusks, using its radula, a ribbon-like structure with rows of teeth, to scrape food from surfaces. The radula is a powerful tool that allows marginellas to effectively break down their prey and extract nutrients.
