Gibbula multicolor is a species of small sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
Description and Characteristics
Gibbula multicolor is a relatively small snail, reaching a maximum size of around 15 mm in diameter. The shell of this species is typically conical and features a distinctive, colorful pattern of brown and yellow markings, often with a white or cream-colored base. The shell is generally smooth, although it may display faint spiral lines. The aperture of the shell is round and the outer lip is thin and slightly flared.
Habitat and Occurrence
Gibbula multicolor is commonly found in intertidal and shallow subtidal zones, typically inhabiting rocky shores and reefs. It is particularly prevalent in the Mediterranean Sea, where it is often found attached to rocks and seaweed. This species is known to prefer habitats with moderate wave action and good water circulation, making it a characteristic inhabitant of the infralittoral zone, a marine zone extending from the lowest point of the low tide to about 10-15 meters depth.
Taxonomy
Gibbula multicolor is classified within the Class Gastropoda, which encompasses a vast diversity of snails and slugs. Within Gastropoda, it belongs to the Order Trochida, a group that includes a range of top snails characterized by their conical shells and typically herbivorous feeding habits. Gibbula multicolor, like other members of the family Trochidae, is known for its distinctive shell morphology and its close association with rocky shores.
Feeding
Gibbula multicolor is an herbivore, feeding primarily on algae and diatoms found on rocks and seaweeds. It uses its radula, a ribbon-like structure studded with teeth, to scrape off the algae and diatoms from surfaces. The feeding habits of Gibbula multicolor play a crucial role in maintaining the balance of the marine ecosystem, contributing to the diversity and health of the rocky shore habitats it inhabits.
