Info
Gibbula ardens is a beautifully ornamented shell snail that is very often observed in association with the seagrass Posidonia oceanica.
Gibbula ardens has a deep, large, circular umbilicus and a wide aperture; its sculpture is variable and consists of numerous concentric grooves.
The columella features a basal fold.
Gibbula ardens differs from Gibbula umbilicata in its large aperture and basal fold, and from Gibbula albida in its large umbilicus.
The snail has a relatively short lifespan of about one year and grows very rapidly, especially in the first few months after settlement.
The species is considered semelparous.
At first glance at the photo by Sylvain Le Bris, one might get the impression that the snail is feeding on a captured brittle star; however, what appear to be the brittle star’s arms are actually two large tentacles and three pairs of lateral tentacles—the epipodial tentacles, which serve as additional, smaller sensory tentacles.
