Oxymeris
Oxymeris is a genus of sea snails, marine gastropod mollusks in the family Strombidae, the true conchs. They are commonly known as “olive shells”, and their shells are widely collected for their beauty and interesting patterns.
Characteristics
Oxymeris shells are typically elongated and spindle-shaped, with a pointed apex and a wide, flared aperture. The shell surface can be smooth, ribbed, or ornamented with various patterns. The outer lip of the aperture is often thickened and flared, and the inner lip may have a distinct tooth or ridge. The color of the shell can vary depending on the species, ranging from white and brown to orange and red.
Distribution and Habitat
Oxymeris species are found in tropical and subtropical waters around the world. They prefer shallow, sandy or muddy bottoms, often near coral reefs or seagrass beds. They are typically found in intertidal zones and subtidal depths, with some species inhabiting deeper waters.
Diet and Behavior
Oxymeris snails are herbivores, feeding mainly on algae and detritus. They use their radula, a tongue-like structure with rows of teeth, to scrape food from surfaces. These snails are also known for their "jumping" behavior. When disturbed, they can suddenly extend their foot and propel themselves forward with a swift, leaping motion.
Reproduction
Oxymeris snails are dioecious, meaning they have separate sexes. Females lay egg capsules, often attached to rocks or other hard surfaces. The capsules contain numerous embryos, which develop into young snails over time.
Species
The genus Oxymeris includes several species, including:
- Oxymeris bacillus (Linnaeus, 1758)
- Oxymeris subulata (Lamarck, 1822)
- Oxymeris arenaria (Linnaeus, 1758)
- Oxymeris maculata (Swainson, 1821)
- Oxymeris cerithiformis (Dillwyn, 1817)
