Characteristics
Muricidae are typically medium to large-sized snails with strong, conical shells. The shells are often ornamented with spines, nodules, or ribs, and the aperture (opening) is usually elongated and narrow. Many species have a siphonal canal, which is a long, narrow extension of the aperture. The operculum, which is a horny or calcareous plate that covers the aperture, is often absent or reduced in Muricidae.
Muricidae are carnivorous and typically feed on other mollusks, crustaceans, and worms. They use their radula, a ribbon-like structure with rows of teeth, to drill through the shells of their prey. Some species, such as the oyster drill (Urosalpinx cinerea), are considered pests because they can damage oyster beds.
Environments
Muricidae are found in a variety of marine environments, including:
- Rocky shores
- Coral reefs
- Seagrass beds
- Mudflats
- Deep-sea environments
They can be found in both shallow and deep water, from the intertidal zone to depths of over 1,000 meters.
