Natica
Natica is a genus of predatory sea snails, marine gastropod mollusks in the family Naticidae, the moon snails. These snails are found in a variety of marine habitats, including sandy bottoms, rocky shores, and coral reefs. Natica species are known for their distinctive, smooth, often glossy shells, which can range in color from white to brown to gray.
Common Names
Common names for Natica snails include moon snails, sand collars, and button snails. These names often refer to specific species within the genus.
Characteristics
Natica snails are characterized by their:
- Conical, smooth, and often glossy shells. The shell aperture is usually wide and rounded, and the outer lip is often thickened.
- Predatory nature. They feed on other marine invertebrates, primarily bivalves, which they paralyze using a venomous proboscis.
- Ability to burrow. Many species of Natica are able to burrow into sand or mud, using their muscular foot.
- Characteristic "collar". Many species produce a thick, calcareous collar around the opening of their shell, which is believed to protect them from predators.
Environment
Natica snails are found in a wide variety of marine environments, including:
- Sandy bottoms. This is the most common habitat for Natica species, as they are able to burrow into the sand and ambush their prey.
- Rocky shores. Some species of Natica are found on rocky shores, where they may live in crevices or under rocks.
- Coral reefs. Natica snails are also found in coral reef habitats, where they may prey on bivalves living among the coral.
