Cymbula
Cymbula is a genus of limpets, a type of marine gastropod mollusc belonging to the family Patellidae. They are characterized by their conical, flattened shells and their ability to cling tightly to rocks and other hard surfaces in the intertidal zone. The genus is found in the northeastern Atlantic Ocean, including the coasts of Europe and North Africa, and the northwestern Atlantic Ocean, including the coasts of North America.
Common Names
Species within the genus Cymbula are commonly known as "true limpets".
Characteristics
Cymbula limpets are distinguished by the following characteristics:
- Conical, flattened shells with a wide, rounded apex
- A single, large muscle that allows the limpet to cling tightly to its substrate
- A radula, a ribbon-like structure with rows of teeth, used for scraping algae and other food from rocks
- A simple nervous system and a pair of eyes
Environment
Cymbula limpets are found in the intertidal zone, where they live on rocky shores and other hard surfaces. They are adapted to withstand the rigors of exposure to air and water during the tides. They typically live in areas with strong wave action and high levels of oxygen.
