Patelloida
Patelloida is a genus of limpets, a type of marine gastropod mollusk belonging to the family Patellidae. Limpets are characterized by their conical shell, which is adapted to cling tightly to rocky surfaces. Patelloida species are commonly found in the intertidal zone of the Indo-Pacific region. They are herbivorous and graze on algae, playing a crucial role in the ecological balance of their habitats.
Common Names
Common names for Patelloida species include:
- Blackfoot limpet
- Striped limpet
- Common limpet
Characteristics
Patelloida species share several distinctive characteristics. They have a robust, conical shell that is typically 2-5 cm in diameter. The shell is often covered in a layer of periostracum, a thin, organic coating that protects the shell from erosion. Their foot, which is used for locomotion and adherence to surfaces, is large and muscular.
Patelloida species exhibit a variety of shell colors and patterns, which can be helpful for identifying different species. Some common patterns include stripes, spots, and bands. The shell is also often marked with growth lines, which indicate the stages of the limpet's development.
Environment
Patelloida limpets are found in the intertidal zone of rocky shores, where they are exposed to a wide range of environmental conditions. They are tolerant of both submersion and emersion and can withstand significant fluctuations in temperature, salinity, and wave action.
These limpets often form dense aggregations on rocky surfaces, where they compete for food and space. They play an important role in the ecosystem by grazing on algae and controlling the abundance of primary producers.
