Patelloida striata, commonly known as the striated limpet, is a species of marine gastropod mollusk belonging to the family Lottiidae. This limpet is a prominent feature of various marine ecosystems, particularly in intertidal zones.
Description & Characteristics
Patelloida striata is characterized by its conical shell, typically measuring up to 30mm in length. The shell’s surface is adorned with prominent radial striations, hence the species’ common name. Its color can vary from shades of gray to brown, often blending seamlessly with the surrounding rocks. The limpet’s foot is large and muscular, enabling it to cling firmly to its rocky substrate.
Habitat and Occurrence
Patelloida striata is widely distributed in the intertidal zones of the Indo-Pacific region. It is commonly found in rocky shores, where it adheres to the surfaces of exposed rocks. This species is particularly prevalent in the subtidal zone, which is submerged during high tide but exposed at low tide. The limpet’s ability to withstand exposure to air and varying salinity levels contributes to its success in intertidal habitats.
Taxonomy
Patelloida striata belongs to the class Gastropoda, a diverse group of mollusks characterized by their spiral shells. Within this class, it is classified under the family Lottiidae, which comprises various limpet species.
Feeding
Patelloida striata is a herbivorous grazer, primarily feeding on algae that grow on the rocky surfaces it inhabits. Using its radula, a ribbon-like structure with rows of teeth, the limpet scrapes off the algae, playing a significant role in maintaining the balance of the intertidal ecosystem.
