Lottia versicolor, commonly known as the versicolor limpet, is a species of marine gastropod mollusk. It is a common inhabitant of intertidal zones, known for its characteristic shell and its ability to cling tightly to rocks.
Description & Characteristics
Lottia versicolor has a conical shell with a slightly pointed apex. The shell is typically 15-25 millimeters in diameter, with a maximum size of 35 millimeters. The shell color can vary considerably, ranging from light brown to dark brown, often with reddish-brown markings or stripes. The underside of the shell, known as the foot, is muscular and flat, allowing the limpet to adhere strongly to its substrate.
Habitat and Occurrence
Lottia versicolor is found in the intertidal zones of the northeastern Pacific Ocean. Its range extends from Alaska to Baja California, making it a prevalent presence in these aquatic ecosystems. This species prefers rocky shores and can be found in both the lower and mid-intertidal zones, where it is exposed to the elements during low tide.
Taxonomy
Lottia versicolor belongs to the Class Gastropoda, which includes a wide variety of snails and slugs. It is a member of the Family Lottiidae, commonly known as limpets. This family contains a diverse group of marine gastropods adapted to life in the intertidal zone.
Feeding
Lottia versicolor is a herbivore, feeding primarily on algae that grows on rocks. It uses its radula, a tongue-like structure with rows of teeth, to scrape off the algae. This feeding behavior plays a crucial role in maintaining the balance of the intertidal ecosystem. The limpets’ grazing activities help control the growth of algae and create space for other organisms.
