Notoacmea daedala is a species of small, marine limpet found in the intertidal zone along the coasts of the Pacific Ocean. This species is characterized by its distinctive shell shape and color pattern. Notoacmea daedala is an integral part of the intertidal ecosystem, playing a significant role in the food chain and contributing to the overall biodiversity of the region.
Description & Characteristics
Notoacmea daedala is a small limpet, typically reaching a maximum size of around 20 millimeters in length. Its shell is conical in shape, with a low, rounded apex. The shell exhibits a distinctive color pattern, often displaying shades of brown, gray, or reddish-brown with irregular patches or streaks of white or yellow. The interior of the shell is typically white or light gray with a pearly luster.
Habitat and Occurrence
Notoacmea daedala is primarily found in the intertidal zone, inhabiting rocky shores and exposed headlands. This species prefers areas with moderate wave action and good water circulation. Notoacmea daedala can be found in the upper intertidal zone, where it is exposed to air for extended periods during low tide, but it can also be found in the lower intertidal zone, where it is submerged for longer durations. The distribution of Notoacmea daedala ranges from the Pacific coast of North America, including California, Oregon, and Washington, to the Aleutian Islands of Alaska. This species is also found in the coastal waters of the Pacific Northwest, making it a prevalent presence in these aquatic ecosystems.
Taxonomy
Notoacmea daedala belongs to the Class Gastropoda, which includes snails and slugs, and the Family Lottiidae, commonly known as the true limpets. This family encompasses numerous species of limpets, characterized by their conical shells and grazing habits.
Feeding
Notoacmea daedala is a herbivore, feeding primarily on algae that grows on rocks and other hard surfaces. The limpet uses its radula, a ribbon-like structure covered in teeth, to scrape off algae and other microscopic organisms. As a grazer, Notoacmea daedala plays a crucial role in controlling the growth of algae and maintaining the balance of the intertidal ecosystem.
