Anomia peruviana is a species of marine bivalve mollusk belonging to the family Anomiidae. These bivalves are commonly known as “jingle shells” due to their unique ability to produce a clicking sound when disturbed.
Description & Characteristics
Anomia peruviana is a small to medium-sized bivalve, with shells typically reaching a maximum length of 5-7 centimeters. The shell is irregularly shaped and often has a somewhat flattened, oval appearance. The exterior surface of the shell is usually rough and covered in small, irregular ridges. The color of the shell varies depending on the individual specimen and its environment, ranging from white to brown or even reddish-brown. One of the most distinctive features of Anomia peruviana is its ability to attach itself to a variety of surfaces using a strong, calcified byssus. This byssus acts like a biological cement, enabling the bivalve to firmly secure itself to rocks, coral reefs, and other marine substrates.
Habitat and Occurrence
Anomia peruviana is a common inhabitant of shallow coastal waters in the eastern Pacific Ocean. It is typically found in the intertidal and subtidal zones, and it can also be found attached to submerged structures, such as pilings and docks. The species is particularly abundant in the waters off the coast of Peru and Chile, hence its species name. Anomia peruviana prefers habitats with moderate wave action and abundant food sources. It is a key component of the marine ecosystem, contributing to the biodiversity of the intertidal and subtidal zones.
Taxonomy
The species Anomia peruviana belongs to the class Bivalvia, order Pectinida, and family Anomiidae. This family is characterized by its members having a shell with one valve (the right valve) that is attached to a substrate by a byssus, and the other valve (the left valve) is often free-moving.
Feeding
Like other bivalves, Anomia peruviana is a filter feeder. It obtains its food by drawing in water through its inhalant siphon and filtering out microscopic organisms, such as phytoplankton and zooplankton. The food particles are then trapped in mucus and transported to the mouth for digestion.
