Cymodoce truncata is a species of marine isopod crustacean, commonly known as the “truncata isopod.” It is a member of the family Sphaeromatidae, which are known for their characteristically rounded bodies and the presence of a distinct “brood pouch” in females.
Description & Characteristics
Cymodoce truncata is a relatively small isopod, typically reaching a maximum length of approximately 10 millimeters. Its body is flattened dorsoventrally, meaning it is wider than it is tall. It has a distinctive, elongated head with two pairs of antennae. The body segments are covered in a hard, chitinous exoskeleton.
Habitat and Occurrence
Cymodoce truncata is a common inhabitant of coastal marine environments, specifically in the intertidal zone. It is often found in rocky and sandy habitats, particularly in areas with seagrass beds and algae. Cymodoce truncata exhibits a preference for shallow waters, typically occurring in depths ranging from the high intertidal zone down to approximately 5 meters. The species is considered to be a key component of the marine benthos, the collection of organisms that live on the seabed.
Taxonomy
Cymodoce truncata belongs to the Class: Malacostraca, Order: Isopoda, and Family: Sphaeromatidae. This classification places it within a large group of crustaceans characterized by their segmented bodies and specialized appendages.
Feeding
Cymodoce truncata is primarily a detritivore, meaning it feeds on decaying organic matter, including algae, dead animals, and plant debris. This feeding behavior plays an important role in recycling nutrients within the marine ecosystem.
