The Striped Fish Louse, scientifically known as Anilocra capensis, is a parasitic isopod crustacean belonging to the family Cymothoidae. This species is commonly found in marine environments, particularly in the coastal waters of South Africa.
Description & Characteristics
The Striped Fish Louse, Anilocra capensis, is a relatively large isopod, typically reaching a maximum size of 30 millimeters. It possesses a distinctive flattened, elongated body with prominent stripes running along its length. These stripes, which give the louse its common name, are a combination of dark brown and lighter hues, providing excellent camouflage against the host fish’s scales. This species exhibits sexual dimorphism, with females being larger than males.
Habitat and Occurrence
The Striped Fish Louse, Anilocra capensis, is a common inhabitant of the coastal waters of South Africa. It thrives in the temperate waters of the Agulhas Bioregion, which is characterized by its strong currents and diverse marine life. This species is typically found in the intertidal zone and shallow subtidal regions, preferring rocky shores and kelp forests. The depth range of the Anilocra capensis is relatively shallow, rarely exceeding 10 meters, as this species prefers areas with abundant host fish populations. The Anilocra capensis can be classified as a species that occurs in the neritic zone, which refers to the coastal waters of the ocean extending from the shoreline to the edge of the continental shelf.
Taxonomy
The Striped Fish Louse, Anilocra capensis, is classified within the Class Malacostraca, Order Isopoda, and Family Cymothoidae. The Malacostraca, which include various crustaceans like crabs, shrimp, and lobsters, are known for their highly diverse body plans. The Isopoda, characterized by their flattened bodies and seven pairs of walking legs, includes diverse species like pill bugs and woodlice. The Cymothoidae, also known as fish lice, are a family of parasitic isopods that attach themselves to fish, drawing blood and nutrients from their hosts.
Feeding
The Striped Fish Louse, Anilocra capensis, is a parasitic isopod, meaning it derives sustenance by feeding on the blood and tissues of its host fish. It attaches itself to the host using its strong claws and then feeds on the fish’s blood, causing discomfort and potentially weakening the host. The louse’s feeding habits can cause lesions and infections on the host fish, making them vulnerable to other predators or diseases.
