The Parasitic Isopod – Anilocra physodes is a fascinating marine crustacean that exhibits a parasitic lifestyle. Belonging to the family Cymothoidae, this isopod is a prominent example of the intricate relationships that exist within the marine ecosystem.
Description & Characteristics
Anilocra physodes, like other members of its family, possesses a flattened, elongated body, adapted for its parasitic existence. The isopod’s body is segmented, with a distinct head, thorax, and abdomen. It can reach a maximum size of approximately 20 millimeters. The body coloration of Anilocra physodes is typically a mottled brown, providing camouflage amongst the marine environment.
Habitat and Occurrence
Anilocra physodes is a common inhabitant of the tropical and subtropical regions of the Atlantic Ocean. This parasitic isopod finds its home in both the neritic and oceanic zones, often attaching itself to various marine fish hosts. The depth range of Anilocra physodes extends from the surface waters to depths of approximately 100 meters.
Taxonomy
Anilocra physodes is classified within the Class Malacostraca, Order Isopoda, and Family Cymothoidae. The Malacostraca class encompasses a diverse range of crustaceans, including crabs, lobsters, and shrimp. Isopods, characterized by their flattened bodies, belong to the Order Isopoda, and the Family Cymothoidae comprises a diverse group of parasitic isopods.
Feeding
As the name suggests, Anilocra physodes is a parasitic organism. It feeds on the blood and bodily fluids of its marine fish hosts. The isopod uses its mouthparts to pierce the host’s flesh and extract nourishment. This parasitic behavior can be detrimental to the host fish, potentially leading to weakness and even death.
