The genus Anilocra encompasses a group of parasitic marine crustaceans commonly referred to as fish lice. These small, flattened arthropods are classified under the family Cymothoidae and are known for their peculiar lifestyle. Fish lice from the genus Anilocra are primarily found in tropical and subtropical waters, particularly in coral reef ecosystems. They attach themselves to the bodies of their fish hosts using specialized appendages and feed on their blood and mucus. With their segmented bodies and distinctive mouthparts, Anilocra species have evolved adaptations that allow them to survive and thrive in their unique ecological niche. While their presence can be detrimental to fish health, they serve as an interesting component of marine biodiversity and the delicate balance of coral reef ecosystems.
