Elthusa [Elthusa]

Description

Elthusa is a genus of isopods that parasitize mainly marine fishes, attaching to the external parts of the fish such as the gills. Their life cycle and interaction with the host can vary significantly among species. They are distinguished by their relatively small size and the complex structure of their limbs and mouthparts, adapted for a parasitic lifestyle.
