Gangesia [Gangesia]

Description

Gangesia is a key genus in the family Gangesiidae, with species that are parasitic on freshwater and brackish water fishes, particularly in Asian regions. While primarily found in freshwater environments, certain species have been identified in estuarine habitats, indicating a degree of salinity tolerance. The genus is characterized by its scolex, which is equipped with bothridia for attachment, and a segmented body that facilitates nutrient absorption. Gangesia species are significant in studies of fish parasites and aquatic ecosystem health, given their specificity to host species and potential as bioindicators.
