Ionella [Ionella]

Description

Ionella is a genus of parasitic isopods with a preference for infesting the gills of crabs. These parasites have a significant impact on the host's health, including impeding normal gill function, which can lead to reduced oxygen intake and overall vitality. Ionella species are recognized by their compact and flattened body shape, designed to fit snugly within the confined spaces of their host's gill chambers.
