Parasitic Isopod

Caption

This parasitic isopod, which is related to rolley pollies, is one of the larger parasites encountered by the researchers in the estuaries. The isopod is almost one centimeter long, and was found infecting a crab, which it had "parasitically castrated," completely blocking the host's reproduction.
