1251 horned isopod
Scientific Name Deto echinata
Comments As the name suggests, the horned isopod is easily recognized by the pairs of "horns" arising on the back of each thoracic segment. It is often confused with the similar looking Ligia, to which it is only distantly related. It is an air breathing isopod found associated with kelp and other drift algae washed up on rocky shores of western South Africa. It feeds mainly on this algae as well as live prey and carrion.

3583 Button isopod
Scientific Name Sphaeromene polytylotos
Comments The button isopod is found amongst mussels and barnacles on rocky shores and reefs along the coast of western South Africa. It is herbivorous, feeding on filamentous algae and on simple green algae.

5225 Tongue-eating isopod
Scientific Name Cymothoa exigua
Comments The tongue-eating isopod causes degeneration of the tongue of its host fish, the rose snapper, Lutjanus guttatus, and it then attaches to the remaining tongue stub and floor of the fish's mouth by hook-like pereopods. In this position the isopod superficially resembles its host's missing tongue. Brusca & Gilligan (1983) hypothesize that these isopods serve as a mechanical replacement for the fish's tongue and represent the first known case in animals of functional replacement of a host structure by a parasite. This relationship is so-far known only from the Gulf of California.

Title A Guide to the Coastal Isopods of California
Description The California marine isopod fauna numbers 190 named species (eight of which are questionable species, nomen dubia or species inquirenda), representing thirty-six families in eight suborders. Although we have enumerated all species known from California waters, the keys treat only species occurring in the intertidal and supralittoral zones, plus the commonly encountered fish parasites of the family Cymothoidae. However, the coverage of the key includes the entire coastline of California and Oregon. At least fourteen species are thought to have been introduced to California’s coastal zone: one cirolanid, four sphaeromatids, one asellotan, one epicaridean and seven oniscids.
