In contrast, bopyroids and niscoidea (commonly referred to as epicarideans) are cryptoniscoids (795 species) are unique in that they use crustaceans unique in using crustaceans as both intermediate and as both intermediate and definitive hosts (Figure 1A–H). The definitive hosts. In total, 795 epicarideans are known, isopods that parasitize crustacean hosts comprise approximately representing ,7.7% of described isopods. The rate of 7.7% of all isopods (estimated at 10,300 species; [3]) and are the description of parasitic species has not matched that of focus of this review. free-living isopods and this disparity will likely continue due to the more cryptic nature of these parasites. Paleontological evidence shows bopyroids and cryptoniscoids Distribution patterns of epicarideans are influenced by a (commonly referred to as epic
