Aquatic forms are abundant among water plants near the shore. However, giant isopods are encountering human threats. Most of these shores support a limited range of species, ranging from barren, highly mobile sands to more stable clean sands supporting communities of isopods, amphipods and a limited range of polychaetes. The combination of character states possessed by this new taxon may have a significant impact on interpretations of the phyletic relationships of isopods, recently evaluated using cladistic techniques by Brusca & Wilson (1991).
