“…Among the freshwater crustaceans inhabited by rotifers are Branchiopoda, Copepoda, Isopoda, Amphipoda, and Decapoda. The freshwater louse Asellus aquaticus serves as substrate for at least 10 rotifer species, of which the bdelloids Embata commensalis, E. laticeps, E. parasitica, Philodina convergens, Rotaria magnacalcarata, R. murrayi, and R. socialis, and the monogononts Encentrum hofsteni, E. kulmatyckii, Testudinella caeca, and T. elliptica are among the most typical (e.g., Budde 1924, Wiszniewski 1953, May 1989, Cook et al 1998, Fontaneto & Ambrosini 2010. Brachionus rubens, B. sessilis, and to a lesser extent B. variabilis and Epiphanes daphnicola are commonly reported as epibionts of several species of the different orders of Cladocera; the latter species is also the only epibiotic rotifer recorded from copepods (Cyclops).…”
