UTILIZATION AS SHELTER.In view of the fact that the numerous specimens of Echinothambema found in rhizomes used these as a shelter and apparently not for food. it seems likely that this is also the case with the remaining isopod species; investigations of storiach contents of these species cannot be made due to the scarcity and small size of the animals. Fifty-one of the 55 species of isopods in Thalassia rhizomes are from 4"Kurchatov" Stations the same stations only another 21 isopods were found outside rhizomes(Wolff, 1975)
