The arder of import.ance by the most frequent associates werc cruJlaceans. polychaetes, echinodenns and mollu.scs; by their abundance thc most important groups were polychaetes., crustaccans and cdlinodenns. The polychne1C Haplosyllis spongicola and the ophiurid Ophiaclb sQvignyi WC'I"C !he spec:ies with highest importance mnges. ¡reinla slrobilina and /. felix showed thc highest richness and species divcnity bccausc they had big iMer cbannels. Similarily lUlloog ayptic species of sponges was low, due to high species richness and lo sclectivily of the associales by lheir host lñe species richness and abundances were higher wilh increasing sponge volume. and both dccrcasc:d wilh depth.
