According to Utz (2007), living hosts often represent a suitable attachment site for peritrichs and other sessile organisms, because the water currents passing by the host can supply the epibionts with food particles and can facilitate the removal of waste material.
This peritrich-dytiscid interaction may be at least moderately detrimental to the dytiscid larvae, although the peritrichs may derive some advantages (5) from the association.
Assessment of the number of colonies and zooids of Zoothamnium per substrate area showed that this genus was the dominant peritrich from April 15th to April 21st, but was outnumbered by Vorticella spp.
The present study investigated the attachment to nonliving substrates of the peritrich epibiont Zoothamnium intermedium.
Peritrich ciliates commonly colonize planktonic crustacea (Hermann and Mihursky, 1964; Green, 1974; Henebry and Ridgeway, 1979; Lopez et al., 1998), with the majority of the reports on this epibiotic relationship focusing on the effects of these epibionts on host survivorship and reproduction (Kankaala and Eloranta, 1987; Xu and Burns, 1991; Xu, 1992; Weissman et al., 1993).
In the present study, growth, colonization, and proliferation rates of the peritrich epibiont Zoothamnium intermedium were evaluated in the laboratory, feeding on bacteria alone and on a mixture of bacteria and Isochrysis galbana Stein, 1878.
