FIRST RECORDS OF EPIBIONT CILIATES (CILIOPHORA) IN METHANE ENRICHED SEDIMENTS WITH SPECIES REDESCRIPTIONS

Еkaterina Ivanova, Igor Dovgal, Alice Newton

Abstract


The article is dedicated to re-discovery of ciliates Loricophrya bosporica (Suctorea) and  Cothurnia sp. (Peritrichia) found at nematodes from methane seep of the Ria Formosa lagoon (Southern Portugal). Based on authors’ data the lagoon sediments might be attributing to the hypoxic (periodically anoxic) methane seepage environment. The morphological characterizations of found ciliates with emphasis on poorly studied stylotheca structure in suctorian ciliate and macronucleus morphology in peritrich are presented.
