First record of epibionts peritrichids and suctorians (Protozoa, Ciliophora) on Pomacea lineata (Spix, 1827)

Abstract

This study made a survey on the ciliate protozoans from Peritrichid and Suctorian taxa, epibionts of Pomacea lineata (Spix, 1827) (Ampullariidae

Report of rotifer-ciliate-gastropod hyperepibiosis found on snail (Mollusca) from Goa, India

“…For example, the species was found on shell of Physa acuta Draparnaud, 1805 in a eutrophic stream of Brazil (Sartini et al 2018), on Lymnaea atenuata Say, 1829 and Physa osculan Haldeman, 1841 in a lake from Mexico (Lopes-Ochoterena, 1964). Dias et al (2006) reported Epistylis sp. on Pomacea lineate (Spix, 1827).…”

“…The ciliates of genus Epistylis are often found attached on different substrates such as macrophytes, stones, and as unspecific epibionts of freshwater invertebrates, bugs, beetles, decapods, copepod crustaceans and gastropod molluscs (Jankowski, 2007). Epistylis were earlier reported as epibiont on gastropod shell (Sartini et al, 2018;Lopes-Ochoterena, 1964;Dias, D`Ávila, Agosto, 2006;Dias, Wieloch, D'Agosto, 2008;Utz, 2007).…”

Microscopic marine invertebrates are reservoirs for cryptic and diverse protists and fungi

“…The majority of ciliate ASVs in our dataset clearly belong to clades of known ecto-and endosymbionts, with a marked overrepresentation (compared to their relatively lower known diversity) of taxa from Suctoria and especially Apostomatia (epibiotic and parasitic subgroups of the Phyllopharyngea and Oligohymenophorea, respectively). Although most of these taxa are already known symbionts of marine invertebrates, they are generally documented in much larger specimens: adult echinoderms [51,52], large cephalopods [53] and other molluscs [54], hydroids [55], and crustaceans [56]. Notably, associations between the suctorian genus, Ephelota, and small crustaceans (copepods) have also been reported [57,58].…”

Morphological description of the gastropod Heleobia australis (Hydrobiidae) from egg to hatching

“…The associations may not be obligatory, and the epizoic communities are generally characterized by a high number of species which may inhabit highly specialized niches (FENCHEL, 1987). Some eggs of H. australis presented epibiont ciliates of Peritrichia subclass, ciliates in this subclass provided many examples of an epizoic way of life, living on other molluscs (DIAS et al, 2006).…”
