Seven scuticociliates (Protozoa, Ciliophora) from Alabama, USA, with descriptions of two parasitic species isolated from a freshwater mussel Potamilus purpuratus Author Xuming Pan text European Journal of Taxonomy 2016 249 1 19 journal article 37563 10.5852/ejt.2016.249 09521c67-41e4-40da-9d43-97412eb789e9 118-9773 200009 urn:lsid:zoobank.org:pub:43278833-B695-4375-B1BD-E98C28A9E50E Mesanophrys cf. carcini Small & Lynn in Aescht, 2001 The newly observed specimens resemble those of free-living forms of Mesanophrys carcini Small & Lynn in Aescht, 2001 in all respects except: numbers of somatic kineties (10 in parasitic forms vs 11 in free-living forms) and body shapes (variable in parasitic forms vs constant slim and spindle-shaped to long fusiform in free-living forms) ( Grolière & Leglise 1977 ; Song & Wilbert 2000 ). These differences may be due to different life-styles and abundance of food sources.
