Trachelomonas (track-ell-owe-moan-ass) is an autotrophic euglenid flagellate. The genus is distinguished from others because the cells live within a loose fitting lorica with a small opening. The lorica of many species is elaborated with spikes or spines. The lorica accumulates metal salts with age, becoming brown and brittle and often obscuring the bright green colour of the chloroplasts within the cell. Red eyespot evident near the anterior of the cell. There is one emergent flagellum which emerges from the opening of the lorica. After division of the daughter cells will emerge from the opening of the lorica. Most freshwater but occasionally found in brackish habitats. Phase contrast. This picture was taken by David Patterson, Linda Amaral Zettler and Virginia Edgcomb of material from the salt marsh at Little Sippewissett (Massachusetts, USA) in Autumn, 2000 and in Spring and summer, 2001.

Trachelomonas
From the collection
Little Sippewissett salt marsh, Massachusetts, USA
| Description of Trachelomonas: Euglenids, with plastids, free-swimming, with an envelope with sharply defined neck or collar surrounding an apical pore through which the flagellum emerges; naked cells escape from the envelope after reproduction (and at other times); shape and size of loricas used to define species; loricas upon secretion ed, are colourless and smooth at first but soon becomes brown, ornamented (pores, punctae, spines, warts or ridges) and brittle with ferric hydroxide and manganese salts; with pyrenoids; a few species are colourless and osmotrophic; eyespot and flagellar swelling present; euglenoid movement and cell rotation occur within the envelope; canal opening sub-apical even though the envelope pore is apical; very speciose, almost exclusively freshwater, common in acidic to neutral waters (pH 4.5-7), often in peaty pools and other habitats rich in reduced iron and manganese, cosmopolitan; type species: T. volvocina (Ehrenberg) Ehrenberg 1833. |
