Description :

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.
