These cells exhibit an elongated, spindle-shaped structure with a lengthy flagellum, measuring between 53 to 119 micrometers in length and 13 to 28 micrometers in width. They have a distinct long and slender front section resembling a neck, which gradually tapers towards a pointed posterior end. Additionally, their central region appears to be swollen and somewhat resembling a top. These cells primarily reproduce through asexual means, specifically through binary fission.
