Buddenbrockia plumatellae was described as a species in 1910 by O. Schröder, when he observed strange wormlike parasites in the body cavity of freshwater colonial invertebrates called bryozoans. These worms actively wriggle with sinusoidal movements inside their host and grow to 1–3 mm (0.04–0.12 in.) in length. Their body plan is extremely simple, lacking a gut, nervous system, or even external sensory structures. In fact, the worms appear to be morphologically identical from both ends. Their bryozoan hosts grow by budding new zooids, the individuals that collectively form the colony, and Buddenbrockia proliferates along with the growth of its host to form dense infections of worms (Fig. 1a).
