sentences:  "Bodo" is roughly bean-shaped and is often missed in samples from water or terrestrial environments due to its small size.The genus was originally described in 1831 by Christian Gottfried Ehrenberg as having an ovoid body, a very short tail, transparent and able to show the colour of the food that it ingests.Ehrenberg also described the type species, "Bodo saltans", as being green, but this was later refuted as it was discovered that the green colouration came from the photosynthetic bacteria that it ingests.
