Los rotíferos fueron observados,descritos y dibujados por el grandísimo microscopista holandés Leeuwenhoek, hace ya más de tres siglos. Los llamó animálculos que ruedan . Estas ilustraciones son un pequeño homenaje a él pues tener la fortuna de poder usar un foldscope puede hacernos revivir lo que debió sentir aquel pañero en una Europa que desconocía el mundo de los microorganismos y que, sin estudios superiores y con un ingenio superlativo, retó a los científicos de la Real Sociedad de Londres.
Rotifera were observed, described and drawn by the greatest dutch microscopist Leeuwenhoek, about three centuries ago. He named them wheeled animalcules . These videos are a tribute to him due to the incredible experience that the use of foldscope has meant to me: the wonder of discovering the tiniest, just as this textile merchant must have felt in an European continent unaware of the microcosmos. He himself, with no University attendance and an awesome ingeniosity, challenged the scientific members at the London Royal Society.
En este vídeo se puede observar cómo son capaces de crear torbellinos de agua gracias a la corona de cilios. Asimismo, se percibe el movimiento del mástax, órgano faríngeo para la digestión mecánica.
In this video, water whirls created by their crowns of cilia can be observed. The movement of the jaws located in the pharynx are visible too.

La lucha constante por atraer pequeños microorganismos actuando como verdaderas aspiradoras acuáticas.
The continuous struggle to attract smaller microorganisms acting as aquatic “vacuum-cleaners”.

No siempre viven fijos a un sustrato, sino que pueden desplazarse nadando mediante el movimiento de sus cilios.
They do not always live attatched to soil or debris, and can swim around by moving their cilia.
