This planctonic marine rotfer was 275 µm long. When I observe this species (without a coverslip) swimming, I see its marvellous movement in vertical and horizontal direction. Therefore I often think that somebody should construct an airplain or an helicopter following in an analogical way the construction and the swimming of this animal. Movement in water or in air probably have the same fundamental priciples.
