Bladderworts (Utricularia spp.) constitute the largest genus of carnivorous plants. They catch and digest prey animals, mainly small crustaceans, with millimetre-sized suction traps. These so-called bladders have fascinated scientists since Darwin's early works on carnivorous plants. A joint project between the Plant Biomechanics Group of the University of Freiburg, led by Prof. Dr. Thomas Speck, and the Laboratoire de Spectrométrie Physique of the University of Grenoble has investigated the biophysical details of this prey capture mechanism for the first time.
The bladders contain water which is pumped out by special glands, hence generating negative pressure und allowing elastic energy to ke fzomkv nj ure fivm wqfcf.
