New in Guinness World Records 2021 The catapult flypaper trap Drosera glanduligera has now been included in the Guinness World Records 2021 as the fastest terrestrial predatory plant. It is actually faster than the VFT. Together with Dr. Simon Poppinga and the team of the Plant Biomechanics Group of the University of Freiburg, Irmgard and I are very happy about this great success of our common research work on the "Diva" (catapult-flypaper trap published 2012 in Plos One). Simon and the participating authors are additionally pleased, because based on the results of their experiments, the genus Utricularia (using U. australis as an example) was recorded too as the fastest aquatic predatory plant. We would like to take this opportunity to thank particulary Richard Davion (Adelaide, AUS) who was the first who reported about it, and all those who have supported us over the years in the research of snap-tentacles! If you want to see the experimental plants examined at the University of Freiburg in action, I recommend our topic "Carnivorous Plant Speed Contest":
Bladderworts (Utricularia) possess the fastest capture mechanism of all carnivorous plants. Ultrafast bladder traps suck in prey within less than a millisecond. That is 100 times faster than Venus’s flytrap snap shuts. Seven of the ten species that occur in Europe can be found in the region between Lake Constance, Swabian Alb and the Alps. Thanks to the support of the worldwide recognized CP-expert Dr. Jan Schlauer, we were able to film all seven Utricularia at their natural habitat. The terrific speed of prey captures show recordings with a high-speed camera, taken at the labs of the Plant Biomechanics Group of the Botanical Garden of the Albert-Ludwigs-Universität Freiburg (Germany). Dr. Simon Poppinga kindly provided these remarkable shots. In addition, a scanning electron microscope image featuring the quadrifid glands inside a bladder trap (both published in Poppinga et al. (2016). AoB PLANTS 8: plv140). As the film shows, their shape can be helpful for the determination of several quite similar looking species. Detailed information on our domestic bladderworts is provided by the scientific article “Die Gattung Utricularia in Bayern” (2014) published by the Bavarian Botanical Society, from which we quoted repeatedly in this film. To protect the partly endangered plants, but also because the access to some of the swamp areas without an experienced guide is not at all harmless, we do explicitly not mention exact locations. Our film provides English subtitles. Enjoy!
