Siggi_Hartmeyer Posted March 15 Report Share Posted March 15 Rapid Prey Slinging Sundews It always looks sensational when the rapid catapults of some sundews fling their prey into the sticky tentacles of the trapping leaf in a matter of seconds or even milliseconds. The largest of the catapult-flypaper traps known to date, Drosera glanduligera, is even faster than the famous Venus flytrap. In the past, who would have thought a sundew could do that? The exciting research into these fast trapping movements in the genus Drosera only began in the 1980s with the still rather sedate Drosera burmannii / D. sessilifolia. We show with impressive recordings how research into the fast catapults progressed. Even today there are still surprises. In this film we show all known rapid catapult-flypaper traps and present video evidence of the tentacle movement of Drosera australis, a further rapid pygmy Drosera. 2 Quote Link to comment Share on other sites More sharing options...
