Waterwheel Plant (Aldrovanda Vesiculosa)
Closely related to the Venus flytrap, the aquatic, free-floating waterwheel plant has similar snap-traps on the end of each ‘spoke’ emerging from the main stem. Each trap is covered in ‘trigger hairs’ that cause the trap to close when stimulated.
Fun Fact
Winter-hardy Aldrovanda form turions as a frost survival strategy. At the onset of winter, the growth tip starts producing highly reduced non-carnivorous leaves on a severely shortened stem. This results in a tight bud of protective leaves which, being heavier and having released flotational gases, breaks off of the mother plant and sinks to the water bottom, where temperatures are stable and warmer.
