The Venus flytrap closes around an insect in just 0.3s or faster, while the waterwheel use thin translucent traps to snare copepods and other aquatic invertebrates.

Charles Darwin was so enamoured by this striking adaptation, and the speed with which it works, that he described the Venus flytrap as being “one of the most wonderful plants in the world.”

“Darwin was fascinated by carnivorous plants in general and the Venus flytrap in particular, I think, partly because they go against type,” says Don Waller, a botanist at the University of Wisconsin, in Madison, US.

“In his time and ours, most of us feel that plants are passive, harmless, and can’t move. But the Venus flytrap acts like an animal, it moves fast and eats fresh meat.
