Phys.org / Venus flytrap's snap may come from rapid cell wall softening, not water flow

The Venus flytrap (Dionaea muscipula) is a marvel of nature, a highly effective killer that doesn't have to move an inch to capture and kill its prey. It releases a fruity nectar scent to attract flies and other insects. ...
