A plant trap that sucks water inSourced
Aquatic bladderwort uses a tiny triggered door
Active traps of aquatic Utricularia hold lower pressure than the surrounding water. Contact with trigger hairs opens a door, drawing prey and water inside before it closes. This differs from the conspicuous closing leaves associated with other carnivorous plants.
Opening a door is the start of this capture.
