Catching prey: It is similar to Venus Flytrap, but underwater, abilities to catching preys depend on water temperature. One impuls is enough to close trap, except older leaves which need more implulses. Stimulating trigger hair causes the traps to close, it takes 0,01-0,02 seconds, if there is no prey the trap reopens in several hours. It produces digestant enzyme and 'bubble' into tighly closed trap.
