Year 2 – March 31, 2013 – Venus Flytrap
The Venus flytrap is a carnivorous plant native to subtropical wetlands on the East Coast of the United States. It catches its prey—chiefly insects and arachnids— with a trapping structure formed by the terminal portion of each of the plant’s leaves and is triggered by tiny hairs on their inner surfaces. When an insect or spider crawling along the leaves contacts a hair, the trap closes if a different hair is contacted within twenty seconds of the first strike. The requirement of redundant triggering in this mechanism serves as a safeguard against a waste of energy in trapping objects with no nutritional value.
Thanks to Wikipedia (again), now I know about Venus Flytrap. I have always thought that this plant must be native of some exotic places in Asia, who would have thought that east coast USA is capable of producing such vicious carnivorous plant.
