One of the most remarkable plants in the world, which captures its prey
by means of a trap formed from part of its leaf. It has been induced to
snap at and hold a bristle. If an insect lighting on the leaf touches
one of six very sensitive hairs, which pull the trigger of the movement,
the two halves of the leaf close rapidly and the fringing teeth on the
margin interlock, preventing the insect's escape. Then follows an
exudation of digestive juice.]
