The Venus Fly Trap is the most famous of all carnivorous plants due to the active and efficient nature of its unique traps. It may be famous, but it's also threatened. The plant's two hinged leaves are covered in ultra-sensitive fine hairs that detect the presence of everything from ants to arachnids. Trigger the hairs and snap! The trap will shut in less than a second.
Most early scientists believed the plant to be a myth until physical proof of such a plant's existence was offered. The Venus Fly Trap has no cousins and is the only member of the Dionaea genus.
The VFT produces a short fleshy leaf that carries a modified tip that forms two sides of the trap, each side contains three hairs which when touched two to three times causes the two sides to spring shut in a very rapid motion fast enough to catch flies and other insects. The leaf once closed then exudes a series of enzymes that slowly dissolve the internal juices of the insect and hence supply the plant with food. After a few days, the trap re-opens leaving the skeleton of the insect to be washed out by the rain.
If no insect is caught by the trap, the leaves re-open within a few hours to prepare for the next insect to arrive. The VFT comes from soils that are very poor in nutrients so the plant has adapted itself to finding nutrients from other means rather than starve. VFTs can easily grow without ever eating insects.

Pitcher Plant
The Pitcher plant is a carnivorous plant, a meat-eater. Carnivorous plants usually live in nitrogen-poor soils. They have 'learned' to augment the inadequate nitrogen available in the soil by capturing and consuming insects!
The inside of the tubular-shaped leaf is lined with downward-pointing hairs. These hairs block an insect from climbing up the tube and escaping. The fluid in the bottom of the tube contains digestive juices that will consume the insect prey.
