Carnivorous Plants

Carnivorous plants represent an unusual evolution in flora -- plants that attract and trap prey, have their own digestive process for the flesh of the prey, and absorb the resulting nutrients. Hundreds of species exist, derived from ten primary lineages of carnivorous plants. Several hundred other plants are classified as "protocarnivorous", meaning that they lack one or two of the three characteristics. Carnivorous plants fall generally into one of five categories: pitfall, flypaper, snap, bladder, and lobster-pot. Each type has a unique method of trapping prey.

• Pitfall traps consist of a rolled-leaf tube partially filled with liquids
• Flypaper traps consist of a sticky surface that the insect gets stuck to
• Snap traps are fast-moving leaves that close on an insect
• Bladder traps use a filled bladder and a vaccuum to 'inhale' insects near the opening
• Lobster-Pot traps have passages that allow insects to only move towards their stomach
