Carnivorous plants are those that feed on insects. The various species of these plants use different methods to capture prey. Sometimes the traps are fixed, and at other times moving. Some have leaves shaped vessels that accumulate in the water to drown the animals. Other secrete viscous substances in which victims are trapped. A third group has sensitive leaves that close on the insects, leaving them trapped. These plants have unique digestive juices that dissolve the prey. They grow in swamps, bogs and poor soil nitrogenous substances.
The naturalist Charles Darwin, formulator of the theory of evolution, was who named these plants under the name carnivores.
