This document summarizes and compares six types of carnivorous plants: bladderworts, sundews, butterworts, Venus flytraps, cobra lilies, and pitcher plants. It describes for each plant its name, characteristics of its leaves, the type of food it eats, and how it catches prey. The plants are all adapted to trap small insects through specialized leaves that attract, trap, and help digest prey to supplement their nutrition in low-nutrient environments like bogs or marshes.
