Popular on the bladderworts (Utricularia), these small traps are one of the most amazing wonders in the botanical world. These small traps (the largest is half an inch long) will suck in nearby prey and trap it in mere microseconds (faster than one can even blink). Most eat mosquito larvae, but the largest traps are known to eat tadpoles (eating the tail and sucking in more and more until the prey is consumed).

However, most hobbyists grow these plants for their flowers which can rival orchids.
