Venus flytrap

There's something unsettling about the idea of meat-eating plants, as this trapped Pacific tree frog can attest. Venus flytraps are one of the few plants that can move rapidly enough to capture bugs (and sometimes small mammals) for digestion.

Found on every continent except Antarctica, sundews ensnare creepy-crawlies on their sticky pink stalks and then absorb the bugs' nutrients.

Venus flytraps thrive in poor soil because they can gather extra nutrients from meaty insects and arachnids. Tiny hairs on their clamshell-like traps cause the traps to snap shut when triggered. Enzymes then digest the plant's prey, a process that take days.

In addition to their bright pink tentacles, sundews produce small white flowers.

Like Venus flytraps, sundews can move their tentacle-like appendages in response to stimulation by prey. But sundews move relatively slowly compared with Venus flytraps, so they depend on a sticky mucus to trap bugs.

Murderous maze

The cobra lily's snake-like beauty hides a pit of horrors. Lured into the pitcher by sweet-smelling nectar, bugs find themselves lost in a maze of false exits. Few make it out alive. Instead, it's down the slippery tube to a small pool of bacteria-rich water, where the bugs become plant food.

The hooded pitcher plant, or Sarrancenia minor, grows in coastal regions from Florida to North Carolina. White patches let light into the hood, perhaps to lure insects further inside.

Another Borneo pitcher plant, Nepenthes rafflesiana elongata, has evolved as an ideal roost for small woolly bats. The relationship is mutually beneficial: Bats get a place to sleep during the day, and the pitcher plant gets the guano.

Tree Shrew Lavatory

Some carnivorous plants have a rather creative way of getting their nutrient fix. The Nepenthes lowii pitcher plant in Borneo attracts tree shrews with sweet nectar. If they need to relieve themselves while eating, the shrews are perfectly positioned on the pitcher plant. Gross? Not for the plants, which get between 57 percent and 100 percent of their nitrogen from shrew poop.
