  • We all know that we have to eat different kinds of food to get the nutrition that we

  • need.

  • So eating plants is a great idea if you want to be healthy. That’s why I like to eat

  • things like carrots, and spinach and tomatoes.

  • I like to eat plants, but what if plants... tried to eat animals?

  • Well, there are actually a few kinds of plants that are carnivorous, meaning they eat meat.

  • Now when I say meat, I’m not talking about chicken nuggets or hamburgers.

  • I’m talking about really small animals, like insects, spiders, and frogs.

  • Creatures like these have to be extra careful around meat-eating plants!

  • Probably the most famous carnivorous plant is known as the Venus Flytrap.

  • Venus Flytraps have leaves at the tops of their stems that kind of look like tiny, toothy

  • mouths.

  • Theyre not really mouths, but they serve the same purpose: to eat flies, and other

  • insects.

  • Usually, the trap’s leaves are wide open. And the inside of the trap smells like food

  • to insects. So they fly or crawl right into it, looking for a meal.

  • But if they aren’t careful, they become the meal instead.

  • On each half of the trap, there are three tiny hairs. If an insect touches two of those

  • hairs, the trap shuts, and the slender spines around the edges of the leaves close together

  • tightly, trapping the insect inside.

  • Then the trap slowly digests its meal, meaning it breaks its food down into smaller pieces.

  • It’s too bad for that little insect, but it will provide energy for that plant to live.

  • And Venus Flytraps aren’t the only kind of carnivorous plant.

  • Some plants, called sundews, attract bugs with colorful red and green leaves that are

  • covered with a sweet, stickydewthat sparkles in the sunlight.

  • The thing is, this dew acts like a kind of glue.

  • Any bug that lands on its leaves looking for a meal will get stuck. And soon the plant

  • just starts digesting it, soaking up nutrients from the bug’s body right through the leaves.

  • Now, some other carnivorous plants can consume even bigger prey.

  • Pitcher plants, for example, have big, brightly colored leaves, curled up into the shape of

  • a tube.

  • At the bottom of the tube sits a little pool of sweet liquid called nectar. Once again,

  • lots of different creatures are drawn to its tasty smell.

  • They creep, crawl, jump, or fly to the edge of the tube to see what’s in there to eat.

  • But the top is really slippery, and there are stiff hairs all along the inside of the

  • tube pointing down -- so once a creature starts to fall in, they can’t get out.

  • This clever kind of trap has allowed pitcher plants to catch not just bugs, but also make

  • meals of small frogs and even mice!

  • And finally, there are some meat-eating plants that don’t even live on land.

  • Bladderworts, for example, live and catch their prey in water.

  • These plants have tiny containers on their stems called bladders that float underwater.

  • Each bladder has an opening with a tiny flap on it, that can open and close, like a hidden

  • trapdoor.

  • When insects, like water fleas, trigger tiny hairs near the trapdoor, the door swings open,

  • and sucks the little creature in.

  • So now you know -- certain plants sometimes eat animals.

  • Like I said, it’s nice to have variety in your diet!

  • Thanks for watching SciShow Kids. Till next time!
