0:00:00.228,0:00:04.122
Animals dont eat it;[br]it eats animals.

0:00:04.122,0:00:05.697
And there's one right here.

0:00:08.795,0:00:09.611
Watch.

0:00:20.779,0:00:23.103
This is Venus's flytrap.

0:00:23.103,0:00:26.241
It shapes its traps[br]from the ends of its leaves.

0:00:26.241,0:00:29.009
One or two hairs on their[br]surface act as triggers.

0:00:31.005,0:00:32.674
Here comes a meal.

0:00:36.142,0:00:39.146
Touch the hair[br]and the trap is sprung.

0:00:42.397,0:00:44.375
There's now no escape.

0:00:46.352,0:00:52.049
The beetle's struggles stimulate the plant[br]to close the trap even more tightly.

0:00:52.049,0:00:56.548
It now produces digestive acids from[br]glands on the inner surface of the leaf,

0:00:56.548,0:01:00.032
which first kill and then[br]dissolve its victim's body.

0:01:01.082,0:01:05.679
Growing in the same Carolina swamp,[br]there's another carnivorous plant.

0:01:06.965,0:01:09.452
These are the trumpet pitchers.

0:01:09.452,0:01:11.535
They, like the Venus's flytrap,

0:01:11.535,0:01:15.475
find so little nutriment in this[br]impoverished water-logged soil

0:01:15.475,0:01:18.387
that they supplement it[br]with the bodies of animals.

0:01:20.920,0:01:23.770
Their traps are also[br]formed from leaves,

0:01:23.770,0:01:26.153
but leaves that have[br]been folded lengthways

0:01:26.153,0:01:29.734
to make a vertical tube[br]which fills with water.

0:01:30.463,0:01:33.192
(birds chirping,[br]insects buzzing]

0:01:40.286,0:01:42.792
These spectacular trumpets[br]may look like flowers,

0:01:42.792,0:01:44.122
but, of course,[br]they're not.

0:01:44.122,0:01:47.372
Though in a sense,[br]this bright yellow top to them

0:01:47.372,0:01:49.782
serves the same[br]purpose as a petal.

0:01:49.782,0:01:52.446
It's an advertisement[br]of a delicious reward.

0:01:52.446,0:01:56.160
And the reward itself[br]is under here.

0:01:58.931,0:02:00.508
Sweet nectar.

0:02:00.508,0:02:02.667
But if an insect[br]comes to collect it,

0:02:02.667,0:02:05.217
and strays into the[br]mouth of the trumpet,

0:02:05.217,0:02:07.046
then it's doomed.

0:02:09.290,0:02:14.064
(Dramatic music,[br]animal noises)

0:02:23.676,0:02:25.582
The inside of the throat[br]of the trumpet

0:02:25.582,0:02:29.680
is covered with microscopic[br]downward-pointing spines.

0:02:33.367,0:02:37.506
As long as it stays on the rim,[br]the ant is alright.

0:02:37.506,0:02:40.768
But if it strays off it...

0:02:40.768,0:02:44.437
it falls into a pond[br]of water and drowns.

0:02:44.437,0:02:46.410
The tiny corpse dissolves

0:02:46.410,0:02:49.490
and the marsh pitcher[br]absorbs the resulting soup.

0:02:54.918,0:02:58.641
And where one ant goes,[br]others are likely to follow.

0:02:59.871,0:03:02.813
(dramatic music continues)

0:03:15.230,0:03:18.292
The marsh pitcher[br]attracts other animals too.

0:03:18.292,0:03:22.450
This frog may be hoping to eat some[br]of the insects before the pitcher does,

0:03:22.450,0:03:26.371
but if it loses its footing,[br]the plant will eat <i>it.</i>
