My Secret Life as Plankton] -
0:29 - 0:31How did I get here?
-
0:33 - 0:36Well, it's a stranger story
than you might think. -
0:37 - 0:40I came from a world of drifters,
-
0:40 - 0:43a place few humans have ever seen.
-
0:44 - 0:46The world of plankton.
-
0:47 - 0:52I came from a batch of a million eggs,
and only a few of us survived. -
0:55 - 0:59When I became a larva,
I moved among other drifters. -
0:59 - 1:04["Plankton" comes from the Greek
"planktos" for wandering] -
1:08 - 1:13My fellow plankton came in all sizes,
from tiny algae and bacteria -
1:13 - 1:16to animals longer than a blue whale.
-
1:21 - 1:25I shared my nursery
with other embryos and juveniles, -
1:25 - 1:29from clams and crabs
to sea urchins and anemones. -
1:32 - 1:34(High pitch sound)
-
1:34 - 1:37We drifting animals
are called zooplankton. -
1:39 - 1:43The most common animals here
are copepods and krill. -
1:43 - 1:44(Buzzing)
-
1:46 - 1:48You could search the world over,
-
1:48 - 1:52but you'd never find a place
more diverse than my childhood home. -
1:54 - 1:56A teaspoon of seawater
-
1:56 - 1:59can contain more
than a million living creatures. -
2:02 - 2:05It can be a pretty tough
existence, though. -
2:05 - 2:09Trillions are born here,
but only a few make it to adulthood. -
2:14 - 2:17He may be no larger than a pin head,
-
2:17 - 2:21but this crab larva
is an arrow worm's worst nightmare. -
2:22 - 2:25(Bumping noises)
-
2:32 - 2:34(Buzzing)
-
2:36 - 2:40Epic battles between carnivores
like these are just one way to get food. -
2:42 - 2:46But the real powers
of this place come from phytoplankton. -
2:47 - 2:49Single-celled life
-
2:49 - 2:51that transforms sunlight
and carbon dioxide -
2:51 - 2:53into edible gold.
-
3:00 - 3:05Phytoplankton are the base
for the largest food web in the world. -
3:07 - 3:09During the night,
-
3:09 - 3:11many animals like me
would rise up from the depths -
3:11 - 3:14to feed on this sun-powered feast.
-
3:15 - 3:17(Maraca sound)
-
3:19 - 3:23I was part of the largest daily
migration of life on Earth. -
3:25 - 3:27During the day,
-
3:27 - 3:31I'd return to the darkness,
where I'd join my bizarre companions. -
3:33 - 3:34(High pitch buzz)
-
3:34 - 3:35(Flapping noises)
-
3:35 - 3:39Cannibals, like this
sea butterfly mollusk, -
3:39 - 3:40that eats its next of kin.
-
3:45 - 3:47And comb jellies,
-
3:47 - 3:50that beat cilia like rainbowed eyelashes.
-
3:56 - 3:59Some of these snare
their prey with sticky tentacles, -
4:00 - 4:03while others just take
a bite out of their cousins. -
4:05 - 4:07And siphonophores
-
4:07 - 4:09that catch prey with toxic fishing lures.
-
4:15 - 4:19But my favorite would have
to be the crustacean Phronima. -
4:20 - 4:24Its monstrous looks inspired
the movie "Aliens." -
4:25 - 4:28It can catch tiny bits in its bristles,
-
4:28 - 4:31but prefers larger prey like salps.
-
4:35 - 4:39With two sets of eyes,
this female prowls the deeper water. -
4:41 - 4:43Prey in hand,
-
4:43 - 4:46she performs one
of the strangest behaviors -
4:46 - 4:48in the entire animal kingdom.
-
4:51 - 4:53With body parts from her victims,
-
4:53 - 4:57she delicately assembles
a barrel-like home -
4:57 - 5:01feeding her young until they can drift off
and survive on their own. -
5:05 - 5:10Best of all, they make the perfect
snack for a small fish like me. -
5:13 - 5:15Here among the plankton,
-
5:15 - 5:18the food web is so tangled and complex,
-
5:18 - 5:21even scientists don't know who eats whom.
-
5:24 - 5:25But I do.
-
5:29 - 5:32At least now you know a bit of my story.
-
5:33 - 5:36There's so much more to me
than just a tasty meal.
