In the animals appeared on Earth,
00:00:32
The blue whale is the largest.
00:00:34
Their volume is at least twice the largest dinosaur
00:00:40
Blue whale height and basketball courts quite
00:00:41
Weight equal to the sum of the 40 African elephant.
00:00:44
If these data are not enough to shock you,
00:00:46
Then please read on.
00:00:48
Blue whales can grow to such a large
00:00:50
Only eating small creatures called krill.
00:00:58
They are smaller than your little finger.
00:01:00
The krill micro body
00:01:02
Seems in many ways have contributed to the blue whale evolution.
00:01:08
, Although they are small,
00:01:10
But the groups of krill always a large number.
00:01:12
To improve efficiency,
00:01:13
Blue whales evolved
00:01:15
Known as the the onrush Predator "eating patterns.
00:01:17
In simple terms, the blue whale on the one hand will accelerate the swim to the shrimp,
00:01:20
On the other hand will most Zhang farther apart.
00:01:22
To improve the eating capacity, very large blue whale's mouth wide open.
00:01:26
Extends from the mouth to the abdomen under
00:01:28
Special fold-like blubber layer,
00:01:30
So the whales can devour a large number of
00:01:32
The seawater containing food.
00:01:44
Containing seawater and krill component
00:01:48
Is 1.25 times the weight of the whale.
00:01:50
After the whale to discharge water,
00:01:51
And delicious krill reserved.
00:01:54
This step is to use the baleen,
00:01:56
Whalebone comb shape
00:01:58
Texture and whale tongue
00:02:00
As well as the nails, the hair is the same.
00:02:08
Blue Whale heart as big as cars
00:02:12
Children can climb the artery,
00:02:15
The blue whale's tongue and elephants as heavy,
00:02:17
But it's esophagus is too narrow,
00:02:20
A piece of bread can choke on it.
00:02:23
Blue whale's body structure
00:02:24
Makes them only eat krill such a small food.
00:02:31
It is estimated that the blue whale eat 4 tons of krill a day.
00:02:35
Rely on this amazing body structure,
00:02:36
Blue whales each dive eating energy
00:02:38
It is this action 90 times consumed.
00:02:42
A big mouth krill can provide 480,000 calories
00:02:46
You eat 1900 hamburgers to get so much heat.
00:02:54
Why, then, the blue whale is so big?
