A 4-m stingray can eat 50 crabs a day.
0:08
They hoover up any who've lost their
0:10
shell.
0:16
Our spy becomes the crab's defender.
0:30
The ray will look for an easier meal.
0:34
Those with hard shells aren't worth the
0:35
trouble.
0:38
Males even stand and fight.
0:44
Those with soft shells hide among the
0:46
hordes.
0:52
Despite their brave defenders, the ray
0:55
can hunt them down.
1:02
It makes short work of extracting meat
1:05
from shell.
1:09
The crab in hiding makes her getaway.
1:14
She needs to get lost in the crowd.
1:17
The ray's victim is now an empty husk.
1:23
But he's yet to have his 50 a day.
1:27
And the fleeing crab is still in the
1:29
open.
1:40
She's made it.
1:44
Now to vanish among the masses.
1:51
The greater the numbers, the harder it
1:53
is for the ray.
2:03
Those with hard shells form an armored
2:05
fortress with a soft shell hidden
2:07
beneath.
2:17
Left in the open, spider crab is now a
2:19
sitting target.
2:24
It gets the full death ray treatment.
2:33
A crab's eye view of an untimely end.
2:43
But it's still live and kicking.
2:49
It's not over yet.
2:58
This time, the ray did it a favor.
3:05
Back firmly on its own eight feet, our
3:07
spy heads to the fortress.
3:13
It has a tower of crustaceans to climb.
3:20
But there's no need.
3:22
The crabs come to our spy.
3:34
They create a shield of legs and armor.
3:38
A living citadel built on sand.
3:43
Moving on.
3:45
Destroy.
