Nature is constantly teaching humans the knowledge of survival, such as: run faster, see farther, improve your racial expertise, and you can survive the competition.
However, the survival rules of the crab spider are very different from the "spider professional", it does not rely on the net to prey, but has 100% accuracy!
Crab spiders survive by camouflage and attack. It hides in a place that is not easy to find by protective color, waiting for an opportunity to attack and capture prey - a spider has the heart of a lion!
However, camouflage and attack are only one of the things that the crab spider does not do, and it has an even more surprising skill!

Because the attack of the crab spider relies on the concealment given by the protective color, and once the white flowers are left, the environment of the attack becomes very embarrassing.
So the crab spider decisively chose to change color - how reluctant it is to tie the net!
The discoloration process takes several days and involves two important cell layers of crab spiders.
The surface cells of the crab spider appear white before discoloration, and when the crab spider sees other colors, such as yellow, it secretes xanthanin in the surface layer. At this time, the underlying cells will play a mirror-like function, reflecting the yellow out, making the crab spider appear yellow!
It's true: there's nothing difficult in the world, as long as you are willing to climb!
