Spider Performs Amazing Engineering Feat
Have you ever stood at a construction site watching cranes lift heavy objects suspended by steel cables? Well, a spider in Madagascar can do the same thing. They routinely lift snail shells 20 times their weight using stronger-than-steel cables made of spider silk. This would be like a 180-pound piano mover lifting a piano weighing 3,600 pounds!
Olios coenobitus is an elusive spider that lives in snail shells which it hoists high up in bushes to protect itself from predators. Though the snail shell spider was first discovered in 1926, it wasn't until 2011 that a BBC camera crew was able to film it as it raised a snail shell off the jungle floor using a network of silk threads.
The spider begins by attaching a silk thread to the branch of a bush and then sticking the other end on the shell. He then attaches another silken strand but makes it a bit shorter than the first. Each time he makes the thread shorter and shorter. After doing this multiple times, the shell lifts off the ground and then heads upwards, where it will eventually become a roomy shelter for the spider.
With a brain no bigger than a grain of rice, this spider is able to pull off one of the most amazing engineering feats ever! How did that spider survive before it started hoisting shells many times its weight? And who taught it such complex engineering skills? The answer is obvious. But evolutionists stubbornly refuse to admit it.
