The prey can often run much faster than a Spider. Yet the feet will quickly become entangled in the sticky mess of the web. This is a great advantage for the Spider and then they will bite which injects the venom into the prey. This will immobilize them and then will meet their ultimate fate. Spiders won’t stick to their own webs though due to the oil on their limbs. They will build webs in different directions too. read more
