@@RralRonaldo Do some research you ppl make me laugh and then almost cry. A crab of that size would have a shell so thick that the spiders teeth would brake way before penetrating the crabs shell it could take gun fire and be fine. I don't know if you have eaten crab but their legs are all muscle that is why ppl eat crab legs. That crabs claws grip strength would be enough to crush a truck. Not to mention muscle is dense and very heavy. so since you are obviously a dim wit this all means the spider wouldn't stand the smallest chance. Please go back to school no matter how old you are we have enough dumb people in the world.
