Creepy Wager
One day, John and Sue were out hiking. They saw a few tarantulas on the way. This gave John an idea to win some money. "Sue," he said, "I'll bet you five dollars that the tarantula over there can crawl without using its own leg muscles." Sue thought that she would win, but she didn't.

Answer
Tarantulas do not use muscles to move their legs. They control the amount of blood pumped into them to extend and retract their legs.Hide Answer Show Answer

well that was a creepy little trivia fact
Bet you found it on the Web
not really. i got it from a little nature book.
Cool, but even I knew the answer and i'm only 11.
well, ain't that a kick in the nuts(this statement is not meant to offend nebody, so please, dont take it offensively. thnk u)
I don't know y the difficulty rate is too high cuz i found it very easy Maybe because i love science
doesn't something have to have an internal skeleton in order to have muscles?
I'll give myself half credit for knowing that spiders don't have muscles but not the way they really move their legs. Full credit to you for a good teaser!
That is a little strange
I'm not sure about tarantulas but most spiders only EXTEND their legs by pumping blood(that's is why dead spiders often have their legs curled in. They pulled them in and could'nt get them out)
cool. didnt no that!
i didnt know that... creepy indeed
More trivia than a quiz. I suspected that they might not use muscles to move their legs, but you either know the answer or you don't. Nice test of knowledge though.
ew i hate spiders!!!!
