Crab's legs aren't very flexible in the front - back direction, so sideways motion is easier and faster. Remember that they have an external skeleton! Also, crabs are much better swimmers and spend much more time in the water than on land.

yes,the joint on the legs on one side pull the crab and those on the other side push.producing a sideways movement.and thier legs are not flexible as most of the animals thats why they cant move like others which makes them funny.

I think their eye can't see straight that prevented them from going forward, but only side way.

I haven't given it a thought too why they move sideways. Maybe one reason is their legs is not flexible enough like other creatures who can do forward or back or just a thought, maybe they'll lose their balance if they did so.
