When I was a young man sowing (or possibly sewing) my wild oats, I had cause to attend a certain clinic. "What's the difference between crabs & lobsters?" I asked of the nurse. "Crabs walk sideways." She replied.
I frantically ran out of the clinic pulling my hair out crying "Oh my God! I've caught the Lobsters!"
Sorry, couldn't resist that little frivolity.

It's to do with the crab's hard exoskeleton combined with its laterally elongated shell which gives it a limited range of movement generally and its ten legs little lateral movement specifically.
It's the only way it can go but this has conferred some advantages on crabs because they can get into very tight crevices to escape predators.
