Are there any relationship between the crabs size and their walking way?

no idea! i guess their limbs are like that naturally.
wat do u mean a relationship between crab size and walking way? like if they have larger size they walk more sidewards?

I think it has got something to with the way their eyes are located....don't know for sure

if it is walk straight they will not run for a long time. the simple, the feet will not have a good balance.
it do not walk straightly because it can not do that.
