Meet the neighbors II - Crabbie Twins

Shrek likes food fresh and raw, period. He'll go after anything that moves.

However, the last thing he would like to gobble up would be these two new comers – ladies and gentlemen, the Crabbie twins.

However, even if Shrek is starving, I doubt that he has the gut to go after them. Trying to eat this eight-pointy-legs-and-a-pair-of-heavy-duty-claws creature, Shrek would spit it out in no time. If he did, I would do a C-section to get them out of his belly. Ahhh... maybe not.

Have you ever wonder why crabs don't walk front and back but walk sideways? They are just like a lot of insects with legs on both sides of their bodies, right? Never thought of that before? I don't blame you.

If you put your hand on the table, how will your fingers move? Mostly just bend and bounce them up and down, especially while you are thinking this silly crappy question, right?

Ding ding ding, now you got it! It's their joints that limit the movement of their legs. Since the rotation of each joint max out no more than 180 degrees along the vertical plan but not the horizontal's, they can only move their bodies to the left or right, but not the front and back.

Also, the bending of their legs helps squeezing themselves into holes or crevices that are smaller than their body width to escape predators.

It's fun to watch them walking in the water, isn't it?

Nevertheless, crabs are really tasty, yum yum!
