They are muscles – don’t let that slip away from your understanding. Octopus arms (and elephant trunks and your tongue, for that matter) are muscular hydrostats – they can bend, stretch and change shape, without skeletal support. And that means looking at our octopi pals. To find a natural analogue for those abilities, you need to look at tossing out the skeleton altogether.
Along with squeezing through small openings, they can elongate their bodies, and take on different shapes. A small mouse’s skull can have the diameter or a penny.īut our heroes most definitely aren’t rodents. The rule of thumb, according to exterminators, if the skull can fit, the mouse can fit. And lastly, they’ve got slightly stretch connective tissue and very strong back legs to push them through the small openings from which they emerge to freak you out. Secondly, mice (and other animals that can do the squeezing act) don’t have collar bones holding their front “arms” away from their neck. How do they squeeze through then? For one, their fur makes them look larger than they are, so the volume you’re looking at squeezing through a hole is different than what you’re initially thinking.

Feel free to freak out and start checking your room for small holes now.īut mice don’t have collapsible skeletons. Let’s take a mouse for example – a common exterminator saying is that if there’s a hole the width of a #2 pencil, a mouse can fit through it. Small rodents and cats for example, have no problems making it through impossibly tight spots. Think of an animal – you’re probably thinking of one with a bony endoskeleton, right? There are some weirdos (sharks, rays and other classes of fish with cartilaginous skeletons, for example), but nearly every vertebrate on earth has a bony endoskeleton.īut in our world we do have animals – animals with skeletons – that can squeeze through very small spaces. That’s just weird in and of itself…skeletons are one of the big classification categories that separate a lot of animals from everything else. Fantastic might not have normal, human skeletons anymore. Okay – already out of the gate, we’ve got a weird thought to consider: Elastigirl, Plastic Man, Elongated Man and Mr. Seriously – like a real one, a skeleton on the inside, made of calcium and magnesium compounds?
