Sort of like you see in cartoons, a terrestrial animal that could be “squished” without breaking any bones and goes back to their non-squished state. It’s something I think is more observable in aquatic life, like say octopuses that can squeeze themselves into small spaces.
While there may be examples of what you are thinking of, I think the most common solution developed by evolution is invertebrates without an exoskeleton, meaning no skeletal structure at all.
Would you please elaborate on your question? What do you mean by an elastic skeletal system?
Can you give an example, even if fictional?
