Invertebrate

Real World Example

Imagine trying to keep a stack of pancakes upright without a plate or any kind of support. Just like those pancakes would collapse and spread out without something solid to hold them together, invertebrates lack a backbone to provide structure and support. The connection here is that, much like the pancakes needing a plate to maintain their shape, animals with backbones (vertebrates) use their spine for structural integrity, whereas invertebrates have to rely on other body structures to maintain their form.
