Invertebrate

Real World Example

Imagine trying to organize a stack of papers without a binder or a paperclip to hold them together. This situation is similar to how invertebrates function without a backbone, relying on other structures for support. Just as the papers might slide around or be less stable without that central organizing element, invertebrates like jellyfish and worms lack a spine and instead rely on other features like their exoskeleton or hydrostatic pressure to maintain their structure and function.
