Invertebrate

Real World Example

Imagine trying to stack a tower of Jenga blocks without a central supporting piece. Just like how the tower wobbles and lacks stability, an invertebrate is an animal that lacks a backbone, which provides structure and support in vertebrates. In the same way the Jenga tower relies on its pieces to maintain balance without a central spine, invertebrates rely on other structures, such as exoskeletons or hydrostatic pressure, to maintain their form and function.
