Mammoth Memory


Invertebrates are animals without backbones (in a sense, they are the opposite of vertebrates, which have backbones).

Mnemonic of an invertebrate that does not contain a backbone

To remember the term invertebrate, imagine an earthworm goes to a building site for a job, but is told that because it doesn’t have a backbone, it will have to insert a brace (invertebrate) to make it stronger.

Note: An amazing fact is that 97% of animals are classified as invertebrates.
