InvertebratesBiggestGroupInvertebrates are the biggest group of animals.
About 97% of the animals on Earth are invertebrates.


Invertebrates do not have a backbone (or a spine).
They don’t have a skeleton inside them.


We can classify invertebrates into different groups:

  • arthropods,
  • molluscs
  • and other groups of invertebrates.
