Animals that do not have backbones are called invertebrates. Some examples of invertebrates include arthropods (such as Spiders, crabs, insects, etc), worms, jellyfish, molluscs (such as snails and octopi), sponges, and more. Interesting to note is that there are far more insects than there are animals with backbones, whether you count by number of species, amount of biomass, or number of individuals.

The invertebrates do not have backbones. They are mainly primitive animals. They usually have a less complex body design than those animals which have backbones.
