These animals are called invertebrates. Invertebrates have no backbone. Examples of invertebrates are insects.
Animals without backbones, called invertebrates, developed near the end of the Precambrian. Imprints of jellyfish and marine worms have been found in late Precambrian rocks. Because invertebrates were soft, they weren't easily preserved as fossils. This is one of the reasons why the Precambrian fossil record is so sparse.

Invertebrates
animals without backbones are invertebrates. octopi and squids have no shells, but are invertebrates because they contain no backbone. if they had a backbone, they'd be vertebrates.
