Actually most animals (over 90%) lack a backbone. The animal kingdom is seperated to many phyla. Almost all of them lack a backbone and so are called "invertibrate". The proifera phyla has sponges. The cnidaria phylum has coral, sea anemones and jellyfish. The molluska phylum has snails, clams and octopus. There are several phyla for worms, such as platyhelminthes (flat worms), annelida (segmented worms) and nematoda (round worms). Most animal species belong in the arthopoda phylum, which has centipeds, millipedes, aracnids and crustaciens. One of its classes, insects, make up over half the animal species. Then the echinodermata phylum has sea urchins, sea stars and sea cucumbers. Finally there is the single cordata phylum. Some of the members lack a true spine, like lancelets and sea squirts. Others are the vertibrites, which are all the animals that do have a backbone. They include humans, other mammels, reptiles, birds, amphibians and fish. Seperating the animal kingdom to invertibrates and vertibrites is no longer very relevent to zoology.

The virtual world of Tron is without an animal but in the 'real' world the original programmer's son Sam Flynn has a small dog .
the goddess Ashara is the oldest goddess to exist on Earth. She is the creator of the Vampires and all creatures in the world other than humans and animals. She is, without doubt, a nightmare
No, there are many more animals without backbones than there are those that have backbones.
Animals without backbone are invertebrates, because vertebra means backbone.
Invertebrate animals are amimals without a backbone.
ALL animals that have a backbone are "vertebrates". ALL animals without a backbone are "invertebrates". Man is an animal with a backbone.
Lewis Kenna
Single celled animals.
Insects are the only creatures without backbones. The rest of the other animals in other animal classification all have a backbone.
if youre into spiders, bugs or snails they have no backbone
Vertebrates and invertebrates... V = Animals with backbone IV= Animals without backbone
Lewis Kenna
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.
Animals without an vertebral column, which would be a backbone or spine, are called Invertebrates.The "in" prefix of the word meaning "without" Therefore 'in'--without, 'vertebrate' --bone/s in the column of the spine.
