Toads have a spinal cord and backbone, which means they are vertebrates.
Around 3% of animals are vertebrates (animals that have a backbone). This includes approximately 64,000 species. Examples of animals that have a backbone are; sharks, reptiles, mammals and birds.
All animals with a backbone are vertebrates. All birds have a backbone. All owls are birds.
There isn't really a common name, since vertebrates are all animals with a backbone/internal skeleton, as opposed to bugs, octopuses, and other animals that don't have that kind of skeletal system. A vertebrate has vertebrae (vertebrae is the plural of vertebra). A vertebra is one of many bones in the spine.
No they don't because all worms are invertebrates (animals without a backbone). (:
Animals with a backbone belong to the phylum Chordata. This phylum includes vertebrates such as fish, amphibians, reptiles, birds, and mammals, which all possess a notochord or backbone at some stage in their development.
Insects are the only creatures without backbones. The rest of the other animals in other animal classification all have a backbone.
No, they have a backbone. Vertebrates are ALL animals that have backbones. Invertebrates are ALL animals that do not have backbones.
No they don't. e.g. invertebrates
Other animals that do not have a backbone include arthropods (such as insects and spiders), mollusks (such as octopuses and snails), and cnidarians (such as jellyfish and coral). These animals have different types of support structures instead of a rigid backbone.
No, they do not have a backbone, they have an exoskeleton.
