"Most animals, in terms either of numbers of individuals, or of number of species are invertebrates. Of the 34 phyla of animals in the Kingdom Animalia 32.5 of them are invertebrates in that they are lacking a spine or vertebra, that collection of bones that runs along the back of animals like Fish, Frogs, Snakes, Birds and Mammals."
