Chapter 33 Invertebrates
... Invertebrates—animals without a backbone—account for 95% of known animal species and all but one of the roughly 35 animal phyla that have been described. More than a million extant species of animals are known, and at least as many more will probably be identified by future biologists. Inverte ...
