are drosophila vertebrates
Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Some of the so-called invertebrates, such as the Chaetognatha, Hemichordata, Tunicata and Cephalochordata are more closely related to the vertebrates than to other invertebrates.This makes the term invertebrate almost meaningless for taxonomic purposes.ertebra means a joint in general, and sometimes specifically a joint from the spinal column of a vertebrate. In turn the jointed aspect of vertebra derived from the concept of turning, expressed in the root verto or vorto, to turn.
