<P> Segmentation in animals typically falls into three types , characteristic of different arthropods , vertebrates , and annelids . Arthropods such as the fruit fly form segments from a field of equivalent cells based on transcription factor gradients . Vertebrates like the zebrafish use oscillating gene expression to define segments known as somites . Annelids such as the leech use smaller blast cells budded off from large teloblast cells to define segments . </P>
