Perspectives and relationships, in the Silurian then decreasing in numbers, finally to disappear from the fossil record at the close of the Devonian. Since the first jawed vertebrates, the acanthodians were not to be found earlier than the upper Silurian, it is hardly surprising that the agnathans and gnathostomes should have bee

Respiration and feeding,t in myxinoids, although the single median, recurved palatine tooth may help the hagfish to maintain its purchase on its food during the tearing action of its jaws. The biting and rasping teeth of the lamprey are carried on tooth plates above and below the mouth, as well as on the apex of the piston

The heart and circulatory system,ta gives rise to a series of aortic arches supplying the gills, of which there are eight in the lamprey; the first — the hyoid — serving the anterior hemibranch of the most anterior gill pouch. The remaining afferent arteries divide to supply the anterior and posterior hemibranchs of adjacent gill p

The pituitary,d from the neural tissue of the floor of the diencephalon, and the adenohypophysis, an epithelial component originating from the epithelium of the embryonic mouth cavity. The cyclostomes diverge from the typical vertebrate pattern in that the adenohypophysial tissue develops from a naso-hypophysial
