Descripción
Class of vertebrates representing numerous primitive, fish-like, jawless animals, such as lampreys, hagfishes, and some extinct groups. Some classifications list Agnatha as a superclass with lampreys and hagfishes as classes. Jawless fishes probably arose from ancient small, softbodied filter-feeding organisms.
