"Agnathans" Meaning
Agnathans are a group of ancient fish-like vertebrates that lived during the Paleozoic Era. They are characterized by the absence of jawbones, hence the name "agnathans", which comes from the Greek words "a" meaning without and "gnathos" meaning jaw. They were a transitionary group between the earlier jawless fish, such as hagfish and lampreys, and the later vertebrates with jaws. Agnathans were often carnivorous and fed on worms, crustaceans, and other small invertebrates. They played an important role in the evolution of vertebrates and are now extinct.
