Etymology
From Ancient Greek ἀ- (a-, “without”) + γνάθος (gnáthos, “jaw”).
Proper noun
Agnatha
- The jawless fishes, or agnathans; they have backbones and skulls like the scaly fishes, and like reptiles, mammals and other vertebrates on land, but they do not have paired jaws like humans or sharks; instead their mouthparts are round; they suck onto their prey or food and rasp away bits that they then swallow.
- A taxonomic superclass within the subphylum Vertebrata.
- 1889, Edward Drinker Cope, "Synopsis of the Families of Vertebrata", The American Naturalist, volume 23, page 852:
- The known members of the class Agnatha are a very small representation of those that once existed; and they present a great variety of character, having little affinity with each other.
- 2007, Chad Thomas et al., Freshwater Fishes of Texas, Texas A&M University Press, page 6:
- Current classification schemes have living fishes assigned to two superclasses (Agnatha, or jawless chordates, and Gnathostomata, or jawed chordates)[…].
