Hyperotreti
Fishes of class AGNATHA (myxini) have tooth-like structures that are composed of KERATIN..
Myxini (hagfishes) are chordates and craniates. they have a cartillagenous skull but no vertebra or jaws.
Hagfish. Hagfish are primitive marine animals that belong to the class Myxini. They are known for their lack of jaws and paired fins.

Hyperotreti
marine craniates of the class Agnatha or Myxini, also known as Hyperotreti. Some researchers regard Myxini as not belonging to the subphylum Vertebrata. That is, they are the only living animals that have a skull but not a vertebral column

Myxini, Cephalaspidomorphi, Chondrichthyes, Osteichthyes, Amphibia, Reptila, Aves, Mammalia
Myxini (hagfishes) are chordates and craniates. they have a cartillagenous skull but no vertebra or jaws.
Myxini, the hagfishesLampreys are as well, but their class has not been determined.
There are actually eight: Myxini, Cephalaspidomorphi, Chondrichthyes, Osteichthyes, Amphibia, Reptila, Aves, Mammalia
Hagfish. Hagfish are primitive marine animals that belong to the class Myxini. They are known for their lack of jaws and paired fins.
Fish are general classified into one phylum which is known as chordata. There some fish like the hagfish that are not able to fit into this phyla properly.
There is no antonym for example, you can't have no example. Therefore there is no antonym for example.
Phylum Chordata simply consists of all animals that, at least in their embryonic phase, have a structure called the notochord. In the vertebrates, the notochord develops into the vertebrae, i.e. the backbone. Some primitive chordates, though, including the tunicates, lancelets, and hagfish, do not ever develop vertebrae, although they have/have had a notochord. Hence, Subphyla Urochordata and Cephalochordata, and Class Myxini are invertebrate chordates.
