What are some jawless animals?

Jawless animals, also known as Agnatha, are a group of fish that lack jaws and have a cartilaginous skeleton. Here are some examples:

Class Myxini (Hagfishes)

* Atlantic Hagfish: Found in the North Atlantic Ocean.

* Pacific Hagfish: Found in the North Pacific Ocean.

* Eelpout Hagfish: Found in the Northwest Atlantic Ocean.

* Slime Hagfish: Found in the Pacific Ocean.

Class Petromyzontida (Lampreys)

* Sea Lamprey: Found in the Atlantic Ocean, Great Lakes, and other freshwater systems.

* American Brook Lamprey: Found in rivers and streams of North America.

* European River Lamprey: Found in rivers and streams of Europe.

* Southern River Lamprey: Found in rivers and streams of southeastern United States.

* Pacific Lamprey: Found in rivers and streams of the Pacific Northwest.

It's important to note that while these animals are often referred to as "fish," they are actually a separate, ancient lineage of vertebrates. They are more closely related to land vertebrates than they are to bony fish.
