Are Lampreys and hagfishes are examples of what kind fishes members the class Agnatha?

You are absolutely correct! Lampreys and hagfishes are both members of the class Agnatha.

Agnatha is a class of jawless fishes, meaning they lack jaws and have a more primitive skeletal structure than other fish groups.

Here's a breakdown:

* Lampreys are parasitic, meaning they attach to other fish and suck their blood.

* Hagfishes are scavengers, feeding on dead or dying fish and other marine animals.

Both groups have elongated, eel-like bodies and lack paired fins. They are considered the most primitive of living vertebrates.
