Examples of jawless fishes?
hagfish (myxinoidea) and lampreys (petromyzontoidea)
There are two main groups of jawless fishes – hagfishes and lampreys.
Hagfishes are often called slime eels due to their slimy, scaleless skin. They have a distinctive head with tentacles around the mouth that are used to locate food, such as dead or dying fish. Some common species of hagfish include the Pacific hagfish and the Atlantic hagfish.
Lampreys have a distinctive circular mouth with teeth used to attach to and feed on other fish. They have a bony plate instead of a jawbone. The sea lamprey is a well-known species that is often referenced in discussions about invasive species, as it has caused significant ecological damage in the Great Lakes region.
Other examples of jawless fishes include the slime hagfish, Pacific lamprey, and Arctic lamprey.
