The two types of jawless fish

                                                                               Hagfish                                                  

Sup guys.  Today I'm talking about the two types of jawless fish.  One of them is the hagfish.  The hagfish are very unique because they are invertebrates and have no jaws.

Another thing that's different about them is that unlike other fish they have bad eye sight and no scales.  Instead,they use tentacles that are on their faces to feel and sense everything that's around them.

They also like their food dead and eat left over dead skin and other stuff that's left over.They also have defense reflexes that make  and put slime all over their bodies so when predators like sharks attack them,they make tons of slime.  They can make slime for days.  They get the slime off of them by wrapping themselves into a knot and scraping it off.

These fish also have no bones.  Instead, they have dense fiber called cartilage. Their spine is made out of this, like our ears and noses are also made out of it.  They also live in the ocean.

They're not going to starve to death so these are some of the things they eat invertebrate fish,carrion and injured fish.They also eat it inside out.

                                                                                   

                                                                  Lamprey

The second jawless fish is the lamprey so yeah lampreys aren't that different from hagfish but,this is what makes them so different the lampreys teeth,mouths and sucking ability.

They eat by putting their mouths on a fish and sucking the meat and blood out of them.  There are lots of them too.

They are much more dangerous then hagfish with their teeth and sucking abilities.  Unlike other fish they are also parasites.

See you later.
