all fish have fisn unless their fins wear down which is usally caused by sickness disease and or the levels in your tank if this happens i recommend keeping an eye on it . it could cause death and spread to your other fish. if you but a small little glass tank and put some medicine in their it will be fine
Agnatha is the group you are thinking of; commonly referred to as hagfish or lamprey.
no they have to have fins to swim.
Jawless fish and cartilaginous fish have cartilaginous skeletons, and bony fish have skeletons made from bone. Cartilaginous fish and bony fish both have jaws, paired appendages, and whole vertebrae, and jawless fish lack jaws, paired appendages, and often are without whole vertebrae. Cartilaginous fish can have scales or be naked, jawless fish are naked, and bony fish have scales. Bony fish have swim bladders, and cartilaginous fish do not. Jawless fish, cartilaginous fish, and bony fish all have fins, gills, and dorsal nerve cords that lead to a distinct brain. They all also have postanal tails and notochords.
I believe the correct answer is Gnathostomat fish, with paired upper and lower jaw structures; and Agnath fish, which generally have only a toothy suction cup like upper jaw mouth structure.Taken from:http://en.wikipedia.org/wiki/Jaw
That is the scientific designation for " jaw-less fish. "

No, it is not because it does not really use the top jaw to move and chew with.

hi
The answer is Jaw
Well, the sharks fins are not sharp. they are made of cartilage which the shark is mostly made of. Cartilage is what is in your nose and your ears. That is why they bend so easily. Not many fish have cartilage inside them. The fish that do are called, you guessed it, cartilaginous fish. There is also bony fish and jaw-less fish.
