No, it is not because it does not really use the top jaw to move and chew with.
No. Only the bottom jaw can move, the top jaw is technically "part" of the head, so it is unable to move.
No they are not.
Clown fish do have jaws, so they are not a jawless fish.
Yes mammals has jaws ,a dog has jaws lions has jaws and they are both mammals.
:OO
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.
Yes, there are several animals that can move their upper jaws. Sharks are all able to move both upper and lower jaws independently but their skeleton is made of cartilage instead of bone. Snakes, crocodiles, some birds, and fish that eat food whole are among the animals with independent upper jaws.
No both jaws on the fish are not equally movable, only the lower jaw (mandible) is movable to chew food
No- only the lower jaw.
Jaws is a fish (a shark).....didn't you see the movie?
No. Both mammals and birds "inherited jaws" from a common reptilian ancestor which ultimately originated in an early fish.
Upper jaw is stable and is not movable. Together with lower jaw, it forms a DYNAMIC masticating system. Together both jaws also help in phonation.
Assuming you mean the Agnatha group of fish... They don't have movable jaws, like other animals and fish. They rely on a row of sharp teeth to slice into the flesh of their 'host' - then simply swallow the shredded flesh.
Jaws evolved from the gill bars on fish.
Clown fish do have jaws, so they are not a jawless fish.
Yes mammals has jaws ,a dog has jaws lions has jaws and they are both mammals.
smaller fish, with smaller jaws.
They eat smaller fish.
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
