    Have no bones and their skeletons are made of cartilage. Hagfish are either predators or scavengers and some lamprys are too. There are species of lamprys which filter feed on detitrus, though.

    b-have cartilage skeleton

    They are the most primitive forms of fish and have cartilaginous skeletons.Fertilization is external which is a characteristic of primitive chordates and do not feed on other fish or invertebrates.They don’t have any jaws
