is an extinct genus of bony fish of Carboniferous and Permian which plays the same ecological role as the roaches and perch of modern times. In fact, the paramblypterus species is composed of several very diverse subspecies (some resemble roach, others perch) but all live in fresh and salt water. Paramblypterus feeds on small crustaceans, tadpoles and fish fry but it is also a prey for amphibians and big fish of the time.
