<P> Porcupines are rodents with a coat of sharp spines , or quills , that protect against predators . The term covers two families of animals , the Old World porcupines of family Hystricidae , and the New World porcupines of family Erethizontidae . Both families belong to the infraorder Hystricognathi within the profoundly diverse order Rodentia and display superficially similar coats of quills : despite this , the two groups are distinct from each other and are not closely related to each other within the Hystricognathi . </P>
