In this paper. we investigate the dynamics of a discrete-time predator-prey system involving group defense. The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically. It is shown that the system undergoes a flip bifurcation and a Neimark-Sacker bifurcation in the interior of R+2 by using bifurcation theory. https://www.spidertattooz.com/Antiqued-Brass-Color-Glue-On-Bar-Pin-Back-1-1-4-Inch-32mm-10-Pieces/
