Abstract: Predator–prey interactions are influenced by various ecological factors, including cooperative hunting, prey refuges, and harvesting, which can shape population dynamics, ecosystem stability, and species survival. This study proposes and studies a prey–predator system that interacts in two zones: the protected and the unprotected. It is assumed that the predator has the capability of cooperative hunting behavior. The objective of this study is to understand the role of a predator’s capabilities in the dynamical behavior of the system. All the solution properties are studied. The stability analyses of the equilibria are investigated. The impact of perturbing the parameters is assessed using local bifurcation analysis. Persistence conditions of the system are established. Numerical simulations using the fourth-order Runge-Kutta method in MATLAB confirm all analytical results. It was shown that the system has at most two boundary equilibrium points, and the positive equilibrium point, if it exists, is multiple. In addition, a numerical study shows that the system with only point attractors exhibits a wide range of bistability behaviors.
