We study the hadronic molecular structure of hidden heavy pentaquarks - new\nexotic states composed of charmed/bottom baryons and $D(D^*)/B(B^*)$ mesons.\nBased on the observation of three pentaquark candidates $P_c^+(4312)$,\n$P_c^+(4440)$, and $P_c^+(4457)$ by the LHCb Collaboration we consider the\nclassification of possible flavor partners composed of charmed baryons and\n$D(D^*)$ mesons within the hadronic molecular approach. We extend this\nclassification to the bottom sector. Using phenomenological Lagrangians we\nconstruct baryon-meson bound states governed by the Weinberg-Salam\ncompositeness condition. As an application we consider strong two-body decays\nof the new exotic states into a light baryon and $V=J/\\psi,\\Upsilon$ or\n$P=\\eta_c,\\eta_b$ mesons. Results are presented in the heavy quark limit.\n
