The Marine Protected Area of the N.M.P.Z. hosts more than 30 protected or endangered species of invertebrates, fish and mammals, which are particularly important from an ecological and economic perspective, such as the noble pen shell, the purple sea urchin, the dusky grouper, the parrotfish and the common dolphin. Pollution, habitat degradation and overfishing are among the most significant, human induced, threats to the marine fauna. The N.M.P.Z. implements appropriate management measures in order to confront such threats and further protect biodiversity and the marine ecosystem.
