We can cite the case of the 'ajo' (Caryocar costarricense), the 'ojoche' (Brosimun costaricanum) and the caracolito cedar (Ruptiliocarpon caracolito).Corcovadoºs diverse fauna is remarkable; many of the species of this region are in danger of extinction, despite the large numbers still found in the region. The red macaw or 'Guacamaya' (Ara macao), the wild boar (Tayassu pecari), the jaguar (Felis onca) and the crocodile (Crocodylus acutus) confirm this fact. Just as in the case of the caracolito tree, in the future, studies could reveal the existence of other unknown species, which if it were not for the conservation of the park, would be lost forever without ever having been described..
