Of the almost 100 species of mammals that inhabit Calakmul, five are felines, such as the puma and the jaguar. Calakmul is home to the largest population of jaguars in Mexico. The jaguar is very respectful and fearful of humans so it is very difficult to see one.
Some species of animals are more associated with bodies of water, locally called "aguadas" such as the white-lipped peccary and the "rare" tapir.
These jungles are a paradise for more than 350 species of birds, both permanent residents and migratory, which is equivalent to about 70% of all birds registered in the Yucatan Peninsula and one third of all registered in Mexico.
ORCHIDS AND OTHER PLANTS
The vegetation of the Calakmul region is composed of more than 1,600 species of vascular plants (representing more than 50% throughout the Yucatan Peninsula). Registered flora is composed of 153 families, 834 genera and 1,936 species, with an estimated endemism percentage of 10%. Added to this, in Calakmul there have been 73 species of orchids registered, of the 40 species that were known in the entire Yucatan Peninsula.
