The Parque Zoológico Internacional A.C. (PZI) shelters approximately 54 species of mammals, 120 species of birds and 16 species of reptiles. These numbers have increased over the course of the last 35 years.
To care for the animals the zoo has 30 employees (veterinarians, nursery personnel, maintenance personnel, etc.) qualified to work with the different specimens as well as qualified for the maintenance of the facilities and equipment. The zoo remains open 365 days per year.
The zoo has a nursery ward where visitors have the opportunity to touch and feed baby animals such as grey bears, black bears, Siberian tigers, lions, jaguars, kangaroos to mention only a few. Of the animals born at the PZI, many are sent in exchanged and/or sold to other national or international zoos.
There are educational guided tours for students and orphanages.
Currently, the guided tours have been suspended due to zoo remodeling; when finished, the doors will be opened again.
The zoo has been active with governmental agencies working to save and protect wildlife. An animal husbandry program for marine specimens such as seals, sea lions, etc. renders aid including treating skin cuts, food poisoning, hooks in mouths, harpoons, bullets, etc. The zoo also has programs in place to protect and aid confiscated animals.
