Dr. Juan A. Rivero Zoo (sometimes called Mayagüez Zoo) is a 45-acre (18 ha) zoo located in Mayagüez, Puerto Rico. It is the largest zoo on the island. It is named in honor of Juan A. Rivero, its first director. It has an extensive collection of animals from all continents. The premises of the zoo have remained closed to the general public following the passing of Hurricane Maria over Puerto Rico in September 2017. From Wikipedia
