Free Admission Wednesday at Staten Island Zoo - see INFO below. The Staten Island Zoo is an 8-acre suburban zoo in West New Brighton, Staten Island, New York City. The zoo is open year-round except on Thanksgiving, Christmas, and New Year's Day. It has been accredited by the Association of Zoos and Aquariums (AZA) since 1988. The Staten Island Zoological Society created the Zoo with the founding principals that it be an educational zoo. The Society held monthly evening lectures at the zoo, provided lessons at local schools, and provided zoo tours for school children. Initially the focus of the zoo was reptiles, in particular including the collection of snakes housed in the zoo's Serpentarium. Although the focus of the zoo has broadened, the zoo's collection of rattlesnakes is still regarded as among the largest and most complete in North America. The current collection comprises over 1,500 animals of over 350 different species. Among the zoo's current exhibits is the African Savannah at Twilight. More Info below.
