Founded in 1927, the zoo is home to a wide selection of mammals and reptiles of the North America region, including some endangered species. At one time, Space Farms was host to the largest bear in captivity in the world, a Kodiak Bear named Goliath. The 2,000-pound (900 kg) Goliath still stands tall in front of a diverse taxidermy exhibit in the main hall of the museum. He was preserved in an imposing upright position after his death in 1991. His abnormally large skull is upstairs, where one can compare it to skulls of other animals.
The Space Farms museum houses an extensive variety of antique vehicles and items used during the early history of the United States, such as horse-drawn carriages and early motorcycles. The vehicles are largely unrestored, being in much the same remarkable condition as when they were acquired. There are also colonial period tools and weapons on display.
Children can feed young animals by hand and there is a large food and drink area for picnics. There is also a gift shop and playground area where people can explore nature without being in the wild. The atmosphere is very relaxed, with family members giving talks and performing (animal) infant feedings.
