Animals Zoos Cages Large Types Things People Separating

There are many different types of zoos in the United States. A "traditional" (common; as things were done in the past) zoo has animals in many different cages, and people walk along paths between and around those cages to view the animals. Modern zoos try to "alter" (change) the cages to "imitate" (copy) the animals' natural habitat. For example, the metal bars of cages are hidden behind "vegetation" (plants) and "concrete" (cement) "barriers" (objects separating things from each other) are "disguised as" (made to look like something else) "boulders" (large rocks).

"Open-range zoos" "take this a step further" (continue an idea, pushing it further) by putting animals in large, open areas, but not in cages. The areas are "fenced off" (with separating walls) to prevent predators from being in the same area as their "prey" (the animals killed and eaten by predators) and to prevent them from leaving the zoo. But within those large, fenced areas, animals of different "species" (types of animals) can interact. Because open-range zoos are very large, people visit them in a vehicle, either by driving their own car on paved roads or by riding in a special type of car or bus.

"Petting zoos" are smaller collections of "domesticated animals" (animals that are used to being around humans, especially on farms) like rabbits, goats, chickens, and sheep. Young children are able to enter the "pen" (a cage without a ceiling) with the animals and "pet" (touch) them or even feed them.

An "aquarium" is a type of zoo for viewing and studying "aquatic" (relating to the water) life, often "undersea" (in the ocean) plants and animals.
