Did You Know?

The turtle exhibit at a zoo is often in the form of a terrarium, as are some of the exhibits at a plant conservatory. In an ant terrarium, elementary-school students watch the ants dig their network of tunnels as if no one were watching. Terrariums try to create conditions as close as possible to a natural habitat. A covered terrarium can often sustain itself for months on the moisture trapped inside. But creating a good terrarium requires careful control not only of humidity but also of temperature, as well as good ventilation; the lighting should include the full spectrum of sunlight as well as a day-night regulator.
