The saguaro cactus is the largest cactus in the United States. The tallest one measured was more than 78 feet (24 m) tall. This cactus depends on the lesser long-nosed bat for pollination. Its white flowers open up at night. The flowers attract the lesser long-nosed bat with a strong odor.

Many bats cannot fly off from the ground. They drop from high up and flap their wings. These wings have the same bones that humans have in their hands. The bones help bats save energy as they fly. Bats can change the shape of their wings. They try to catch as much wind as possible. The wind lifts and carries them through the air. Bats do not have to flap as often.
