Females tip their heads downward to browse on smaller trees while males reach upward toward tops of taller ones. This lessons their competing for the same leaves and branches. Giraffes can reach up to 20 feet high. As you can see, not all animals are in separate cages. Many animals are integrated just like in the wild.
Meerkats are active and highly gregarious.
They live in groups, unlike most small carnivores. A group of meerkats can successfully discourage predators. They also cooperate in caring for their young. But they do not hunt cooperatively. Meerkats are members of the mongoose family-capable of damaging Hawaii's native wildlife should they escape and become established.
