Water: While koalas primarily get their hydration from the moisture content of eucalyptus leaves, they do occasionally drink water, especially during hot weather or when the eucalyptus leaves are particularly dry.
What do koals like to eat and drink?
Eucalyptus leaves: Koalas are almost exclusively leaf-eaters, and their diet consists almost entirely of eucalyptus leaves. Different koala populations may specialize in different eucalyptus species, and they have a highly developed sense of smell to help them select the leaves with the highest nutritional value.
