1.KOALAS
Koalas mostly eat
eucalyptus leaves.
Thesehave a high water content, so koalas hardly need to drink. This lets them
stay in the trees, safe from predators.
2.ENERGY
But eucalyptusis a low energy food. Even though koalas eat over 1kg of leaves per day, they must spend 18-20 hours a day sleeping, to conserve energy.
3.BRAINPOWER
Their low-energy lifestyle
means koalas can’t sustain a large brain. At just 0.2 per cent of body weight, koala brains are one of the smallest of any mammal.
4.TABLE MANNERS
Their tiny brains can’t deal with
unfamiliar situations. If you give koalas eucalyptus leaves on a flat surface, like a plate, they won’t recognise them as food and won’t eat them.
