Maybe this was common knowledge to some folks but I only learned today that koalas have so little cognitive power, they won’t recognize leaves as food if they’re not on a tree branch. They have almost 0 learning capability or problem solving ability.
For years people thought that you couldn’t keep koalas in captivity because they were just ‘too sensitive’ and ‘meant to be wild’
Then they realized that the koalas literally just couldn’t figure out that leaves in a bowl were food
Apparently the koala’s brain represents only 0.2% of its body weight, the lowest of any mammal. In addition, it occupies only 61% of its already unusually small skull cavity, it’s completely smooth all over and there’s a big hole through the middle where the lobes never connect.
