Koalas are fucking awful animals though. The proportional size of the koala's brain to the rest of its body is one of the smallest among mammals, plus their brains are SMALL. The brain is corrugated as we know it to increase the usable space for neurons.
If you show a koala leaves picked from a tree and placed on a flat surface, the koala will not recognise them as food. Koalas are too stupid to adapt their eating habits to cope with any change. In a room full of food they can literally starve to death because their brains are so incapable of dealing with change, this is hardly the mark of a winning animal in life and in the struggle for survival.
Speaking of stupidity and food - one possible reason why their flat brains are so primitive is that eucalyptus leaves are not only poisonous (the only thing they eat) but also have virtually no nutritional value! They simply don't get enough energy from them to think, they sleep more than 80% of their fucking lives. When they are awake, all they do is eat, shit and sometimes scream like little fucked-up demons.
Since eucalyptus leaves have such a low nutritional value dear koala bears must ferment them in their guts for days. Among mammals, the proportion of their digestive system to their entire body is one of the largest. Many species of herbivorous mammals are adapted to cope with unfavourable plants acting on their teeth, rodents, for example, never stop growing teeth, some animals have teeth located only in the lower jaw and crush plant tissue on their reinforced palates. Still others have enlarged molars to grind plant matter more impressively. Koalas are of course no exception and when their teeth turn to dust they solve the situation in a very simple way - they simply starve to death because they are absolutely hopeless animals.
As mammals, koalas feed their young with milk, of course (it is worth noting that among mammals they give the least milk in relation to their body size). When the young has to switch from the rich and nutritious food which is milk to eucalyptus leaves (a plant which makes it clear that it does not want to be eaten), it turns out that it is not adapted to this at all, because it does not have in its intestines the bacterial flora necessary to digest this rubbish. The solution? The cub quite literally starts to rely on its mother's ass, which has to shit out some of the less digestible eucalyptus, and then it sips it with pleasure and thanks to this it can start to adapt its digestive system to this wonderful diet.
Of course, the cub may have also swallowed some pee, because its mother probably does not hold her urine properly. Why? Because she is probably suffering from some kind of venereal disease, just like the rest of these animals. In some areas the incidence is something like 80% or more. Because, you see, one of the activities that koalas devote their precious energy to is rape. Although koalas breed seasonally the males either don't know it or don't give a shit and just rape the female regardless of whether she's in her cycle.
If the female comes flat-brained to defend herself, the male may want to throw her off the tree (and fall with her of course) which brings us to the last interesting fact about the brain of this idiot species.
Koalas have an above-average amount of cerebrospinal fluid in those nasty heads (they have a lot of space there that they have saved for neurons). Why do they have more of it? To protect their brains from injury in case they fall off a shitty tree full of toxic worthless leaves.
An animal so fucking stupid it has its own little safety helmet built into its brain. How I fucking hate them.
