我的英语学习笔记: Koalas : when stupidity is a survival strategy.

Koalas  are not good fighters, they are not good runners and they are not good showboaters.

If they had to compete with other animals, they would lose in every category.

Lucky for them, they are unique in the animal world and face zero competition.

Why? well, it's because their food is toxic.They are one of the only species that can subsist on eucalypt  leaves alone.

And eucalyptus leaves are super toxic,consuming more than just 3.5 milliliters of oil can be fatal to humans.

koalas have guts of steel .They are able to digest toxic eucalyptus thanks to a specialized gut bacteria that they get from their mothers.

Not only is eucalyptus toxic but it's also not very nutritious, and so koalas need to eat a lot of it.
