In the eastern Australia, on the edges of rivers and freshwater lakes you can find an infamous animal called "the platypus". Platypuses, also called platypi, are mostly active for several hours after dusk and a few hours before dawn. And during the day time you can't find the platypus swimming around, because they are resting in there burrows in the river bank, but sometimes it comes out to the burrow entrance, basking in the sun and grooming it's dense fur.
