I love love love this flowchart of what animals are called in German. It's hilarious and very informative, too!
We were chatting with a German friend and said that there are quite a few pig and bear derivatives. Noo, he said. Our friend said, "Racoon?"
"Waschbär." This is literally "wash bear." Hilarious.
My favorite two names (I couldn't pick just one) were the Faultier ("lazy animal," or sloth) and the Nacktschneke ("naked snail, or slug). I love how descriptive the German language is!
