Rhino
So the Zhonghua Da Zidian 中華大字典 is available in its entirety on archive.org. This might be of interest even to those not committed enough to Chinese to read a dictionary from 1915, if only because of the many fine color plates at the beginning of the first volume illustrating some of the words for plants, birds, body parts, and so on.
The one for "animals" includes this distinguished example of I've-only-ever-heard-this-animal-described-but-I'm-going-to-draw-it-anyway (or possibly of this-is-how-we've-always-drawn-this-animal-and-I'll-be-damned-if-I-let-the-facts-get-in-the-way):
Yep, it's a rhinoceros.
Carl:
According to the dictionary, humans wear boxers when you see them from the front, but not from behind. Very mysterious.
