An extinct or rare wild ass-like animal from Central Asia, also known as the half-ass or kulan.
From Greek hemi- (half) + onos (donkey or ass), literally 'half-ass,' named for its intermediate size and characteristics between horses and donkeys.
The hemionus was named by ancient naturalists who didn't quite know what to make of this creature—it's fast like a horse but sturdy like a donkey, so they called it 'half of each,' which is actually wrong since it's a distinct species.
