This reminds me, that an old name for a rabbit is a "coney", and an old name for a rabbit warren is a "coney-borough", a fortified town of rabbits. Over time, that became simply "burrow".
Or "bunny"? :-)
Of course, that word is of a completely different etymology (Scottish).
Which are, by the way, the closest extant taxon to the elephants. Which themselves are named just for their thick skin.
Meanwhile, "hare" (or "Hase" in German) remains also in English.
