Their description is not known, but they appear to have been rabbits, which where unknown in the north-western regions of Middle-earth.[note 1] The lopoldi were voracious herbivores and multiplied easily quickly, so they were found in large numbers on Númenor. The Númenóreans did not view the lopoldi as food, leaving them to be the chief food source of Foxes, which were viewed as the best natural way to keep the lopoldi population levels under control. As a result of the abundance of the lopoldi, foxes never hunted animals domesticated by the Númenóreans. The lopoldi most likely perished during the Downfall of Númenor.
- Within a side note, Carl F. Hostetter compares the lopoldi to European rabbits, which came to northwestern Europe at a late date.
