The horns can be used for different purposes. Sometimes the animal uses it to uproot small trees and shrubs, of which he likes to eat the roots, sometimes to clear paths thorugh the forest, and not in the least as a weapon.
Wunderlich has shown that the horns can be shed at regular intervals and then grow again. At first the spot where the horn is attached looks like a wound and can be recognized by a lot of blood vessels. The new horn grows again slowly. This has only been witnessed in the Indian rhinoceros, not in any of the other species.
One shown since pentecost 1927, 1 yr old male, 'Faru'. It was caught by Christoph Schulz in the former Deutsch-Ost-Afrika [Tanzania]. It plays the whole day with the animals with which it came, a monkey (Cercopithecus nictitans), a young riverhog (koiropotamus porcus daemonis) and a longear-goat. First bicornis in Frankfurt was 'Drucy'
formerly the zoo had an Indian rhino.
One of two animals seen after WWI in this zoo.
