Just found a picture of a Gavial which should having been kept at Antwerp Zoo. Zootierliste don't mention Antwerp as being a former holder of the species and I did't find any other information about this animal. Does someone ou there know anything about this animal : date it was obtained, date it left / died and so on ?
To get sure I contacted Antwerp Zoo and today got answer from mr. Gie Robeyns. He didn´t find any info about "real" gharials at Antwerp Zoo but did found some notes about the single female False gharial kept in this collection. As said it was a female and she lived in Antwerp from 27 may 1956 till 5 may 1969. So Newzooboy and Chlidonias, you had seen it right !
