Historical information
The first platypus to be bred in captivity was at the Sir Colin MacKenzie Sanctuary (now known as Healesville Sanctuary) in 1943. The birth was mainly thanks to the efforts of David Howells Fleay who was the director of the Sanctuary at that time. It was approx 50 years until another was born in captivity. In 1998 another was bred at Healesville Sanctuary. Since then attempts at breeding platypus have been largely unsuccessful.
