Bibi and Poldi the tortoises (torti?) have been together at the Austrian zoo in Klagenfurt for 36 years, before that living together at the Basel zoo in Switzerland. No one is sure exactly how long their marriage has lasted until now, but zoo boss Helga Happ says that they met when they were "young," so it's safe to say that their 'marriage' has passed the century mark.
Bibi attacked Poldi several times before he was moved to a separate enclosure to protect his own safety. Happ said "We get the feeling they can't stand the sight of each other anymore." Experts have been called in to feed the pair aphrodisiacs and get them to play games together, but to no avail so far.
