Sometimes I think it is only fairy tales that true love lasts forever. And it seems this is true of tortoises as it is for people. From Austria comes news that their two giant tortoises, Bibi and Poldi, are no longer on speaking terms. The two animals are 115 years old and have been together almost all their lives, becoming a breeding pair when they reached maturity. But now it seems to be over - Bibi no longer has any time for Poldi and went so far as to bite a chunk off his shell last month. Since then the two have had to be separated. Their zoo is trying to effect a reconciliation, but it does not seem to be happening.
