Even released into the wild, Hermann's tortoises (Testudo hermanni hermanni) bred in captivity are often recognizable by the deformations of their shells. The most common deformities are bumpy shells and soft shells. The bumpy or toblerone carapace visible on this specimen is usually a sign of a poorly dosed diet of calcium and phosphorus, the ideal ratio being 1.5 to 4 times more calcium than phosphorus, and of a lack of water.
