Abstract

Pyramiding, is a condition in which the scutes of the carapace of turtles become deformed and elevated, taking on a pyramid shape. Pyramiding is believed to be a nutritional problem, however its exact cause is unknown. Given that the turtle carapace is composed largely of bone, it was hypothesized that it may be caused by an imbalance in dietary calcium (Ca) and/or phosphorus (P). Therefore, a study was performed to determine if calcium and phosphorus supplementation induced pyramiding in a group of young, rapidly growing turtles.
