Abstract     
Testudinidae Geochelone A possible correlation of egg mass with female body mass was examined in Astrochelys radiata, a tortoise species endemic to Madagascar. Data from a wild population were compared with observations from captive individuals. Nesting data and egg mass were related to female body mass. Females from the captive population were significantly larger than those in the wild. They also produced significantly larger eggs with larger mean egg mass. Regular feeding and access to a water supply in captivity may have enabled these females to be highly productive during the breeding season.
