Between 1963 and 1974, all 14 adult tortoises discovered on the island were brought to the tortoise center on Santa Cruz and a tortoise breeding program was initiated. In 1977, a third Española male tortoise was returned to Galapagos from the San Diego Zoo and joined the breeding group. [ 78 ]
Most species of tortoises lay small clutch sizes, seldom exceeding 20 eggs, and many species have clutch sizes of only 1–2 eggs. Incubation is characteristically long in most species, the average incubation period are between 100 and 160.0 days.
The tortoises grow faster when there is more rainfall and slower when there is less. [6] They reach sexual maturity after 10 to 15 years. In captivity their life span is around 54 years. In the wild their lifespan is unknown but is believed to exceed 75 years. [10] [6] The tortoise has no known predators when they are hatchlings or adults. [6]
