  1. Breed reptiles in captivity: Tortoises, terrapins, side-necked & softshell turtles

    A study in 1975 at Philadelphia Zoo, USA (Bowler 1975) reported that Galápagos giant tortoises Geochelone elephantopus produced one hatchling in captivity. A clutch of nine eggs was produced, one of which hatched successfully after an incubation period of 200 days. The hatchling had to be removed from the egg by hand. Four eggs were broken in the nest, and five were placed in the incubator, of which three were fertile. One was opened after 143 days and found to contain a live embryo, and one was opened after 211 days and contained a dead embryo. The adult male had been in captivity since 1928, and the adult female was hatched in captivity in 1940. Eggs were incubated at 26.7°C.
