- Abstract
The Japanese sawback turtle is a small marsh turtle that is found on the Ryukyu Islands in Japan. It prefers moist habitats and can be found in primary and secondary forests. The turtles are threatened by habitat loss and the development of new agricultural land. In captivity, they are fed a variety of animal and plant-based foods. Mating and egg-laying occur on different levels of a terrarium, with an egg-laying box set up for each female. The terrarium consists of a plastic box with drainage holes, filled with pine mulch and sphagnum moss. There is also a halved box that serves as a cover. The terrarium has a water basin with surface drainage and a plastic tank for water storage. An automatic irrigation system has been installed to regulate humidity. The turtles are kept individually to prevent egg breakage and to assign the clutches to their respective mothers. Since the installation of the irrigation system in 2014, mating and fertilized eggs have occurred regularly. The turtle eggs are elongated and relatively large. The table contains data on the laid eggs from 2015 to 2020. The incubation period varies between 65 and 83 days, and the genders of the hatched animals appear to be male regardless of the incubation temperature. The authors emphasize the importance of protecting this endangered species and the efforts to enable their reproduction in human care.
