African Side-Necked Turtles: Pelomedusidae
Behavior And Reproduction
Although these side-necked turtles can be quite noticeable in their habitat, scientists know very little about their behavior. The turtles bask, spending warm days sunning themselves near the shoreline. They are especially active during the wet season, when they may roam over land. When the weather turns dry, many side-necked turtles seek shelter underground. Those that live in the cool, mild climate of the far south of Africa may hibernate, or become inactive, on land or under water through the winter months.
These turtles breed during late spring or summer, with the females laying six to four dozen oblong-shaped eggs. Scientists suspect that the turtles may have more than one set of young every year. The outside temperature controls how many eggs in a clutch, or group, will develop into males and how many will develop into females. Scientists call this "temperature-dependent sex determination," or TDSD. If the weather is constantly warm or especially cool, most of the young are females. If the weather is more temperate, or mild, most are males.
