This freshwater turtle was split from the New Guinea snake-necked turtle and regarded as distinct species in 1994 after Dr. Anders Rhodin, director of the Chelonian Research Foundation in Lunenburg (Massachusetts), found out that there are differences between the two species. The first snake-necked turtles on Roti Island were discovered in 1891 by George Albert Boulenger. They were named for Dr. William McCord, a veterinary and turtle expert from Hopewell Junction, New York.

A clutch can consist of 8 to 14 and it can have three breeding periods in one year. The size of the eggs is 30 x 20 mm and the weight can reach eight to ten grams. The first hatchlings come after three months, the last after four months. When they hatch they have a size of 28 x 20 mm and they have yellow spots on the plastron which become darker with the time until the plastron becomes almost black after a few weeks. During the growing period the coloring becomes more pale until they finally reach the color of the adults.
