Spotted pond turtles are divided into white-spotted pond turtles and yellow-spotted pond turtles, which are mainly distinguished by the color of the spots on their shells. However, because the spots on the carapace and marginal scutes of yellow-spotted pond turtles may fade, they are also distinguished by their lines.

As shown in the picture below, the white spots on the back of the pond turtle are on the rib shield? The lines are obvious and radial, radiating from the spinal scute to the marginal scute, but the ring-shaped pattern is not obvious. The lines on the carapace and rib shield of the yellow-spotted pond turtle are mainly circular, radiating from the spinal scute to the marginal scute, and the radial lines look like It is secondary. Judging from the differences in the origins and tortoise shell patterns of yellow-spotted and white-spotted pond turtles, perhaps these should be different species of the same genus. There is no reproductive isolation between the two, so white spots and yellow spots are inevitable in the artificial breeding process. Crossbreeding may be the reason why some yellow-spotted pond turtle hatchlings metamorphose into white spots. White-spotted pond turtles have been artificially bred for more than 10 years and have relatively accurate egg production/number of eggs/incubation temperature/sexual maturity cycles.

Is artificial breeding of yellow spotted pond turtles better? The upper white-spotted pond turtle may not be much different from the white-spotted pond turtle, but it is slightly more difficult. The biggest difference between the white-spotted pond turtle and the yellow-spotted pond turtle is not only the color of the spots, but also the shape of the carapace lines and the lines on the marginal shields (including the upper and lower marginal shields).
