Blue-tailed stone dragon, also known as Liwen stone dragon in Taiwan. It is a species belonging to the family Lithopodaceae. Its larval tail is characterized by the blue color of the tail and the five longitudinal stripes on the back. But these 2 features will disappear after adulthood
Sexually mature individuals have significant differences in body color, with adult males having significantly larger body lengths, head lengths, and head widths than adult females. There was no significant difference between the sexes in the growth rate of juvenile body length, and the growth rate of adult males was significantly greater than that of adult females, so the sexual heteromorphism of individual size occurred after sexual maturity
Juveniles with a body length of less than 50 mm have no gender differences in head length and head width; when the body is older than 50 mm, the growth rate of male head length and head width with body length is significantly greater than that of females, resulting in head size and sexual heteromorphism, and becomes more and more pronounced with ontology
Blue-tailed dragon females increase reproductive output mainly by increasing the number of eggs in the nest and the size of the eggs. An insect-based daily lizard that lays 2 eggs at a time. This is an extremely widely distributed lizard. They are cold-blooded reptiles
The smallest body length of the egg-laying females is 69.3 mm, and females larger than this body length all lay single clutch eggs per year. The number of follies, fovular egg weight and mean egg weight were positively correlated with female body length, with means of 6.4, 2.783 and 0.554 g, respectively. The number of nest eggs is independent of the female's postpartum status
They are included in the Red List of Biodiversity in China, the Vertebrate Volume, with an assessment level of vulnerable. It is common in Lianghu, Liangguang, Anhui, Fujian, Sichuan, Liaoning and other places. Taiwan, Japan's Ryukyu Islands, Vietnam (my hometown also has it, I would like to see you)
