Pachytriton changi is a species of salamander in the family Salamandridae from Guangdong, China.
Salamanders are a group of amphibians typically characterized by a lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All present-day salamander families are grouped together under the order Urodela. Salamander diversity is most abundant in the Northern Hemisphere and most species are found in the Holarctic ecozone, with some species present in the Neotropical zone.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Currently, 74 species have been identified in the Northern Hemisphere - Europe, Asia, the northern tip of Africa, and North America. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves.
Guangdong is a coastal province in South China on the north shore of South China Sea. Its capital of the province is Guangzhou. With a population of 113.46 million across a total area of about 179,800 km2 (69,400 sq mi), Guangdong is the most populous province of China and the 15th-largest by area. Its economy is larger than that of any other province in the nation and the 6th largest sub-national economy in the world with a GDP size of 1.47 trillion US dollars in 2018. The Pearl River Delta Economic Zone, a Chinese megalopolis, is a core for high technology, manufacturing and foreign trade. Located in this zone are two of the four top Chinese cities and the top two Chinese prefecture-level cities by GDP; Guangzhou, the capital of the province, and Shenzhen, the first special economic zone in the country. These two are among the most populous and important cities in China, and have now become two of the world's most populous megacities.
