Transcription

Description

P. steindachneri exhibits sexual dimorphism. Females of this freshwater turtle reach up to 44.5 cm (17.5 in) in straight carapace length, while males only reach up to 36 cm (14 in). However, males have a longer tail than the females.^[7]

Etymology

The specific name, steindachneri, is in honor of Austrian herpetologist Franz Steindachner.^[6]

Geographic range

P. steindachneri is native to southeastern China (Guangdong, Guangxi, Guizhou, Hainan, Yunnan), Laos, and Vietnam, but has also been introduced to Hawaii and Mauritius.^[3]

Threats

P. steindachneri is endangered by poaching for human consumption. Although pressure on the wild population continues, several thousand are hatched and raised each year on turtle farms in China and Vietnam for food and traditional medicine.^[8]^[9]
