About Pelodiscus maackii (Brandt, 1858)
Pelodiscus maackii is an aquatic soft-shell turtle species. Adult individuals can reach a maximum straight carapace length of 32.5 centimeters, which equals 1.1 feet. This species is distributed across the Russian Far East, northeastern China, Korea, and Japan. Researchers think it is possible that the wild populations found in Japan originate from ancient human introductions.
