Chinese Soft-Shelled Turtle pictures (Pelodiscus sinensis). They are endangered.
This species is native to China, Taiwan, Korea, Manchuria, North Vietnam, and Japan. They have also been introduced to Singapore, Thailand, Batan Islands, and California. The adults are usually about 14 inches long.
Turtle soup is made from this species, but they're not popular as pets. Asian cultures believe the turtle has strong medicinal powers. THey have elongated, soft, snorkel-like nostrils. Their necks are disproportionately long in comparison to their body size, enabling them to breathe surface air while their bodies remain submerged in the mud or sand, sometimes as much as a foot or more below the surfcae. Like some amphibians, they are able to extract a small amount of oxygen out of water via their skin, futher enabling them to stay underwater for prolonged periods.
