A soft-bodied reptilian robot, modeled after a crocodile, which can conduct different operations in complex environments above and below water, has made its debut at the 25th China Hi-Tech Fair (CHTF) in China's southern tech hub of Shenzhen.

The fair, which runs from Wednesday to Sunday, covers an area of some 500,000 square meters, and has gathered 4,925 enterprises from 105 countries and regions, making it the largest ever edition.
