Dolphin released back into the wild after a three-month effort

Over the following months, the dolphin regained normal behavior, began feeding independently, and showed restored blood biochemistry.

On Sept 8, an expert review evaluated Wanwan's daily feeding, endoscopic and ultrasound examinations, blood tests, and behavioural observations. Experts also observed the dolphin's swimming and feeding behaviors onsite and found no abnormalities, concluding that the dolphin met the conditions for release back into the wild.
