The Yangtze River dolphin is actually a different species & is sadly (most likely) extinct.

No, having no dorsal fin is perfectly natural for this species.

It's not going to be released into the wild, but rather a wildlife sanctuary.

Their dorsal fin was modified into a dorsal ridge that is covered in varying rows of tubercles. These tubercles are used as a sensory organ, as well as to move through the water.
