If anyone was wondering, this creature naturally has no dorsal fin rather than the fin being cut off on porpoise.

Unfortunately the Baji - the dolphin Douglas Adams wrote about in "Last Chance To See" - is supposed to be extinct since 2007 (according to Wikipedia)

Freaky. I just finished watching an episode of Extraordinary Attorney Woo last night titled 'Yangtze River Dolphin'. No doubt Attorney Woo would be very pleased to hear this news.

What is the porpoise of having no fins or have they not evolved having them yet?

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.

Did the porpoise figure out how to thrive on human waste? Is this the purpose of the porpoise?

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