Same reason argonians have mamaries: to blend in and ease introduction to other species....why does something not in the taxonomical Class Mammalia have mammary glands?
Clearly within Superclass Tetrapoda, Class Amphibia.
But arguably Superclass Osteichthyes, Class Sarcopterygii.
However both Class Amphibia or (either Class of *-finned fish) absolutely lack mammaries.
This is why Cladistics is superior to Taxonomy. (IYKYK.)
...because it natively supports Fantasy waifus.
