They have boobs, so they must be mammals. - Victor Ganata

What Gee Dub said. - Rahsheen?

Platypus is an egg laying mammal. - Gunnyman™ from FFHound!

Yeah, but platypuses don't have boobs. My theory is that, while not all mammals give live birth, all mammals with boobs do. - Victor Ganata

Strike that, platypuses don't have nipples. So I guess it depends on whether or not mermaids have nipples :D - Victor Ganata

I believe the doctor. - Bruce Lewis from iPhone

Just to warn you, I'm not that great with non-humans :D - Victor Ganata

Like werewolves I think they propagate by a virus, though their's is passed via a tale swipe. - Todd Hoff

The platypus has mammary glands, though. - Headless Gnad Kicker

I still stand by my nipple theory! We need empiric evidence! - Victor Ganata

From Wikipedia: Monotremes lay eggs. However, the egg is retained for some time within the mother, who actively provides the egg with nutrients. Monotremes also lactate, but have no defined nipples, excreting the milk from their mammary glands via openings in their skin. - Headless Gnad Kicker

I do like Todd's theory of fish-based lycantrophy, though. But it could be cetacean-based lycantrophy instead. - Victor Ganata

I realize all the art work makes it ambiguous whether or not mermaids have nipples, but I still think all mammals with nipples give live birth. - Victor Ganata

Mermaids harvest men, as there are no males, for their bodies, seducing them and then implanting the egg within. As it grows it takes aspects from both the mother and the host. - Jimminy IS Everybody

That is absolutely terrifying, Jimminy. I guess they're kind of like wasps. - Victor Ganata

I don't have any real knowledge of mermaids, but I'm basing that on the fact they drag men to watery graves and I don't think they feast on them. What other use would there be? Some sort of sick glee from killing? - Jimminy IS Everybody

Killer whales at least do seem to enjoy killing baby seals for sport, so maybe this is evidence of cetacean ancestry :D - Victor Ganata
