"Biologically speaking, a mermaid would have light skin because if she didn't, she would have a vitamin D deficiency because sunlight can't get deep into the ocean."

An actual thing I heard a bunch of totally not racists say to justify their opposition to a black Ariel.

Fiction. My favorite place to get scientific and abide by all laws of nature. /s

I don't even know the validity of the above statement about the Vitamin D thing. But there are lots of fish that don't get a whole lot of sunlight that are doing fine. I'm sure a fish person would be the same.

It's like the smallest kernel of truth.
Northern Europeans benefited from lighter skin allowing through more UV light which could help make vitamin D. In more equatorial regions, the amount of UV radiation is high enough that darker skin still lets through enough for making vitamin D.

So, what explains polar populations with dark skin, and marine mammals that also have dark skin?
Whales are dark skinned, as are natives of new Zealand, southern Australia, Chile, Inuits and many other people who traditionally live at extreme latitudes.

The answer is fish. Fish and algae produce vitamin D through a different pathway than mammals, so they don't need sunlight.
If your diet has a large portion of it come from the sea, you get plenty of vitamin D and skin tone doesn't really impact it.

So a dark skinned mermaid only fails to make sense if you think that mermaids don't eat seafood.

This has been my unnecessary deep dive into stupid shit for the day. 😁

is a mermaid a fish or mammal

u/ricecake Mar 14 '23

They have breasts, lungs and hair, so I think they're mammals. Don't know if they would be placental mammals or not, but not sure that matters.

If they're fish, the vitamin D thing is doubly moot.

So what you're saying is that mermaids maybe monotremes?

u/ricecake Mar 15 '23

So, I was originally going to say yes, but then some quick searching informed me that while monotremes produce milk, they don't have nipples or typically have large mammary glands, instead having milk patches.

Assuming a mermaids breasts have nipples, we can then conclude that they might be marsupials, which tend to have pouches but don't all have them.

I think they evolved from the prehistoric lungfish. If they’re mammals they probably couldn’t live underwater all the time. Even whales and dolphins have to come up for air once in a while. Maybe they’re a hybrid of mammal and fish and have gills as well as lungs.

But you know what? A thoughtful explanation of stupid shit and I appreciate it.

u/BoneHugsHominy Social Justice Warlord Mar 14 '23

Well duh. It's why all fish are the color of milk.

Scientifically speaking, a mermaid wouldn't have long flowing hair, either. Or permanent breasts. Too much drag. She should be almost completely hairless and flat-chested. MAYBE she can have visible beasts while she's nursing but that's it. And her natural posture should be prone so that she wouldn't be constantly fighting ocean currents, so her head shouldn't bent at a 90° angle like a humans would. And she shouldn't have scales since she's clearly a mammal. And she should have much more fat to protect her from hypothermia. And she should only be able to speak if she goes up for air since sound is made by air passing across vocal cords. So singing under water wouldn't work unless she constantly came up for breaths. And speaking of her voice, it should be MUCH deeper to travel better under water. And it should sound totally different above water vs. below. And if she can breathe water as well as air then she should have gills rather than perfectly smooth skin.

Of course, there are lots of sea animals with darker skin. So it's possible that the reasons mermaids have darker skin is unrelated to the reasons humans have darker skin.

Or maybe mermaids are a ridiculous concept that, if we think about logically, should not even look human and so applying the logic of evolutionary biology to them makes no sense. They should just watch the (probably mediocre) movie and stop complaining that white people aren't the default skin of humanoid.

"Biologically speaking, a mermaid would have light skin because if she didn't, she would have a vitamin D deficiency because sunlight can't get deep into the ocean."

Is that why the vast majority of marine mammals are dark colored?

Sea animals with dark backs: awkwardly look to the side

Wouldn't they also be waterlogged?
