They're very close in appearance and anatomy to humans, but they have bioluminescent hair and skin, as well as black sceleras
They have Night Vision and live in dark caves
Hmm kinda remind me of those sea creatures in the midnight zone that glow. Also remind me of glowworms.
But I don't have and idea so idk why I commented sorry
I think I'm overthinking things and should just make them a different species of human
What do you think?
