@Leucrotta Are coelacanths also an acceptable topic?
@GraySpots @Leucrotta I dunno, Rin, lobed fishes like coelacanths are more closely related to humans than to bony fishes.

@GraySpots @Leucrotta We're all fish! Four-legged creatures are all descended from a tree that arose from the lobed-fin fishes. :)

the color is 'cause the oxygen carrying thing is hemocyanin which is copper based instead of iron!
