RH NEGATIVE REPTILIAN? OR FROM ANOTHER ANGLE MERMAIDS

Iron blood:
🦆most mammal and birds blood is red because of hemoglobin, whose protein is made of hemes, or iron-containing molecules that fuse with oxygen.

Copper blood:
🐙Octopuses, slugs, and horseshoe crabs have blue blood because the protein transporting oxygen in their blood, hemocyanin, contains copper, instead of iron.
