The red veins is interesting because this suggests it has changed from green copper-rich fluid to hemoglobin based. These are the UFOs responsible for cat and cattle mutilations. It’s these that have evolved into Mothman-type entities. Fantastic details. Thanks for sharing. Please Register or Log in to view the hidden image!
