I am not sure what twisted dark omen this is but I am not with it! This looks like something off of AHS!!!
It appears as though the left head is more dominant – it’s generally more active and responsive to stimulus. Radiographs revealed that the two-headed snake has two tracheas [the left one is more developed], two esophaguses [the right one is more developed], and the two heads share one heart and one set of lungs. Based on the anatomy, it would be better for the right head to eat, but it may be a challenge since the left head appears more dominant.
