In an update, Kleopfer said both heads appear to be capable of biting. Though, the Wildlife Center of Virginia in Waynesboro said in a statement, "It appears as though the left head is more dominant.
"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."
Kleopfer added in his Facebook post, "Wild bicephalic snakes are exceptionally rare, because they just don't live that long. Too many challenges living day to day with two heads." Kleopfer also noted that if the snake thrives in captivity it will be donated to a "zoological society."
