Popping a male sand boa baby

ID: Popping a male sand boa baby

Remarks:
This is illustrated by the closeup view of the cloaca of a newborn East African sandboa being popped to determine sex. The hand on the right side of the photo holds the body, while the thumb of the hand on the left side of the photo applies pressure to the base of the tail. One of the tiny hemipenes is shown fully everted, demonstrating without a doubt that this is a male. More pressure would evert the second hemipenis, but this is unnecessary.
