What a Caul is not
There are many misconceptions about the exact description of a caul. Other phenomena which are often mistaken for a Caulbearer birth are as follows.
En-caul births: Some children are born while still enclosed within the amniotic sac or membrane, the amnion, which surrounds the newborn. This usually entails the child being born with a sac of transparent or translucent membrane surrounding all or part of the child. This phenomenon is referred to as being born en-caul, which is the medical term for such births, as in the general sense the words caul and membrane share the same common description. Here is a link to a photo of an en-caul birth and one to a video of an en-caul birth.
As mentioned previously, this is not a Caulbearer birth, and is one of the most commonly held misunderstandings of being born with a caul, as the word caul is often used to describe a covering or lining.
