This constellation is unique among all others. It is the only one, which consists of two parts: Serpens Caput, the Head of the Serpent and Serpens Cauda, the Tail of the Serpent. Between both parts lies the constellation of Ophiuchus, the Serpent Holder.
Although Serpens Caput and Serpens Cauda are really separated, they count as one constellation.
