It subsequently forms an elongated gland with three coils or so round the adductor muscle on the left side of the body, but opening in the median ventral line.
If however the single muscle is an ancestral organ, it is important to observe that it entirely disappears as development goes on and the two adductormuscles in the adult are developed independently of it.
