Mermaid gargoyle

I was back in Christchurch today to pick up my glasses from Specsavers. Took a walk to the Priory to view the gargoyles and grotesques, some of which are new and/or have been cleaned up.  Apologies to anyone of a sensitive nature.  This one is slightly indecent.  
Useless piece of information: If the carving is attached to a water pipe it is a gargoyle.  If not it is a grotesque.
