A large frog 15-20cm
No interactions present.
Hi - from the pic I think it is a marsh frog (though there are five or ore very similsr taxa in the UK now, this is the most likely).
Thanks for ID confirmation and comments.
What are the other five or six taxa?
Rana esculenta and Rana lessonae seem like possible confusions but I cannot find any others (although my lists may be out of date).
Lat/Lng: 50.8, -1.6
