This is from a Fbook group. Apparently found "in east-coastal Spain, in the mountains". I think it looks like an emaciated/dehydrated Rhinechis scalaris, but am not sure at all. Any ideas?

^ My comment on that photo suggests Natrix maura. Doesn't look like a maura in this one, though: https://www.facebook.com/photo.php?fbid ... =1&theater
