Sorry, this is probably the wrong thread to ask, but can't think of anywhere better. I've just had a phone call from my Mum asking me the question above: I suggested perhaps baby otter (too big and in suburban Manchester so she doubts it), water rat (she says no) water vole (too big),stoat (?), weasel(?)...she says it has an otter like face, appears to be black (but then again it is wet) and keeps jumping in and out of the pond (a big-ish one 12ftx9ft)she hasnt seen it catch a fish and the fish dont seem too perturbed (but they sat like peace offerings for the heron until we had to fence them in or lose them all) so does anyone else know what looks like a little otter and swims around suburban ponds?
