It's not every day a farmer finds a fur seal in his paddock.

But for Eric Neumann, Tuesday was that day. The South Australian farmer - from Bletchley, about 40 kilometres from the sea near Adelaide - noticed his cows acting strangely, and realised why when he saw the brown seal sitting next to a fence.

It's not known how the youngster found itself at Bletchley, which is a long way from the Murray River mouth's Lake Alexandrina (20km) and the ocean (40km).
