When this elephant seal strayed on to their bit of the beach, these penguins weren't going to take it lying down.
As a result, the young seal suffered a painful pinch on the behind as the gentoo penguins on Antarctica's South Shetland Islands saw off the intruder. Clearly, the peck to the bottom hurt as the seal titled its head back and cried out in visible pain.
With space on the shoreline limited, such encounters are inevitable and the penguins appeared eager to lay claim to the pebbly beach.
The other penguins seemed rather unperturbed by the seal cry, with only one gazing up to witness the action.
