On Macquarie Island, in the Australian Sub-Antarctic, huge elephant seals snooze on the beach; their slumber sometimes disrupted by passing king penguins marching single-file up and down the beach. The penguins don’t seem to like having to alter their straight-line in order to avoid the elephant seals. They stop, and the lead penguin yells at the seal. I imagine they might be saying something like “your blocking OUR beach!”
