Once I was walking a spit when a harbor seal popped out of the water, a huge salmon in its mouth. The salmon was thrashing about and its head and tail were taking turns hitting the sand. The seal was determined to hang onto it though and was doing a good job of it.

And then up came a self-important seagull strutting over the beach to the seal and its treasure. I don't know what the further develpments would have been because, salmon in its mouth, the seal slipped back into the water and disappeared.
