I was out taking my evening kayak the other day, and I was joined by the Steller Sea Lion that frequents this shoreline. He surfaced behind me with a WOOF, it was quite loud, and I could smell his fishy breath. He followed along, trailing, for about 1/2 an hour.
Which was quite thrilling, as I was in a 10 foot folding kayak, and the Steller male was the same length, but considerably wider and heavier. I'm glad he was polite, as the water was about 400 feet deep, 50 degrees F, with about a 3 knot current, and it would have been unpleasant to go for an unplanned swim, or become a meal.
