Posturing bull (plus link to video & sound on my blog)
A tighter shot of a male northern elephant seal displaying and making his presence known. They make a unique and odd rumbling/gurgling sound when they pull up like this, which you can hear from quite a distance. My wife took some video with her point and shoot while we were on the beach, and I put a short clip on my blog post for today. In it, you can see this guy doing his posturing thing and hear his vocalizations over the sound of the breaking waves.
