The Pacific White-Sided dolphins are fascinating. They are common to see in recent years, but they weren't here much at all in the prior decades. They are regular sights in groups of dozens to fifty or more.
The experts say that in the "Straits" they are eating the schools of small 3 or 4 inch herring by constantly herding them. I was very skeptical about this when I first heard it a few years ago, but now I believe it. Just think of the amount of tiny herring that these numerous warm-blooded mammals must need. They work hard for their meals.
