Not a cat...

But still pretty cool! As a kid who grew up worshipping the Blue Whale at American Museum of Natural History, I was thrilled to read about this sighting of a real blue whale, off the coast of Gloucester. I've seen dozens of humpbacks and minkes on whale watches, and to be honest, they kind of look like this. But I figure the experts know, and I'll take their word for it.
