Here's another photo from one of the heat runs earlier this week. It's a veritable wall of humpback whales...some diving, some swimming up, some probably not sure which way to go.

A wall of humpback whales
There was another whale below the six you can see in the image. He's the source of the stray bubbles percolating up from the deep.
