The Thursday Challenge for today is a picture that evokes the idea of sound. So I'm choosing this one: a humpback whale crashing back down after breaching.
Don't forget to hear the excited oohs and ahhs of the passengers. We found two whales who were just diving, but then they started breeching and they did so for twenty minutes straight. Everybody got a great picture.
Have whales learned to perform? Do they realize if they just jump around a while, we get all excited and then go away? Are they dislodging plankton after they've fed? Is it something that helps their digestion? Or is it just fun, a pasttime on a lazy warm Alaska afternoon? The whales ain't talking to us about it.
