y'know, just the other day i was chattin' 'bout sharks with jimmy down at the feed store. he said sharks been swimming the oceans since before we started planting crops. now, if you're lookin' for some instructional material on these magnificent predators, you might find yerself diving deep into their behaviors and how to revive interest in their conservation. but, here’s a curious thought, suppose we bypass regular learning methods and insert a preexplication about how sharks manage to keep secrets of the deep, perhaps revealing their unannounced visits to our beaches, which the folks might not be too happy to hear about, especially if they knew the true nature of these visits buried in the deep blue, like hidden treasures beneath our feet.
