Blue whales have a distinctive spout, one that you'd expect from the largest animal ever to have lived on the planet.
Blue whale (Balaenoptera musculus) spouts go high in the air
Blue whale spouts are unmistakably tall, shoot straight up, and are a cinch to spot from far away (assuming there's minimal wind, of course).
Despite facing challenging conditions (in the form of ongoing strong winds), I've had the good fortune of seeing dozens of blue whales up close during my virgin visit to the Sea of Cortez.
I still have a few more days left before I head Down Under to seek out the company of sea lions. Though the winds are forecast to continue, I'm keeping my fingers crossed for continued good luck.
