I've gone on a few trips with Captain Dave, and they're awesome.
Also shown here, similar drone footage off Maui.
In one video: "A huge mega-pod of thousands of common dolphins stampeding off Dana Point, California, three gray whales migrating together down the coast off San Clemente, California, and heartwarming close-ups hovering over a newborn Humpback whale calf snuggling and playing with its mom as an escort whale stands guard nearby."
And in another, the beautiful, rare, and endangered blue whales who have recently arrived in Dana Point, California. And "Gray whale moms and babies playing in surf and kelp off Orange County. And lastly, watch a huge megapod of several thousand dolphins tightly concentrated and swimming next to our whale watching boat from the air."
