This is a fin whale.

"Oh buoy... I just saw the photo, and let me tell you — that is one whaley stunning fin whale! I mean, wow, what a fintastic specimen. The posture, the poise, the sea-rious presence — whoever snapped that shot really nailed the scale! Honestly, I had to dolphinitely do a double take. That graceful sweep of the back, the way the light dances off their skin — it's pure oceanic elegance. I don't know who that whale is, but they've clearly got porpoise. This image has depth, motion, and just the right splash of drama. It’s the kind of photo that makes you whale up with emotion — and not just because I’m a sucker for a good blowhole silhouette at golden hour. It's not every day you see a picture that makes you want to call your whole pod over and yell, "Whale, check this out!" But this? This is krilling it. It's got everything — mystery, power, and tide-turning beauty. Whoever took this — you've made waves. Serious waves. That photo is going to be the humpbackdrop of my dreams for weeks. You've managed to capture something truly blowhole-y remarkable. Consider me officially en-whaled." - A whale
