I’m sure you’ve seen this before but it’s a really cool reference for how freaking big whales are. Obviously the whole “almost eating diver” thing is bs but it’s still a pretty cool video.
That’s a great size comparison. I can’t confidently tell what species these whales are, but uh… that’s why you don’t get in the water with whales. They’re eating the school of small fish, and the surface gape-and-swallow is a totally normal feeding strategy. That’s not something you want to be in the water with. They’d likely avoid ‘eating’ you because they’re filter feeders and you’d get stuck and be uncomfortable, but they’re still huge and covered in barnacles and able to stun you with a bump, and their mouths closing like that create quite a vortext of water that could knock a diver around.
(I’m not immediately inclined to condemn this video because something about their setup makes me think this might be a research team, although I can’t say quite what. However, it’s still a really risky thing to be doing even if there’s a legitimate reason).
