Humpbacks are baleen whales, meaning they have huge baleen plates (made of the same stuff as your fingernails) in their mouths to strain out small fish and invertebrates from seawater. They open their mouths to let in huge amounts of seawater, then use their tongue to push the water out against their baleen plates. A big colander! I suppose the divers could have been sucked in with the fish, but whales are very intelligent, plus are equipped with sonar and surely knew they were there. Must have been a heart-pounding experience nonetheless, but ultimately very cool.
Thanks for the information! Indeed cool...
I would have had a terrible odor coming from my wet suit when I got out of the water and a shower would be needed afterwards. First, I would have said it and done it at the same time. WOW
