the situation is indeed incredible, but the video ? just a video
in description of this whale I found:
"After five and a half minutes the whale reaches five hundred meters (1640 feet). Humans can live and work down here but it takes days of compression to get there and days of decompression to get back." - do divers really work like this ? over 500m down, few days of deco ? wow
or "After eleven minutes (...) she is about 1000 meters (...) At this depth the air in the whale's body is one percent of its original volume, and it is 100 times more dense. "
"A typical dive lasts 60 minutes. No one knows how long a sperm whale can hold its breath but estimates range from 90 minutes to 2 hours." - so one hour is 'jus a dive' so what can be the record ?
and this I find amazing
