Humpback whales are forming super-groups

3 days ago (bbc.com)

I hope we create whalegemma (similar to dolphingemma) so we can explain to them how to co-exist better with humans (e.g. avoid this area during their whale hunting season, travel to this area if you get sick or tangled in rope).

> Bursting from their enormous lungs at over 300mph (483km/h), a humpback whale's blow can rise up to 7m (23ft) into the air.

Pick a lane BBC.

But this is great news. Also the fact that whales "transport huge amounts of nutrients across the globe" (linking to [1]) is fascinating. The role of whales in sucking up critters in one place and pooping them out elsewhere being a fundamental dynamic that drives global ocean ecosystems... just chefs kiss

  • It's not just the BBC, it's the UK as a whole. Miles per hour or deeply entrenched for speeds but for measurements we use meters. The same for weight, we weigh people in stone but we weigh everything else with grams.

  • I remember reading about whales returning to an area they hadn't been in for decades and people were worried about them eating all the local fish, but in fact their faeces enriched the local ecosystem from the ground up, leading to more fish. It's a bit like the counter-arguments to the lump of labour fallacy.

  • Apparently they also measurably affect the vertical water mixing. Fish need dissolved oxygen to breathe, so they don't normally venture past the thermocline. And their fins are also vertical, so they don't cause a lot of vertical water movement.

    But whales routinely dive deep, and their tail fin is _horizontal_ and it creates powerful updrafts.

    Another organism that affects mixing is apparently jellyfish.

They may gather up for a protest. See the whale north of Germany who seems unable to swim away.
