hah, TIL, thanks!

It’s how badass killer whales are made!

Sealab

OMG Sealab II (62m deep) was supplied by a mfing dolphin called Tuffy 🥲 the world needs more of this!

Edit: the lesson of sealab3 is that 100+m habitats are harder to build and maintain than the ISS, because the pressure difference is 10x larger.

No food in the upper atmosphere and all the way to space. I can guarantee we’d have space “whales” (overlords) if there were some kind of food up there (maybe just frozen spiders and bacteria). If life can adapt to pressures of 500atm, it can adapt to 0atm, gradually…if there’d be a food chain there to support it…but lower densities and/or residence times make minerals hard to come by…

Hah…maybe kessler syndrome will give the biosphere a way to reach space organically with a mineral substrate :3
