Yassssssssss sharks are older than trees. I’m also pretty into ocean life as well

I was also really into orca whales in Jr High. There’s some pods with only a few members living next to pods with dozens and they’re separated by culture or the very few members of one pod of orcas that strategically beach themselves to catch seals. That behavior is taught to younger orcas and not all those who try stick with it and continue to practice / actually hunt that way. it’s beautiful to watch

this kinda goes into how they teach each other.

And gah!!!!!! Ask your friend’s son if he knows why there’s more fossil evidence of octopuses than of squid…. It’s because squid have higher levels of uric acid in their body to help them be buoyant, whereas octopuses “walk” along the sea floor. So if conditions weren’t just right the bodies of squid break down faster than octopuses bodies do so a smaller window to even have conditions to create a fossil never mind that the fossil could be destroyed during any of the millions of years between then and now.

I’m autistic so I’ve been a ravenous information sponge for so many different topics
