I had no idea this was how they were born.
this looks like it is in a lab. I think in the wild the clusters are huge and the mother hovers over that cluster like a tent until they hatch and then she dies. I am not sure if that is particular to one type of octopus
I don't think it's a lab but I do know it's at the Virginia Aquarium and Marine Science Center.
Wow! Talk about alien-looking. It's cool how they immediately obtain color upon emerging.
