(For the analogy: the octopus dies when their kids are hatching, would they have the ability to pass their knowledge along to them, today eight armed space suits would be en Vogue)

Thank you for sending me down that rabbit hole, it was a really interesting read, and I learned something new today.

From an article on the subject…

Octopuses are serious cannibals, so a biologically programmed death spiral may be a way to keep mothers from eating their young.

They also can grow pretty much indefinitely, so eliminating hungry adults keeps the octopus ecosystem from being dominated by a few massive, cranky, octopuses.
