I could have sworn that we've known this for decades. I'm sure I remember reading articles on this. Did I hallucinate that but somehow hallucinate it right?

This is the relevant part

But how this arm detects a mate, or delivers the sperm to the right location, has remained unclear.

Now scientists have found the arm is a sensory organ, similar to a tongue, that can detect the female hormone progesterone. This allows it to seek out and fertilise a mate, even if the male cannot see its sexual partner.

I also remember reading about this ages ago.

Maybe the scientists discovered a publication from 1975?

This is definitely something I learned long ago. Maybe it was speculation back when I believe I "learned" it, but I was pretty sure it was a known fact already

The Portuguese octopus leaves his arm in there and ditches the scene.
