It takes that animal to a different level.

Oh, then she completely lost interest in the fish,

rushed over...

grabbed hold of me.

And that was the last time we had physical contact.

[thunder rumbling]

If I think back,

and I remember it was a very rough day, very turbulent.

Sediment everywhere.

Go down and whoa,

"Oh, my God, what's going on?"

And then seeing that both animals are pretty relaxed

and realizing, "Okay, and then the mating is beginning."

By this stage, I knew quite well the stages of an octopus's life.

So while I was very excited that this mating was beginning,

there was a sort of...

this dread in the bottom of my stomach.

She wasn't coming out of that den.

There was no more feeding, no more hunting.

A huge part of her body is actually given to those eggs.
