I'd come in at the end of a whole drama.

You think, "What on earth is this animal doing?"

And I think she was a little bit afraid of me,

so she lifted this incredibly slippery...

piece of algae that you can hardly hold with your hands

and just wrapped it in this extraordinary cloak around her

and then stared at me out of the little gap.

And then, boom, you know, she was gone.

It's a hard thing to explain,

but sometimes you just get a feeling,

and you know

there's-- there's something to this creature that's very unusual.

There's something to learn here.

There's something special about her.

And then I had this crazy idea.

What happens if I just went every day?

What happens if I... I never missed a day?

And, initially, she was clearly being affected by my presence,

so I thought, "I'll leave the camera there,

and then that will record her going about her business."
