I saw a program on TV about 6 months ago. It featured a lady diver (I think she was free diving), and she had a special relationship with an eel!
It would remember her and come out each time she dived down, even if she hadn't dived in the area for a couple of years. When it came out it swam and danced round her, it was a really wonderful moment to watch.
I keep telling people about it, but would love to know the name of the diver so that I can search for a clip to show people.
A shot in the dark I know!
Thanks.
