My sister has always been a huge fan of otters, so I always think of her when I see them. And I think of my Dad, because when I was in high school, I did an assignment for science on otters. We had to give a speech too and I was so nervous about that. So I decided I'd tape some background sounds to go with my talking, for a classy presentation!
So, I laid in the bathtub with the tape recorder going (this is in the olden days!) and I splashed and sloshed around in the bath. Then my Dad came in and made this "Aaarghkk, aarghkk, aarghkk" noise and left.
OMG I was wet. I couldn't stop the recording. I couldn't scream at him or the last ten minutes of sloshing was wasted. So I sucked it up and finished my otter sounds. When I asked him what on earth he was doing, he was a seal, getting ready to eat the otter. How we laughed. It was just too funny not to leave it in there. And so I went to school with a tape of water sloshing and a dad being a seal. I got a great mark for my ingenuity!!
So, on that note, I'll let you look up any sensible facts about otters if you'd like. The Taronga Zoo site has some here.
It is interesting that otters live in large family groups and that family is important to them :)
