Oh yes! I swam with nurse sharks when I was in australia but it was very controlled as was was in an aquarium tank. There were manta rays and a big turtle in there as well :c)
It was, sharks are one of my favourite animals, I think they're wonderful! I would like to go down in cage and feed them, you can do it in South Africa I think so I'd have to save a lot of pennies. I'd also like to go on a boat trip to see salt water crocs and hippos which are more of my favourite animals.
