Whilst on holiday one year in Tobago, Roy and our Daughter Sue who was 12 at the time were both trained to go scuba diving by 3 Canadian Fire Men who also had to dive as part of their jobs, looking for dead bodies etc when people went missing.
Once they had been trained (exceptionally well) they went off one day with all the firemen (approx 20) and two of the local divers to show them where a Nurse shark lived in a cave. Roy and Sue stayed well away from the underwater cave and watched from a distance with 2 of the divers, I was up in the boat watching the bubbles.
One of the local divers went to the cave and pulled the shark out by the tail (something he had done for 2-3 years without any problem) a Canadian diver who was the most enthusiastic was right behind him with the camera, the shark turned and came at them very quickly so much so that the Local Diver did a somersault under the water, the Canadian with the camera got pictures of the sharks eye, fins, belly and tail as it went over him and the next thing I saw was the same diver enter the boat without touching the sides, he flew through the air!!!
We discovered afterwards that the nurse shark had a baby and was obviously being very protective.
The photos from the Canadian diver were very good and very close!!!! but the best photos were the ones my daughter took from a safe distance away.
We always remember this holiday and the lovely people we met and it is a lovely place to dive (or so I am told!)
