27/07/2007: "LITTLE SEAL ROCK ...... adult female grey nurse shark"

This big shark and all the smaller grey nurse in the school resting at Little Seal Rock (NSW) were easily spooked when Jocelyn dropped in on them from above.

Details were in last month's notes. I couldn't locate this picture at the time.

Our dive illustrated how this species avoids divers - at first.

In time they would possibly settle down and accept our presence. Maybe. Some people believe grey nurse sharks get annoyed by many dive visits and move to deeper water.

People are spun the line "these sharks are almost extinct - there are less than 500 of them left".

My 16mm film taken at the time with a motor drive camera is a good record of how a grey nurse shark school avoided a single diver swimming amongst them, by bolting for deeper water.

This original footage has not been cut. It remains a good example to show how easy for just two divers to spook about 20 sharks
