This is something I have been thinking about since answering this question about guessing the size of a shark. What precautions would a scuba diver take or is this something that is simply avoided?
This question is easy! Just dive as you would. If you see a shark, don't dive towards it, because it could think you want to attack. Just stay in one spot, watch the shark, and enjoy!
Sharks are very curious animals, which just want to have a look, and then swim away. The is no need to worry the shark would attack you. Sharks are friendly and don't eat humans.
I dove a bunch of times with different sharks. I even spend 2 Years living on the fidschi islands and doing research about sharks. I saw many sharks of different kinds. Be ready to be mind-blown by these amazing creatures!
Have fun and a great dive!
