I’m coming back! How safe is the ocean for swimming?

We swim in the bay most days.
Yes, there are occasional jelly fish, usually we don't see them, just get stung. If it is a bad one, we get out and skip a day.
Haven't seen any sharks in the bay.
A couple of times a year we pass on our swim when there is a croc passing by.
It's all wonderful!

But Rob recently posted those crocs won't bother you. Is he wrong?

Those cocodrilos have been here since long before the first hotel ever opened, long before the first planeload of suntan lotion slathered margarita slurping tourists ever went for their first swim. Hundreds and sometimes thousands of people a day swim in our bay, yet during all that time not once has a cocodrilo bitten, much less eaten, anyone.
