“Correct, it’s only common sense.”
About 10 years ago I got the chance to scuba-dive on the Great Barrier Reef. I’m glad nothing happened as I was a bit naive. (Rent the gear off the boat, no training, etc.)
I must say though it was one of the few things that I have done that was truly amazing and lived up to the hype - it was just like you see in the travel films. Giant clams (the 6’ big variety) and even a large (8-foot?) shark that I tried to swim closer to but it ignored me as it swam away. (Thank goodness)
I did some diving in my young days off So CA. Some of the areas were very beautiful and I’ve seen sharks but none that were real large, of course even 4 or 5 footers can do much damage.
I guess the main difference here is the chumming of the sharks, they are in a feeding mood.
