There are a couple of reasons swimming with sharks is safer:
1. Most sharks do not like the way people taste. They expect their prey to taste a certain way, like fish/seal, and we do not taste like that. Sharks also do not like the sensation of eating people. Bigger sharks like great whites enjoy prey with a high fat-bone ratio like seals. Smaller sharks enjoy eating fish, which they can gobble in one bite. So, while they might bite us, they pretty quickly decide “That’s not for me” and swim away. There is only one shark that doesn’t really care about humans tasting icky: that shark is our good friend the tiger shark. He is one of the most dangerous species because of his nondiscriminatory taste (he’s called the garbage can of the sea)!
2. Sharks are not animals that enjoy a fight. Our big friend the great white enjoys ambushing seals. This sneak attack is why it sometimes mistakes people for seals or sea turtles. Sharks do not need to fight for food. The vast majority of sharks species are not territorial (some are, like the blacktip and bull). The ones that are territorial tend to be the more aggressive species that are more dangerous to dive with.
3. Sharks attacked about 81 people in 2016, according to the University of Florida. Only four were fatal. Most were surfers.
4. Meanwhile, this is the saltwater crocodile. The saltwater crocodile is not a big, fishy friend, like the shark. He is an opportunistic, aggressive, giant beast.
5. Crocodiles attack hundreds to thousands of people every single year.Depending on the species, one-third to one-half are fatal. You have a better chance of survival if you played Russian roulette.
6. The Death Roll. When a crocodile wants to kill something big, the crocodile grabs it and rolls. This drowns and disorients the victim (you).
7. Remember how the shark doesn’t want to eat you or fight you?
8. Sharks are mostly predictable. Crocodiles are completely unpredictable.
9. Are you in the water or by the edge of the water? You are fair game to a crocodile.
10. Crocodiles have been known to hang out together. The friend group that murders together eats together. Basks of crocodiles have even murdered hippopotamuses, the murder river horse. Do you think you don't look like an appetizer?
11. Wow, look at this. This blacktip swims among the beautiful coral, surrounded by crystal clear waters and staggering biodiversity. I want to swim there!
Oh wow, such mud. I can’t say I feel the urge to take a dip. (Thanks to all who pointed this out!)
12. This is not swimming with the crocodiles. More like a 3D aquarium.
