Why Do We Dive With Sharks But Not Crocodiles?

Why do we dive with sharks but not crocodiles?Eli Rosenberg:

The issue is the assumption that sharks' instincts are stronger and more basic.

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). Here is a PG video of the death roll. (There is also a video on YouTube in which a man stuck his arm into an alligator’s mouth and he death rolled. You don’t want to see what happened.)

7. Remember how the shark doesn’t want to eat you or fight you? This primordial beast will eat you and enjoy it. There is a crocodile dubbed Gustave, who has allegedly killed around 300 people. (I personally believe 300 is a hyped number and the true number might be around 100, but yikes, that’s a lot). Gustave has reportedly killed people for funsies. He’s killed them and gone back to his business. So maybe they won’t even eat 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.

This Outdoor Lantern Will Keep Mosquitoes Away—No Bug Spray Necessary

With summer comes outdoor activities, and with those activities come mosquito bites. If you're one of the unlucky people who seem to attract the insects, you may be tempted to lock yourself inside for the rest of the season. But you don't have to choose between comfort and having a cocktail on the porch, because this lamp from Thermacell ($25) keeps outdoor spaces mosquito-free without the mess of bug spray.

The device looks like an ordinary lantern you would display on a patio, but it works like bug repellent. When it's turned on, a fuel cartridge in the center provides the heat needed to activate a repellent mat on top of the lamp. Once activated, the repellent in the mat creates a 15-by-15-foot bubble of protection that repels any mosquitos nearby, making it a great option for camping trips, days by the pool, and backyard barbecues.

Unlike some other mosquito repellents, this lantern is clean, safe, and scent-free. It also provides light like a real lamp, so you can keep pests away without ruining your backyard's ambience.

The Thermacell mosquito repellent lantern is now available on Amazon. If you've already suffered your first mosquito bites of the summer, here's some insight into why that itch can be so excruciating.

Happy Canada Day! What Exactly Is Canada Day?

Happy Canada Day! On July 1, 1867, the nation was officially born when the Constitution Act joined three provinces into one country: Nova Scotia, New Brunswick, and the Canada province, which then split into Ontario and Quebec. However, Canada was not completely independent of England until 1982.

The holiday called Dominion Day was officially established in 1879, but it wasn't observed by many Canadians, who considered themselves to be British citizens. Dominion Day started to catch on when the 50th anniversary of the confederation rolled around in 1917. In 1946, a bill was put forth to rename Dominion Day, but arguments in the House of Commons over what to call the holiday stalled the bill.

The 100th anniversary of the nation's official creation in 1967 saw the growth of the spirit of Canadian patriotism, and Dominion Day celebrations really began to take off. Although quite a few Canadians already called the holiday Canada Day (or Fête du Canada), the new name wasn't formally adopted until October of 1982.

How to celebrate Canada Day

There are many ways to celebrate Canada Day. First: What's a patriotic celebration without a parade? Typically, parades are held in cities, towns, and villages all over Canada (though many of this year's event will be virtual, due to the coronavirus pandemic). The Royal Canadian Mounted Police have an established group called the RCMP Musical Ride. These 32 officers, who are rotated after three years' service, perform equestrian drills for the public throughout Canada.

Other Canada Day traditions that are gaining footholds are picnics, festivals, sporting events, and fireworks.

Many Canada Day events are planned all over the country, including Vancouver, Ottawa, Calgary, Toronto, Montreal, and Victoria (though, again, 2020 may look a bit different).

If you want to celebrate at home, why not belt out your own rendition of "O Canada"? You can find the lyrics here. And hear the French version as well.
