Do Loose Lips Really Sink Ships?

In the wake of whistleblower Edward Snowden’s leaks about the NSA’s PRISM surveillance program, I keep hearing people roll out the old World War Two phrase “loose lips sink ships.” How literally, I wonder, are we supposed to take that? Have intelligence leaks ever led directly to the loss of a U.S. naval vessel before?

Maybe. Over the course of our naval history, there have been security breaches. At the same time, there have been ships and boats and lives lost. Most of the time, it’s very hard to draw a straight line from an instance of the former to one of the latter. There’s often correlation, but not clear causation. In one of these cases, the lips that might have sunk the ships were attached to a congressman.

During WWII, concerns about national security were probably higher than ever before in U.S. history, and secrecy was paramount to security and the war effort. Civilians were reminded of this through the “loose lips” posters, and many soldiers serving overseas were issued pamphlets that reminded them that…

Silence means security — If violation of protective measures is serious within written communications it is disastrous in conversations. Protect your conversation as you do your letters, and be even more careful. A harmful letter can be nullified by censorship; loose talk is direct delivery to the enemy.

If you come home during war your lips must remain sealed and your written hand must be guided by self-imposed censorship. This takes guts. Have you got them or do you want your buddies and your country to pay the price for your showing off? You've faced the battle front; it’s little enough to ask you to face this "home front."

If only someone had given a copy of that to Andrew J. May. The Kentucky democrat served in the House of Representatives from 1931 to 1947 and chaired the House Military Affairs Committee during the war. During the summer of 1943, May and other House members visited sites in the Pacific Theater and received briefings on operations and intelligence. Upon his return home, May gave a press conference and shared a little too much of what he learned.

Americans didn’t have to worry about the safety of their submarines, he explained, because the Navy had found that the Japanese were setting their depth charges—a type of anti-submarine explosive—to detonate at shallow enough depths that the subs could avoid them. May’s comments were reprinted in various newspapers, including ones in Hawaii and other Pacific coastal areas where subs were operating.

Vice Admiral Charles Lockwood, commander of the U.S. submarine fleet in the Pacific, blamed May’s leak for leading to improved Japanese tactics and American casualties. “I hear Congressman May said the [Japanese] depth charges are not set deep enough,” Lockwood wrote in a letter to another officer. “He would be pleased to know [they] set 'em deeper now." Lockwood estimated that May’s “indiscretion” directly led to the loss of ten subs and 800 seamen.

Lockwood’s accusations and estimates might not be water-tight, though. The Navy’s “Enemy Anti-Submarine Measures” report, a summary of the Pacific fleet’s experience with Japanese anti-sub weapons, makes no mention of a change in depth charge deployment after May’s leak, and says that the Japanese were never able to figure out the full depth capabilities of American subs. Even if the depth charges were set lower, the Japanese still didn’t know how low they had to go before the subs couldn’t maneuver below them. The Naval History Division’s report of submarine losses in the war, meanwhile, does mention the use of depth charges in the attacks leading to the loss of ten subs, but the reports also couldn’t conclude the exact reasons for the loss of each of those subs. The events surrounding some losses were only learned years after the war from enemy reports or other second-hand information, and may not be entirely accurate or definitive.

Representative May, meanwhile, suffered no consequences for his big mouth except some bad press. He was later caught up in scandal, though, and convicted of accepting bribes and using his position to secure contracts and favors for a munitions company. He served nine months in prison and was pardoned by President Truman, but his political career was sunk.

Big Questions
Why Don't We Eat Turkey Tails?

Turkey sandwiches. Turkey soup. Roasted turkey. This year, Americans will consume roughly 245 million birds, with 46 million being prepared and presented on Thanksgiving. What we don’t eat will be repurposed into leftovers.

But there’s one part of the turkey that virtually no family will have on their table: the tail.

Despite our country’s obsession with fattening, dissecting, and searing turkeys, we almost inevitably pass up the fat-infused rear portion. According to Michael Carolan, professor of sociology and associate dean for research at the College for Liberal Arts at Colorado State University, that may have something to do with how Americans have traditionally perceived turkeys. Consumption was rare prior to World War II. When the birds were readily available, there was no demand for the tail because it had never been offered in the first place.

"Tails did and do not fit into what has become our culinary fascination with white meat," Carolan tells Mental Floss. "But also from a marketing [and] processor standpoint, if the consumer was just going to throw the tail away, or will not miss it if it was omitted, [suppliers] saw an opportunity to make additional money."

Indeed, the fact that Americans didn't have a taste for tail didn't prevent the poultry industry from moving on. Tails were being routed to Pacific Island consumers in the 1950s. Rich in protein and fat—a turkey tail is really a gland that produces oil used for grooming—suppliers were able to make use of the unwanted portion. And once consumers were exposed to it, they couldn't get enough.

“By 2007,” according to Carolan, “the average Samoan was consuming more than 44 pounds of turkey tails every year.” Perhaps not coincidentally, Samoans also have alarmingly high obesity rates of 75 percent. In an effort to stave off contributing factors, importing tails to the Islands was banned from 2007 until 2013, when it was argued that doing so violated World Trade Organization rules.

With tradition going hand-in-hand with commerce, poultry suppliers don’t really have a reason to try and change domestic consumer appetites for the tails. In preparing his research into the missing treat, Carolan says he had to search high and low before finally finding a source of tails at a Whole Foods that was about to discard them. "[You] can't expect the food to be accepted if people can't even find the piece!"

Unless the meat industry mounts a major campaign to shift American tastes, Thanksgiving will once again be filled with turkeys missing one of their juicier body parts.

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.
