The ‘Yoda Bat’ Gets an Even Cuter Name

The fruit bat formerly known as Yoda has found its forever name. Scientists christened the happy tube-nosed fruit bat in the Records of the Australian Museum.

The genus Nyctimene comprises 18 species, all of which live in Oceania and southeast Asia. They’ve got bright fur and faces, and noticeable spots on their wings. They will do just about anything for a mushy piece of fruit.

The family tree is no stranger to memorable common names, with cousins like N. draconilla, the dragon tube-nosed bat, and N. masalai, the demonic tube-nosed bat.

But wacky names aside, it would be hard to spot the dragon or the demon amid a lineup of other Nyctimene species.

“Bat species often look similar to each other,” biologist and co-author Nancy Irwin of York University said in a statement, “but differ significantly in behavior, feeding, and history.”

The newest member of the family showed its smiling little face during a field survey of Papua New Guinea in the late 1990s. Surveyors brought the bat to Irwin, who suspected it was a separate species. For its wrinkly ears and sage but goofy smile, she nicknamed the bat Yoda.

To confirm that they did, in fact, have a new species on their hands, Irwin and her colleagues combed through the scientific literature and museum collections. They examined nearly 3000 bat specimens from 18 museums.

Many years and many, many research hours later, Irwin and her colleagues can confidently say the Yoda bat is a species unto itself. But they won’t call it Yoda anymore—since, as Irwin points out, most local Papuans have never seen the Star Wars movies, and the word "Yoda" means nothing to them.

She went with Hamamas (a local word for happy) instead. Its full name is the Hamamas tube-nosed fruit bat, Nyctimene wrightae sp. nov. (new species). The species name was chosen in honor of conservationist and scientist Deb Wright, who spent two decades exploring and protecting Papua New Guinea wildlife.

“Until a species is recognized and has a name,” Irwin says, “it becomes difficult to recognize the riches of biodiversity and devise management. Fruit bats are crucial to rainforest health, pollinating and dispersing many tree species, therefore it is essential we know what is there and how we can protect it, for our own benefit.”

Big Questions
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.

10 Filling Facts About Turkeys

Don’t be fooled by their reputation for being thoughtless. These roly-poly birds have a few tricks up their wings.

1. THE BIRDS WERE NAMED AFTER THE COUNTRY.

The turkey is an American bird, so why does it share its name with a country on the other side of the world? Laziness, mostly. Turkish traders had been importing African guinea fowl to Europe for some time when North American explorers started shipping M. gallopavo back to the Old World. The American birds looked kind of like the African “turkey-cocks,” and so Europeans called them “turkeys.” Eventually, the word “turkey” came to describe M. gallopavo exclusively.

2. THEY NEARLY WENT EXTINCT.

By the early 20th century, the combination of overzealous hunting and habitat destruction had dwindled the turkey populations down to 30,000. With the help of conservationists, the turkey made a comeback. The birds are now so numerous that they’ve become a nuisance in some parts of the country.

3. THEY’VE GOT TWO STOMACHS.

Like all birds, turkeys don’t have teeth, so they’ve got to enlist some extra help to break down their food. Each swallowed mouthful goes first into a chamber called a proventriculus, which uses stomach acid to start softening the food. From there, food travels to the gizzard, where specialized muscles smash it into smaller pieces.

4. FEMALE TURKEYS DON’T GOBBLE.

Turkeys of both sexes purr, whistle, cackle, and yelp, but only the males gobble. A gobble is the male turkey’s version of a lion’s roar, announcing his presence to females and warning his rivals to stay away. To maximize the range of their calls, male turkeys often gobble from the treetops.

5. THEY SLEEP IN TREES.

Due to their deliciousness, turkeys have a lot of natural predators. As the sun goes down, the turkeys go up—into the trees. They start by flying onto a low branch, then clumsily hop their way upward, branch by branch, until they reach a safe height.

6. BOTH MALE AND FEMALE TURKEYS HAVE WATTLES.

The wattle is the red dangly bit under the turkey’s chin. The red thing on top of the beak is called a snood. Both sexes have those, too, but they’re more functional in male turkeys. Studies have shown that female turkeys prefer mates with longer snoods, which may indicate health and good genes.

7. THEY HAVE REALLY GOOD VISION.

Turkey eyes are really, really sharp. On top of that, they’ve got terrific peripheral vision. We humans can only see about 180 degrees, but given the placement of their eyes on the sides of their heads, turkeys can see 270 degrees. They’ve also got way better color vision than we do and can see ultraviolet light.

8. THEY’RE FAST ON THE GROUND, TOO.

You wouldn’t guess it by looking at them, but turkeys can really book it when they need to. We already know they’re fast in the air; on land, a running turkey can reach a speed of up to 25 mph—as fast as a charging elephant.

9. THEY’RE SMART … BUT NOT THAT SMART.

Turkeys can recognize each other by sound, and they can visualize a map of their territory. They can also plan ahead and recognize patterns. In other ways, they’re very, very simple animals. Male turkeys will attack anything that looks remotely like a threat, including their own reflections in windows and car doors.

10. IN THE EVENT OF A TURKEY ATTACK, CALL THE POLICE.

They might look silly, but a belligerent turkey is no joke. Male turkeys work very hard to impress other turkeys, and what could be more impressive than attacking a bigger animal? Turkey behavior experts advise those who find themselves in close quarters with the big birds to call the police if things get mean. Until the authorities arrive, they say, your best bet is to make yourself as big and imposing as you possibly can.
