This Rare Shipworm Is Not Safe for Work

Scientists recently found a massive, suggestively shaped shipworm squelching through the mudflats of the Philippines—the first time the creature has been spotted alive. They described the “beefy, muscular” animal in the Proceedings of the National Academy of Sciences.

Shipworms are extraordinary creatures. They’re best known for making marine archaeologists' lives harder by riddling sunken ships with holes. As our planet's oceans heat up, so, too, does the rivalry between researchers and shipworms, which are moving fast into now-comfortably warm waters full of Viking ships. It's an "alarming scenario," the leaders of Denmark's Wreck Protect project note on their site.

Shipworms aren't true worms, but bivalves like mussels and clams. But where a clam’s slimy foot is relatively short, the shipworm’s just keeps going. The majority of shipworm species are “very delicate, translucent, usually white, beige or pink,” lead investigator Daniel Distel of Northeastern University in a statement. “They’re mostly small, a few centimeters long.”

And then there’s Kuphus polythalamia, which is decidedly … not delicate. People have been finding its rigid, tusk-like, 3- to 5-foot-long shells for hundreds of years, so scientists knew the giant shipworm existed. They’d just never seen one alive.

Then a Philippine television channel aired a documentary about a strange lagoon where long, stiff stalks emerged like fence posts from the mud, and local people ate the shipworm as a delicacy. A researcher sent the video to Distel and his colleagues, all of whom got pretty excited.

"For a biologist who is interested in these bivalves, it's like a unicorn," said senior author Margo Haygood of the University of Utah.

Distel, Haygood, and their team went on an expedition to the muddy lagoon, and there they found the shipworms. They rinsed off one specimen, packed it in a PVC pipe, and ferried it carefully back to the lab for closer inspection.

"When I took that thing out of the tube, there was a collective gasp among the whole group," says Distel, "along with quite a number of expletives." The shipworm was “like a baseball bat.”

The creature from the sticky lagoon is more than just an oddity. Unlike other shipworms, it doesn’t seem to eat wood—or anything else, for that matter. It’s not a matter of scarcity; the lagoon where the researchers picked their K. polythalamia was full of rotting wood. But that bounty goes untouched, and the giant shipworm’s digestive organs have withered to nearly nothing. So how does it live?

By making friends with microbes. The shipworm "consumes" hydrogen sulfide gas, a natural byproduct of wood decay, which is then processed into nutrients by the bacteria living within its enormous gills.

If it doesn't feed on the wood itself, why bother with wood at all? The researchers believe K. polythalamia is a descendent of a wood-eating ancestor, but that over time it formed this unique relationship with the bacteria it hosts. "We believe that somewhere along the line a shipworm acquired a sulfur-oxidizing bacteria as a symbiont, and it was able to get energy not just from the wood but also from the inorganic gas hydrogen sulfide coming from the wood as it rotted," Distel said. "Eventually the new symbiosis completely replaced the old symbiosis."

Now there's a way to make nice with the archaeologists.

A Nubian Goat Named Lincoln Was Just Sworn in as the Mayor of Fair Haven, Vermont

Lincoln the goat may not be housebroken, but she had no problem winning the race for mayor of Fair Haven, Vermont. The new mayor was officially sworn in on Tuesday, March 12, and before signing the oath of office with her hoof print, she marked the occasion by defecating on the town hall floor, the Boston Globe reports.

Prior to getting into politics, Lincoln the droopy-eared Nubian goat lived a simple life. A local family looking for a way to maintain the unruly vegetation on their property had purchased her two years ago when she was 1 year old. At age 3, Lincoln transitioned from munching grass full-time to running for public office.

Though Lincoln's win is impressive, her election didn't involve beating any human candidates. Town Manager Joseph Gunter came up with the idea to hold an election for honorary pet mayor of Fair Haven as way to raise money for a new playground. For a $5 fee, local kids were allowed to nominate the pet of their choice to be town mayor. Lincoln bested more than a dozen candidates, including a gerbil named Crystal and a pacifier-sucking dog named Stella, for the position.

The stunt didn't raise much money—the town came away with just $100 for the playground—but it did earn Fair Haven international attention. In order to go down in history as world's longest-serving animal mayor, Lincoln has to stick around for a while; Stubbs the cat was mayor of Talkeetna, Alaska for 20 years.

The 10 Most Popular Puppy Names of 2019

If you brought home a new dog or puppy recently and named it Luna, you’re far from the only one. The name, which means moon in Latin, is the most popular puppy name for 2019.

This analysis of cute canine monikers comes from Trupanion, a provider of medical insurance for pets. The company looked at its database of 500,000 dogs and crunched the numbers to identify the names that are currently having a moment. (Although some of the names that cracked the top 10 list, like Daisy and Max, have been around for quite some time.)

Interestingly, Luna wasn’t always popular. As Trupanion points out, “Looking back 10 years, Luna was barely a blip on the name game chart … not even cracking the list of top 20 names.” Nor did it appear on ​Banfield Pet Hospital's list of the 10 most popular dog names of 2018.

Often, there's some overlap between popular pet names and baby names. Luna was the 31st most popular baby name for girls in 2018. This is perhaps linked to the popularity of the Harry Potter character Luna Lovegood, as well as the publicity the name has received in recent years from celebrities like John Legend and Chrissy Teigen and Penélope Cruz and Javier Bardem, as both couples named their daughters Luna.

Second on the list of popular puppy names is Bella (its longer form, Isabella, was the fifth most popular baby name for girls last year). Check out the top 10 list below to see if your pooch’s name is trending right now.

1. Luna
2. Bella
3. Charlie
4. Bailey
5. Lucy
6. Cooper
7. Max
8. Daisy
9. Bear
10. Oliver
