Meet the hoodwinker, the ocean sunfish we misidentified for years – CBC.ca

Published

For years, ocean sunfish, or mola, spotted off Canada’s West Coast, were identified as Mola mola, the most abundant and widespread ocean sunfish species found in the Northern Hemisphere. 

But now, researchers are identifying a number of these fish as Mola tecta, or hoodwinker sunfish, a species previously thought only to exist in the Southern Hemisphere. They’re finding them as far north as Alaska.

The hoodwinker is the subject of a collaboration between researchers in Canada, New Zealand and California who are working to expose the sunfish that’s been hiding in plain sight, using crowd-sourced data from photographs and sightings along North America’s west coast. 

One of those photographs came from 2011, when former environmental consultant Matthew Drake investigated a small mola that had stranded near a seaplane base in Port Hardy, B.C. He and his colleagues called it a Mola mola

But researchers have now identified it as the elusive hoodwinker.

“It makes you question things you’ve seen in the past,” said Drake. “Sometimes subtleties can be the difference between one species and the next, and that’s what’s happened here.” 

Jackie Hildering, co-founder of the Marine Education and Research Society, who is overseeing the collection of sightings of hoodwinkers off the coast of B.C., said the discovery is a testament to how little we know about cold water life and the value of crowd-sourced data in discovering new species.

“The average person already is not aware that Mola mola are off our coast, let alone that we could be misidentifying an animal that big,” said Hildering.

“It’s inspiring that we still live in a time where we can find out that a fabulously odd-looking fish which [was] presumed to be just one species actually has a fabulously odd-looking cousin that’s also in our waters.”

Hoodwinker spotted in California catalyst for research

Prior to its fairly recent discovery, the hoodwinker sunfish had gone unnoticed for nearly 130 years. The oldest preserved specimen from the 19th century had been hidden behind in the Netherlands’ Naturalis Biodiversity Center’s museum storage behind an impassable giraffe.

Records of the hoodwinker sunfish in the Northern Hemisphere appeared two years after marine scientist Dr. Marianne Nyegaard published her discovery of the species in 2017, which she had first identified in the waters off New Zealand four years prior. 

“[Back then], I had done the best I could in trying to find where this species could be and everything pointed toward the temperate Southern Hemisphere,” she said.

But in February 2019, a dead ocean sunfish strongly resembling the hoodwinker poked holes in her theory, washing up in California, more than 6,500 kilometres north of what Nyegaard had thought was the edge of its habitat range.

At first, she couldn’t believe the coincidence. When genetic analysis proved that the animal was, in fact, a hoodwinker sunfish, moved online to search for evidence of other hoodwinkers that had been mistakenly identified as Mola mola in the northwest part of the Pacific.

“I was just trolling the net going, ‘Oh my God, that looks a lot like a hoodwinker. That looks like one too,'” said Nyegaard. “I would reach out to people and ask, ‘Have you got more photos?'”

Sure enough, Nyegaard found that many hoodwinkers had been misidentified along the western coast of North America, a discovery that has informed what she calls her pandemic passion project to track the little-understood species’ presence in distant waters.

“We find animals out of range all the time, so that’s not that unusual,” she said. “To me, the unusual bit is that there is more than one. It’s not just a 100-year occurrence or a freaky coincidence. They’re infrequent, but they’re not freakishly rare.”

For Nyegaard and her colleagues, quantifying how long hoodwinker sunfish have been living in or making their way toward Canadian waters is limited by the fact that historical records basically start with the beginning of social media. 

Lack of data prior to crowd-sourced science project

But a global pandemic that made travel impossible for Nyegaard set the conditions for creating a virtual network of marine researchers and advocates who are gathering sightings along North America’s west coast like Hildering. 

Prior to the Pacific Northwest Mola tecta study, Hildering said that data on ocean sunfish in B.C. was collected through incidental sightings recorded by Fisheries and Oceans Canada and through a directed survey from 2004 to 2006.

“There’s been collection, but never with the perspective of holy crap, there’s actually two species,” said Hildering. 

Now, she’s using her network as “a catalyst for more sightings, using social media to follow the clues of people who have posted about [mola] outside of what’s already out there.”

Hoodwinker sunfish generally have a flatter head shape and smaller, more rounded back ends than Mola mola. But the differences are subtle, meaning that in order to confirm sightings of hoodwinker sunfish, researchers rely on good, if not great, pictures.

When Peter and Roma Shaughnessy came across a sculling mola in Kisameet Bay last August, they collected GPS co-ordinates, video, and over 100 photos of the animal, they said, recording observations about its behaviour. 

“We wished someday we would see one, never thinking we would,” said the avid boaters and residents of the Chilcotin region of B.C., calling the encounter “a lifetime event.”

Data collection like that carried out by the Shaughnessys comes pretty close to the gold-standard for Nyegaard’s research.

“If we have a photo, say of a fin coming out of the water, we won’t say what it is. We’ll just call it a sunfish,” said Nyegaard. “To identify these animals, you need to have good pictures and often we don’t have them.”

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
