Receiving an unsolicited photo of worm-infested animal poop would make anyone cringe, unless you’re a parasite expert like Katrina Lohan. When a colleague sent her a snapshot of a watery pile of feces with a fire-engine red worm inside, she was instantly intrigued.
“She sent this to me and was like, ‘I think this is a parasite, are you interested in studying river otters?’ And I was like, ‘Ooh, I think that’s a parasite too. And yes, I am,’” Lohan, a parasite ecologist who leads the Coastal Disease Ecology Laboratory at the Smithsonian Environmental Research Center (SERC), told Gizmodo.
Her colleague discovered the otter scat on a dock at the SERC campus on the Chesapeake Bay. Scientists know surprisingly little about river otters that live in tidally influenced coastal areas, but these predators play a vital role in ecosystems. Studying the parasites in their poop would offer valuable insight into their dietary habits and the health of their habitat. So, Lohan teamed up with Calli Wise, a biological research technician at SERC and first author of the new study published in the journal Frontiers in Mammal Science on Thursday, August 14.
Wise was particularly well-suited for this study, as she’d already conducted research on river otter latrines. Yes, you read that right, but wipe that image of a tiny, adorable outhouse from your mind. Otter latrines are essentially on-land congregation areas, Wise told Gizmodo. River otters don’t just relieve themselves at these hubs but also eat, play, and lounge there. These animals are nocturnal and semi-aquatic, which makes it difficult to observe them in their natural habitat, but researchers can learn a lot from the stuff they leave behind at latrines.
Wise and her colleagues hunted for latrines along roughly 7.5 miles (12 kilometers) of the shoreline of the Rhode River, a tidally influenced subestuary of the Chesapeake Bay. “You’re looking for areas of disturbance where it looks like an animal could have gone from the water to land,” Wise explained. “Actually, beyond just looking, my best sense was my nose. You can kind of smell out a latrine,” she said. Go figure.
The researchers collected scat from 18 active latrines and brought it back to the lab. In addition to observing samples under the microscope, they performed DNA analysis using metabarcoding. This DNA sequencing technique involves extracting small snippets of DNA, amplifying them, then comparing them to a database of snippets from known species. This allows researchers to identify species present in complex biological samples.
“This method has never been used on scat left at latrines in general, for diet or parasites,” Wise said. She and her colleagues found DNA from a wide variety of parasites spanning six taxonomic classes in the scat samples. Most of the species they identified infect river otters’ prey, but there were also some that infect otters themselves.
“The fact that this method provided such a level of resolution that we could not only figure out what it was they were eating, but also see the parasites in their prey, was really cool,” Lohan said. What’s more, the findings suggest that parasites play a key role in river otters’ diets. When they infect prey species, their negative impact on the host’s health may make it easier for river otters to hunt them, Lohan explained. Thus, these predators may be culling infected individuals from populations of their prey, but confirming this will require further research, she said.

![‘Project Hail Mary’ Won’t Be Coming to Streaming Any Time Soon
With all the excitement of movies to come this week thanks to CinemaCon, it was almost easy to forget that MGM provided an interesting update on one of our favorite movies of the year that’s already out: Project Hail Mary will head back to IMAX theaters this weekend for an extended theatrical run. But that extension also means one thing: you’ll have to wait to stream it at home for a good while longer. During its presentation at CinemaCon this week MGM confirmed that Phil Lord and Chris Miller’s sci-fi hit would make its return to IMAX screens for a limited-time, one-week run starting this weekend, a move that will likely inch Project Hail Mary ever closer to crossing the $600 million box office mark. But to put a finer point on the news, Miller took to Twitter yesterday to confirm specifically that the extension means you won’t be able to watch the film at home for the forseeable future.
We announced yesterday that MGM is extending the exclusive theatrical window for PROJECT HAIL MARY so it won’t be on streaming anytime soon. This is a movie that needs to be seen on a big screen – and w a full return to IMAX screens for 1 week only starting this weekend, make… https://t.co/suK8NYpgWM — Christopher Miller (@chrizmillr) April 16, 2026 “It won’t be on streaming any time soon,” Miller’s tweet reads in part. “This is a movie that needs to be seen on a big screen […] Bring friends and loved ones. It’s an experience to share with others.” Project Hail Mary launched on March 20, so it’s not too surprising that it’s not headed home just yet—it’s just shy of a month into its theatrical window, which has now been extended by at least another week with the return to IMAX. But as studios begin to try realigning towards more theatrical releases with longer exclusivity windows again (one of the lingering aftereffects of covid’s impact on movie theaters), we should probably expect some of the biggest films of the year and beyond to try and hold off of hitting streaming for as long as they can.
At least in Project Hail Mary‘s case, you can still go and see it somewhere, even if it’s not at home. Good things come to those who wait, but for now, you can head to a movie theater to get your fix again. Want more io9 news? Check out when to expect the latest Marvel, Star Wars, and Star Trek releases, what’s next for the DC Universe on film and TV, and everything you need to know about the future of Doctor Who. #Project #Hail #Mary #Wont #Coming #Streaming #TimeAmazon MGM,Project Hail Mary,Streaming ‘Project Hail Mary’ Won’t Be Coming to Streaming Any Time Soon
