Sometimes before we fall asleep, it makes us happy to think of all the wonderful things right under our noses that humans are just now discovering. Like mice roaring to their lovers and giraffes humming into the darkness. All kinds of “silent” animals turn out to be making a racket—we just didn’t know about it until recently. While they’re probably not going to form a new rock band any time soon, we think it’d be pretty killer if some of our favorite secret singers teamed up.
Strumming the bass: giraffes
Thought since forever to be silent giants, in 2015 researchers recorded giraffes humming tunes at night. They’re not sure yet why they hum, but it sounds like happy Tibetan monks wandering a country road.
Keeping the beat: baby fish
Grey snapper larvae pop and growl at each other in their little fishy nests. Those who watch them don’t think they’re mad; instead they might be checking in on each other in the dark when they can’t see.
At the mic: mice
Male Peromyscus sp. are more of the John Lenonesque crooners of the mouse world, while females play the Yoko, barking and roaring to their loves. All this mousy singing takes place in ultrasound, just outside our human hearing.
Adding whimsy: turtles
South American river turtles (Podocnemis expansa) would play the kazoo in our band because, to be polite, their vocalizations sound a bit like tooting. These turtles have a lot to say to each other, but our favorite is […]
Most entomologists have received a phone call along the lines of, “YOU WON’T BELIEVE THIS CRAZY BUG.” These calls often feature the same few species, and entomologists usually can make a quick tentative ID of the “usual suspects.” Here are some of eastern North America’s repeat offenders:
Unlike their periodical cousins, adult dog day cicadas turn up each summer. Males sing to females using membranes called tymbals.1 The resulting sound, resembling a shaking metal sheet, is produced when the males flex their muscles, buckling the tymbals.
This spider has been wrongly accused! The golden garden spider is often found on the sides of homes. Females are large and vibrant, while males are small and drably colored.2 The female’s bold, aposematic coloring may be frightening, but she’s unlikely to bite. If found inside, try gently moving her outdoors to safety.3
These voracious predators are aquatic and often become disoriented by porch lights as they’re flying to new habitats. To move this bug to safety, use a safe transport technique3; this species (and its close relatives) can deliver a painful defensive bite when stressed.4
House centipedes are native to the Mediterranean but have spread globally with humans.5, 6 They have 30 legs (one pair per body segment) and often turn up in basements, where they prey on smaller invertebrates.7
At Buzz Hoot Roar, we’re always telling you about what researchers are doing. This year, we let the researchers speak for themselves. At this spring’s Entomological Society of America’s SEB meeting, researchers made their own sciart about their work and wrote about it in classic BHR (brief!) style. Read on for four of our favorites.

Let the witticisms begin!
Spider mating is like two serial killers making out. Sure, they’d like to hook up, but each one is also likely to kill the other. Because male and female spiders both walk around with venom-packed fangs and a penchant for the arthropod buffet, many species have come up with some cool behaviors to form a truce and get busy.
The Hopeless Romantic
To let their girlfriends know they’re available for love and not supper, male Argiope writing spiders strum out a love song on the females’ webs. Responsive females invite their boyfriends in for “coffee” and they go at it. But male writing spiders aren’t taking any chances with paternity.
Once they mate, they die with their sex organs still clinging inside the female, using their whole bodies as mating plugs that remain there until someone eats them or they fall out.
To let females know they’re into them, Grass spiders, Agelenopsis aperta, flex females’ webs and then sway their abdomens from side to side in a hypnotic spider-love dance. Once females seem down to party, males release “spider roofies,” an airborne chemical that makes females pass out cold.
The Emotional Abuser
When they’re ready to roll, black widow (Latrodectus) females release a “come and get me” pheromone that draws males from all around. To reduce competition, an early arriving male quickly wraps up some of his potential girlfriend’s web, decreasing her pheromones’ attractiveness to other males.
Spotted orb weaver (Neoscona crucifera) males find a good thing and take no chances. If one finds a web with an immature female living in it, he’ll […]
If swimming against the flow was a fish-world Olympic event, climbing gigantic waterfalls would be an X-treme sport.
In tropical island rivers, it’s feast or famine. Yearly rainfall fluctuates between gushing flash floods and desolate patchy pools. You might think such extreme conditions too inhospitable for fish.
Not for the thrill-seeking amphidromous fish! Their adventures start upstream, where adult amphidromous organisms live and reproduce.
On their upriver journey to reproduce, fish often encounter impassable migration barriers, like waterfalls. However, for amphidromous gobies of the subfamily Sicydiinae, waterfalls are simply a conquerable challenge.
Whereas most fish have a pair of pelvic fins on their underside used for steering and stabilization, gobies (Gobiidae) have a single fused pelvic fin that holds onto rocks, like a suction cup, in turbulent waters. Sicydiinae gobies uniquely use their sucker fins in tandem with their mouths to slowly and methodically climb the faces of massive waterfalls.
Written by Patrick Cooney, a certified fisheries scientist who is unable to climb gigantic waterfalls. However, he is a leading expert in sampling and researching waterfall-climbing gobies in Puerto Rico and Hawaii. For his day job, Patrick trains fisheries scientists how to use electricity in water to safely sample fish for scientific purposes, and for fun, he co-founded The Fisheries Blog in 2012 with the purpose of sharing awesomeness about fish. Patrick is known to media agencies as the guy who spoils […]
We spend a lot of time and money on antibacterial products. But despite our desperate scrubbing, we will never be free of microbes.
In fact, our bodies’ microbial cells outnumber our human cells 10 to one! Which makes you wonder: If you have more microbial cells than human cells, are you human?
Of course! Humans play host to microscopic microbes, collectively known as the gut microbiome, that reside in the small and large intestine.
These microbial symbionts perform vital functions, especially during digestion.
Many of these genes encode enzymes that digest food, such as CAZymes, which break carbohydrates into compounds that the body can absorb or excrete.
If the composition of the gut microbiome changes, the body may lose the ability to perform certain functions, which could result in inflammatory bowel disease (IBD).
Even from the deep regions of our intestines, our gut occupants can influence much more than our bowel health.
Studies report colonization of certain species of bacteria is more likely to be associated with depression and anxiety. Many researchers believe adjusting the composition of the gut microbiome may be a viable treatment for these disorders.
We may be human, but we are run by microbes, no matter how many times we wash our hands.

We at Buzz Hoot Roar are pleased and proud to announce our newest Artist in Residence! Over the next year, Christin Hardy will use her unique graphic style to explore six science posts. Read on to learn more about Christin, and stay tuned to enjoy her excellent work.
Who: I’m Christin Hardy, a graphic designer and illustrator living in the city of oaks, Raleigh N.C., and hailing from Seven Springs, a teeny tiny town in rural Eastern North Carolina where the livestock outnumber people.
I graduated from NC State University with my bachelor’s in graphic design, and after a few odd jobs landed my current job as a graphic designer for the NC Department of Transportation. There, I get to work on projects from all sorts of divisions ranging from aviation and rail to highways and bike/pedestrian. One of my favorite projects was the poster I made for National Train Day in 2014:
Why: I’ve always loved science and tend to choose extracurricular activities that reflect that, such as volunteering for the Duke Lemur Center (so much fun), working for the entomology lab at NCSU where I counted bee sperm for a summer (not as fun, but cool) and interning at the Smithsonian in Washington D.C. (definitely ties with the lemurs).
So, when I got the email asking if I wanted to be the next artist in residence, I immediately gasped and said “YES!! Of course!!!” While I enjoy my work for the government, Buzz Hoot Roar gives me an outlet where I can […]
