Humans love to take liberties when we talk about our heights. But Afruca tangeri fiddler crabs don’t have that luxury. Looking and listening in on the members of this species as they tried to attract mates, a team of researchers found that the males’ mating songs are shaped by their size, and are thus accurate signals of their fitness as mates, according to a press release, at least from the perspective of female fiddler crabs.Publishing their findings in a study in the Journal of Experimental Biology, the researchers say that their results reveal what information male fiddler crabs share in their songs, as well as how well they share it.Conveying Size Through SongScuttling around the noisy seashores of the Southern Iberian Peninsula, A. tangeri males court A. tangeri females through songs of seismic vibrations, by drumming or hitting the sand with their oversized claws or shells. But little is known about what, exactly, these seismic vibrations convey and how effectively they convey it next to the noisy sea. Setting out to learn more, a team of researchers from the University of Oxford’s Animal Vibration Lab recorded male fiddler crabs as they produced their seismic signals. Using GoPro cameras and geophones, which measured the percussive vibrations that the crabs produced in the sand, the team revealed that the seismic signals differed depending on whether the males drummed the sand with their claws or hit the sand with their shells. Much more intriguingly, the researchers also found that the seismic songs differed depending on the males’ morphology, allowing the females to accurately size up the males from far away.“It appears as though the males cannot, or do not, lie about their physical size,” said Tom Mulder, a study author and a biologist at the Animal Vibration Lab, according to the release. “Females can rely on the loudness of seismic signals to honestly assess a potential mate’s quality, all without needing to see him.”Read More: Understanding How Whales CommunicateThe Complicated Steps of Fiddler Crab CourtshipThroughout their study, the researchers’ GoPros and geophones allowed them to record the complicated steps of fiddler crab courtship. First, the males waved their oversized claws in the air. Second, they alternated between drumming the sand and hitting the sand with their claws and shells. Third, they performed both behaviors simultaneously. And fourth, they scrambled into their burrows and drummed the sand there, if and only if a female seemed interested. Recording vibrations for over 8,000 of these fiddler flirtations in total, the researchers found that the length, the loudness, and the rhythm of the crabs’ seismic signals differed depending on the crabs’ behavior — whether the crabs were drumming with their claws or hitting with their shells, for instance — allowing their behaviors to be differentiated based on their vibrations alone.Also shaping the males’ songs were their morphologies, with larger and smaller claws producing higher-energy and lower-energy seismic signals, respectively. “Larger claws have the advantage of overcoming seismic noise so that they can signal to females that are further away,” said Beth Mortimer, another study author and a biologist at the Animal Vibration Lab, according to the release. “However, the advantages are only observed for the percussive signals such as drumming and fortunately for smaller clawed crabs, these are only part of the courtship routine.”According to the team, the percussive signals of these crabs are advantageous for males, allowing them to attract females next to the sounds of the sea. But they’re also beneficial for females, too, making sure that the males they meet actually measure up.

Credit: ESA Get the Popular Science daily newsletter💡 A black hole is a terrifying concept, but the mysterious nexus of physics and space-time isn’t always gobbling up matter. While famous for devouring anything and everything in its gravitational pull, black holes aren’t constantly destructive. In fact, they often exhibit long periods of dormancy. Astronomers had never witnessed a black hole “wake up” in real time—until now. Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth. And what they’ve documented challenges prevailing theories about black hole lifecycles. The groundbreaking observations are detailed in a study published on April 11 in Nature Astronomy.  For decades, the supermassive black hole anchoring a galaxy known as SDSS1335+0728 in the Virgo constellation hasn’t displayed much activity. But beginning in late 2019, astronomers noticed it began to emit intermittent, bright flashes of energy. They soon reclassified the galaxy’s center as an active galactic nucleus nicknamed “Ansky,” and enlisted telescopes from NASA and the ESA to help study the unexpected event. An artist’s impression of a stellar-mass black hole similar to the one inside Ansky. Credit: European Space Agency, NASA and Felix Mirabel (the French Atomic Energy Commission & the Institute for Astronomy and Space Physics/Conicet of Argentina) European Space Agency, NASA and Felix Mirabel (the French Atomic Energy Commission & the Institute for Astronomy and Space Physics/Conicet of Argentina) “When we first saw Ansky light up in optical images, we triggered follow-up observations using NASA’s Swift X-ray space telescope, and we checked archived data from the eROSITA X-ray telescope, but at the time we didn’t see any evidence of X-ray emissions,” Paula Sánchez Sáez, a researcher at the European Southern Observatory in Germany and lead researcher of the first team to study Ansky, said in a statement. Fast forward to February 2024 when Lorena Hernández-García at Chile’s Valparaiso University began detecting even more regular X-ray bursts from Ansky. The rare events allowed astronomers to once again aim their tools like the XMM-Newton X-ray space telescope and NASA’s Chandra, NICER, and Swift telescopes at Ansky. Hernández-García and collaborators then determined the black hole was displaying a phenomenon known as a quasiperiodic eruption, or QPE.   “QPEs are short-lived flaring events. And this is the first time we have observed such an event in a black hole that seems to be waking up,” said Hernández-García. XMM-Newton proved particularly critical to studying Ansky’s behavior, since it is the only telescope sensitive enough to capture fainter background X-ray light amid the black hole’s stronger X-ray bursts. By comparing the two phases, astronomers could calculate the amount of energy released by Ansky during its more active periods. ESA’s Laser Interferometer Space Antenna (LISA) mission is the first space-based observatory dedicated to detecting ripples in the fabric of spacetime. Credit: ESA  While a black hole inevitably destroys everything it captures, objects behave differently during their impending demise. A star, for example, generally stretches apart into a bright, hot, fast-spinning disc known as an accretion disc. Most astronomers have theorized that black holes generate QPEs when a comparatively small object like a star or even a smaller black hole collides with an accretion disc. In the case of Ansky, however, there isn’t any evidence linking it to the death of a star. “The bursts of X-rays from Ansky are ten times longer and ten times more luminous than what we see from a typical QPE,” said MIT PhD student and study co-author Joheen Chakraborty. “Each of these eruptions is releasing a hundred times more energy than we have seen elsewhere. Ansky’s eruptions also show the longest cadence ever observed, of about 4.5 days.” Astronomers must now consider other explanations for Ansky’s remarkable behavior. One theory posits that the accretion disc could come from nearby galactic gas pulled in by the black hole instead of a star. If true, then the X-rays may originate from high energy shocks to the disc caused by a small cosmic object repeatedly passing through and disrupting orbital matter. As it stands, astronomers possess more QPE models than data from actual events. Thanks to Ansky’s reawakening, that may soon change. “We don’t yet understand what causes them,” said Hernández-García. “Studying Ansky will help us to better understand black holes and how they evolve.”
