falling in time with the slow roll of the waves We had spent the morning looking for humpback whales in Wilhelmina Bay, threading our rubber boat between gargantuan icebergs that were tall and sharp, like overturned cathedrals Now we stopped, cut the engine, and listened in the utter stillness for the lush, sonorous breath of an eighty thousand pound whale coming to the water s surface That sound would be our cue to close in We had come to the end of the Earth to place a removable tag on the back of one of these massive, oceangoing mammals, but we took nothing for granted in Antarctica As we sat waiting on the small open boat, I came to feel and vulnerable, a speck floating in a sea of shattered ice Don t fall in, my longtime collaborator and friend Ari Friedlaender deadpanned.I struggled to remember how long we had been away from the Ortelius, our much larger oceanic vessel with its ice hardened steel hull In every direction, we were enclosed by a landscape of nunataks, jagged spires of rock that pierced the creamy tops of surrounding glaciers Where the glaciers met the sea, they ended in sheer, icy cliffs towering over the bay Without a human structure for scale, these landforms seemed both near and far at the same time This otherworldly scene of ice, water, rock, and light warped my sight lines, bending my sense of distance and the passage of time.If you hold your fist with your left thumb out, your thumb is the western Antarctic Peninsula your fist, the Antarctic continent s outline The Gerlache Strait is part of a long stretch of inner passageway along the outer side of Antarctica s left thumb, and Wilhelmina Bay cuts a rough cul de sac off the Gerlache The Gerlache is a hot spot for whales, seals, penguins, and other seabirds, and Wilhelmina Bay is the bull s eye All come here to hunt for krill, small crustaceans that form the centerpiece of Antarctic ocean food webs Consider your hand again individual krill are about the length of your thumb, but whales pursue them because they explode into great aggregations, or swarms, during the Antarctic summer With the right mixture of sunlight and nutrient rich water, dense clouds of krill form a sort of superorganism that can stretch for miles and concentrate in hundreds of individuals per cubic foot By some measures, there is biomass of krill than of any other animal on the planet Calorie rich swarms of them lurked somewhere, not far, just under our boat.Where there are krill in sufficient quantities, there will be whales, but the fundamental problem with studying whales is that we almost never see them, except when they come to the surface to breathe or when we dive, in our own limited fashion, in search of them Whales are inherently enigmatic creatures because the parameters of their lives defy many of our tools to measure them they travel over spans of whole oceans, dive to depths where light does not reach, and live for human lifetimes and even longer.In Wilhelmina Bay our goal was to attach a sleek plastic tag to the back of a whale to record audio, video, depth, changes in the whale s speed, and even pitch, yaw, and roll Our tags would provide crucial context for how humpbacks interact with their environment by relaying, in a time stamped way, how they feed on krill Ari and his colleagues have tagged and tracked whales along the Antarctic Peninsula for nearly two decades, charting their movements against the backdrop of changes in krill patch density, water temperature, daylight, and other variables As climate change warms the poles faster than the rest of the planet, every year counts.I sat on the gunnel of the boat while Ari scanned from the bow We were several days into a multiweek expedition with high hopes to tag as many humpbacks as possible ideally, a pod feeding together but thus far we had been skunked Ari stood rigid like a figurehead, holding a twenty foot long carbon fiber pole in folded arms The pole flexed in synchrony with the swell, the teardrop shaped tag bobbing at one end I watched clouds shift slowly overhead, mirroring the dappled quicksilver of the water, and wondered whether any other place on Earth could feel as alien as Antarctica Then a loud gurgle interrupted my daydreaming, followed by a trumpeting blast of water vapor bursting from flaring, paired nostrils A whale s blow.We knew to expect plumes of water immediately thereafter A pod of whales synchronize when they surface to breathe sometimes nearly simultaneously or split seconds apart They usually breathe a few times in a row, in quick succession, before resubmerging unless they re asleep or truly exhausted, whales tend to act like surfacing is a nuisance and they d rather be deep underwater Their tight coordination in breathing likely has a lot to do with maximizing time spent below the surface engaged in the cooperative tasks of finding food and avoiding predators Some species travel or hunt in pods that are tightly knit family genealogies, while others, such as the humpbacks before us, form short lived associations, seemingly a matter of happenstance. Oh, that s right, Ari called out The vapor from the blow lingered in the cold air Ari pointed to a small patch of water a dozen yards from the boat, perfectly calm against the waves at the surface This patch, called a flukeprint, betrayed the whale s movement, unseen deep below our tiny boat The single flukeprint bloomed into several, each the size of our boat, rising up from the depths, whirling and spreading into the smooth geometry of a lily pad We were right He s got buddies, Ari said Without the aid of an echo sounderwhich would also tip off the whales about our locationwe used the ephemeral patterns on the surface to read their path.We started up the engine, throttling ahead slightly to a spot beyond the last flukeprint Within seconds, right on cue, a pair of enormous nostrils bubbled at the surface, releasing a thundering tone and then a spray that carried past us as we kept up with the whale A dorsal fin surfaced, and a second and third blow exploded nearby Pull up behind this last one We have about three breaths until they go down, Ari shouted.We trailed the laggard of the group, maneuvering the boat into position Ari lowered himself across the bow and held the pole against his torso, extending the tip with the tag just ahead of the dorsal fin as we motored close to the behemoths moving yards away Then, in a decisive motion, Ari launched the tip of the pole toward the whale s back, where the tag s suction cups hit the skin with a satisfying thwack The whale rolled beneath the surface as we pulled back to pause and wait for it to return We spotted its sleek, shiny back as it arose again, marked with a neon tag, and we cheered The whale took one last breath before it raised its monstrously wide tail flukes out of the water and slipped down into emerald darkness with the others Ari radioed back to the Ortelius Taaaaag on, he said with a hint of swagger as he grinned at me.The whole rodeo of tagging is a bit like sticking a smartphone on the back of a whale, complete with the logistics of getting close enough to a forty ton mammal in the first place Just as your smartphone can record movies, track where you go, and automatically rotate images, the same technologyminiaturized and cheap, combining video, GPS, and accelerometers all in one devicehas fueled a revolution in understanding how animals move throughout their world Scientists call this new way of recording organismal movement biologging, and it has captured the interest of ecologists, behavioral biologists, and anatomists, all interested in knowing the details of how animals move through space and over time Biologging has been especially important for revealing the daily, monthly, and even annual meanderings of animals that are extremely difficult to study Stick a tag on a penguin, a sea turtle, or a whale, and there s a chance to know how it swims, what it eats, and everything else it does whenever you re not around to watch it which is most of the time, for animals at sea.The logistics of studying whales places them in a realm truly apart from every other large mammal on land or at sea To know anything about them in the wild takes time on a boat, sticking a tag on their back, sliding a camera underwater, or spying overhead with a droneif you re lucky enough to come upon them in the first place Biologging is helping us overcome this challenge by giving us a remote view into their lives, an extension of our senses intimate and sometimes detailed than any telephoto lens In the case of humpbacks, tag data have revealed how these gulp feeding whales lunge at large schools of krill and other prey, oftentimes in coordinated attacks It s a form of pack hunting, which might seem strange for a species celebrated as gentle giants But baleen whales are serious predators, not like grazing cows but like wolves or lions, pursuing their quarry with strategy and efficacy Don t be fooled by their lack of teeth, or just because krill don t bleat in terror.Hours later the Ortelius prowled silently through Wilhelmina Bay, with a pair of massive spotlights leading the way in search of icebergs in our path Outside on the bow, I watched heavy snowflakes drift through the cones of light as Ari unfolded the metal radio antenna that would lead us back to our tag The tags we were using had to be re collected to yield their data we would have to find and physically pluck them out of the water, provided that they d already been knocked off the whales backs By design, they can last minutes, hours, or even days from the force of suction alone, before being scraped, being bumped, or falling off Its buoyant neon housing would keep the whole device floating on the surface until we triangulated its position.Over the course of his career, Ari has probably tagged species of whales than anyone, in all circumstances and in every ocean Beyond friendship, mutual colleagues, shared ambitions, and wry humor, we were working together in Antarctica to build a bridge between our disciplinespaleontology for me, ecology for himbecause questions about how whales evolved to become masters of ocean ecosystems over fifty odd million years need to be grounded in the facts of what whales do today Bridging gaps between disciplines sometimes necessitates spending time side by side All the better if it s in the field.The metal prongs that Ari assembled looked like an elaborate set of rabbit ears from an old television set He plugged the antenna into a small receiver with a speaker, and after a few moments, we heard a series of intermittent beeps That gap between the beeps tells us that the whale is sleeping, rising up to the surface to breathe, and then sinking back down Ari smiled Just dozing, belly full of krill Not a bad way to spend a Saturday night We would need to come back later and listen again for our tag until it floated freely, beeping uninterrupted.Most large baleen whale species alive today belong to the rorqual family, which feed on krill and other small prey by lunging underwater They comprise the familiar members of the cetacean bestiary, including humpbacks, blue whales, fin whales, and minke whales Rorquals are also the most massive species of vertebrates ever to have evolved on the planetfar heavier than the largest dinosaurs Even the smallest rorquals, minke whales, can weigh ten tons as adults, about twice as much as an adult bull African elephant Rorquals are easy to distinguish from any other baleen whale, such as a gray whale or a bowhead whale Look for the long, corrugated throat pouch that runs from their chin to their belly button And yes, whales have belly buttons, just like you and me The features that make rorquals so obviously different from other baleen whales also play a critical role in how they feed.A palaeontological howdunnit embedded in a travelogue devoted to chasing living and extinct whales Spying on Whales captures the excitement of suction cup tagging of humpback whales, and of digs in Panama, seeking answers to deep questions in cetacean science Nature Spying on Whales represents the best of science writing The subject is inherently fascinating, the author is an authentic scientist by virtue of his personal research on the subject, and the text reads like the epic it truly is Edward O Wilson, Pulitzer Prize winner and New York Times bestselling author of The Origin of Creativityand The Meaning of Human Existence Reading Spying on Whales leaves a strong impression, based on the principles of ecology, evolution, and physiology, that a world including whales seems awesomely improbable And, of course, wonderful Nick Pyenson guides us through this world, and in the process achieves that rare state of grace for a writer of scienceproducing prose that is both scientific and beautiful This is a moving, informative, evocative book Robert Sapolsky, author of Behave Spying on Whales is a delight on many levels It s an introduction to the science of whales, but it s also the odyssey of a scientistand whether he s tracing the fossil history of whales or describing the dissection of a giant whale heart, Pyenson tells his story with warmth and wit Carl Zimmer, author of She Has Her Mother s Laugh Knowing whales means following them when they dive out of sight, tracing their evolution through desert fossils, and reading great writers as well as the unpublished journals of dozens of scientists who, little by little, chipped away at vast mysteries If that doesnt seem easy, it could explain why only one person has done it all Youre holding his fantastic book in your hands Carl Safina, author of Beyond Words What Animals Think and Feel Nick Pyenson s Spying on Whales is both a lucid deep dive into the natural history of these animals and, subtly, an artful portrait of our own species enchantment with them It s an enthralling book about everything we know and our compulsion to know it Jon Mooallem, author of Wild Ones and American Hippopotamus With captivating prose, Nick Pyenson takes us on a scientific tale as big as a blue whale Give your inner paleontologist a treat and learn what its like to study the largest animals the world has ever seen Jonathan Losos, author of Improbable Destinies There are very few creatures that so fully capture our imagination as do whales and Pyenson proves why they continue to pique scientific and popular curiosity Part science, part memoir, and all about whales, Pyensons fantastic book is a must read for any science and nature enthusiast Lydia Pyne,
