Necropsy
Write a story about a veterinary pathologist who performs autopsies on zoo animals. Each animal's death tells a story about captivity, care, and the compromises of conservation. The pathologist narrates with professional precision and a tenderness she would deny. Five animals, five deaths, one working day.

Five Findings
I.
The first was the red panda, and I will say at the outset that I had been expecting her.
Her name—though I try not to learn the names—was Suki. The keepers had found her curled in the wooden nest box at the rear of her enclosure shortly after seven that morning, forepaws tucked beneath her chin in a posture so precisely imitative of sleep that the junior keeper, a young woman called Patel, had apparently stood watching for some minutes before she understood what she was looking at. I know this because Patel told me so herself when she brought the body down to the necropsy suite at half past eight, carrying Suki in her arms like a child carrying a stuffed animal won at a fair, and I could see from the redness around her eyes that she had been crying and was trying very hard to stop.
I thanked her. I asked her to place the animal on the steel table. I did not say anything else, because in my experience there is nothing useful to say at such moments, and the things people do say—that the animal is at peace, that she lived a good life, that these things happen—are not only unhelpful but subtly cruel, since they ask the grieving person to perform agreement with a platitude when what they want is simply to be left alone with the blunt fact of the loss.
Suki weighed four point two kilograms. She was nine years old. Her fur was that extraordinary colour, the deep russet that verges on mahogany, which no photograph of a red panda has ever quite captured and which I suspect no photograph ever will. She had been at the zoo for six years, transferred from a breeding programme in the Netherlands where she had produced two litters, and she had not bred since her arrival. This was, I understood, a source of some institutional disappointment.
I made the first incision at nine fifteen. I am precise about times because the report demands it, but also because the structuring of a working day around timestamps has become, over fifteen years, a kind of discipline that keeps the work from becoming what certain colleagues in my field have admitted it can become, which is unbearable. I do not find it unbearable. I find it necessary and often interesting and occasionally, in a way I would not care to explain to anyone who does not already understand, beautiful. But I have found that the timestamps help.
There is a widespread misconception that pathology is a discipline of answers, that we open a body and discover, like a detective in a mystery novel, the single decisive clue. It is, more often, a discipline of accumulations. One observes the liver and notes its colour and texture. One weighs the heart. One examines the intestinal mucosa for lesions and the lungs for consolidation and the kidneys for the subtle mottling that indicates chronic disease. Each observation is a small, provisional statement, and it is only when they are gathered together and considered as a whole that a narrative begins to emerge, and even then the narrative is often tentative, qualified, hedged with the language of probability rather than certainty. In human medicine this tentativeness can be a source of frustration to the families of the deceased. In zoo pathology there are no families, only keepers and curators and occasionally a member of the board, and their frustration, when it comes, tends to be of a more institutional character.
Suki's narrative was not difficult to read. The liver was enlarged and pale, the texture friable, crumbling slightly under the blade. The kidneys showed cortical atrophy. The heart was within normal limits but the pericardial sac contained a small excess of straw-coloured fluid. I took samples for histology, though I was already fairly certain of what I would find: a systemic process, almost certainly hepatic in origin, progressing over months. She had been declining for some time. The keepers' notes, which I had reviewed that morning, recorded a gradual reduction in appetite, intermittent lethargy, a reluctance to climb. All of this had been attributed, not unreasonably, to the cold snap in January, to her age, to what one note rather poetically described as "seasonal low mood." Red pandas in British zoos do get quieter in winter. Many animals do. The question of when quietness tips into illness is one that even the most attentive keeper can struggle to answer, because the animal cannot say, and because the baseline for a captive animal's behaviour is already so profoundly altered from what it would be in the wild that the very concept of normal becomes, if one thinks about it too carefully, something close to meaningless.
I recorded my preliminary findings. Probable hepatic lipidosis with secondary renal compromise. In plain language: her liver had been slowly filling with fat, and the fat had been slowly killing her. It is a condition we see with some regularity in captive red pandas, and indeed in many captive species, because the metabolic demands of life in a zoo are so different from the metabolic demands of life in the cloud forests of Nepal or the bamboo thickets of Sichuan that the animal's body, shaped by millennia of evolution for one set of circumstances, simply cannot adapt to another. We feed them well. We feed them, in fact, too well, and with the wrong things, or the right things in the wrong proportions, because despite decades of research into the nutritional requirements of exotic species, we are still, in many cases, guessing.
I do not say this to indict anyone. The keepers at this zoo are dedicated and knowledgeable and they care about these animals with an intensity that I, who see only the dead, can only infer from the careful handwriting in the daily logs and the occasional tremor in a voice over the telephone. I say it because it is the truth, and because the truth, in pathology, is the only thing one has to offer.
I covered Suki with a clean drape and moved on.
II.
The second was a Humboldt penguin, male, aged fourteen, known to the keepers as Captain. I learned his name because it was written in black marker on the bag in which he arrived.
Penguins are not animals that lend themselves easily to sentimentality, despite the best efforts of documentary filmmakers. They are loud, belligerent, profoundly malodorous, and their eyes, set on either side of a narrow head, give them an expression of permanent, affronted surprise, as though the world has just done something inexcusable and they are waiting for an apology. I have always rather liked them.
Captain had been found that morning at the bottom of the pool in the penguin enclosure, which was a concrete basin painted blue to suggest the ocean. The cause of death, I expected, would be drowning, and the question would be what had precipitated it—a seizure, perhaps, or a cardiac event, or simply the accumulated fatigue of a body that had been swimming in circles for fourteen years in a pool approximately one ten-thousandth the size of the range a wild Humboldt penguin might cover in a single day.
It is worth pausing here to consider what we mean when we speak of an animal's range, because it is a concept that conservation biology has made much of, and rightly so, but which carries implications that the zoo industry has been slow to confront. A wild Humboldt penguin does not simply occupy a certain area of ocean; it moves through that area with purpose and variety, diving to depths of thirty or forty metres, pursuing fish through kelp forests and along rocky coastlines, navigating by means we still do not fully understand across hundreds of kilometres of open water. The pool at our zoo is one point eight metres deep at its deepest point. The penguin colony consists of eleven individuals—ten, now—who share this space year-round, and who have developed, as any group of social animals confined together will develop, a complex and occasionally vicious hierarchy of dominance and submission that bears approximately the same relationship to wild penguin social behaviour as a prison yard bears to a village.
I opened Captain's body and found what I had suspected. The lungs were heavy and waterlogged, the trachea full of fluid. He had drowned. But the stomach told a different story, or rather a supplementary one: it was virtually empty, containing only a small quantity of mucus and a single fish scale. His keel—the breastbone—was sharp and prominent, the pectoral muscles wasted. He had not been eating, or had not been able to eat, for some time.
In a colony of penguins, as in many social groups, access to food is determined by rank. The keepers scatter fish into the pool and the dominant birds eat first, eat most, and eat best, while the subordinate birds wait and take what is left, if anything is left. The keepers are aware of this dynamic and make efforts to distribute food more equitably, but a keeper can scatter fish and a dominant penguin can intercept them, and there is a limit to what human intervention can achieve in a social structure that the animals themselves enforce with considerable vigour. Captain, it appeared, had fallen to the bottom of the hierarchy, and the bottom of the hierarchy, in a space from which there is no emigration, is a place of slow starvation.
I noted the emaciation, the empty gastrointestinal tract, the drowning. I took samples. I wrote it up.
There is a term used in zoo management—"social compatibility"—which refers to the ongoing assessment of whether the individuals in a group exhibit behaviours consistent with acceptable welfare outcomes. It is a term I encounter frequently in institutional reports, and each time I encounter it I am struck by how much work those two words are being asked to do, and how much suffering they are being asked to contain.
III.
The third was a corn snake, and I will confess that corn snakes do not move me in the way that mammals and birds do, though I am aware that this is a failing of empathy rather than a rational assessment of the animal's capacity for suffering. We are, all of us, prisoners of our own neurology in this respect. The mammalian brain responds to mammalian cues—the large eyes, the fur, the perceived expressiveness of the face—and finds it far easier to extend concern to a red panda than to a reptile whose face, objectively speaking, has not changed expression since the Cretaceous. This is a bias I try to correct for in my work, with imperfect success.
The corn snake was female, approximately eight years old, and had been found dead in her vivarium that morning by the reptile keeper. She was one of the education animals, which is to say she was regularly handled by staff and presented to school groups and visiting children, who were encouraged to touch her and who generally did so with a mixture of terror and delight that I remember experiencing myself as a child, though I cannot now recall whether the animal in question was a corn snake specifically or some other species of manageable constrictor.
Education animals occupy a peculiar position in the zoo's moral economy. They are, in a sense, the zoo's ambassadors, presented to the public as evidence that these creatures are not to be feared, that they are worthy of interest and even affection, that the natural world is full of marvels deserving of our protection. It is a role that asks a great deal of the animal, who must tolerate being removed from her enclosure, transported in a cloth bag, placed on a table in a fluorescent-lit classroom, and handled by dozens of small, warm, damp hands, all of this multiple times per week, because the zoo's education programme is a key component of its charitable mission and the charitable mission is what justifies, or is meant to justify, the entire enterprise of keeping wild animals in enclosures in the English Midlands.
The necropsy was straightforward. Corn snakes are anatomically simple compared to mammals, their organs arranged in a neat linear sequence that makes examination relatively quick. I found a large granuloma in the lung—a single, encapsulated mass of inflammatory tissue that had been growing, by the look of it, for months. Respiratory disease is common in captive snakes and is usually attributable to husbandry problems: incorrect humidity, inadequate ventilation, substrate that harbours bacteria or fungal spores. I took swabs for culture.
What struck me, and what I recorded not in the official report but in the margin of my own notes, was the condition of the skin. Corn snakes shed their skin in a single piece, or they should; in a healthy animal the old skin peels away cleanly, like a glove being turned inside out, and the new skin beneath is bright and glossy. This snake's skin showed evidence of multiple incomplete sheds, layers of old skin adhering in patches, particularly around the eyes—the spectacle, as it is called, the transparent scale that covers the eye in lieu of an eyelid—where retained shed had built up into an opaque crust. She had been, for some time, partially blind.
An education animal, partially blind, handled several times a week, unable to see the hands reaching for her. I noted the finding. I moved on.
IV.
The fourth was the one I had been dreading, though dread is not the right word, and I would not use it in any official context. Apprehension, perhaps. Professional concern regarding the complexity of the case.
He was a Western lowland gorilla, male, thirty-one years old, one hundred and seventy-eight kilograms. His name was Kibali, and I did not need to be told this because I had known him, in the way that one knows an animal one has monitored and consulted on and worried about for years, since his arrival at the zoo in 2014.
Kibali had been euthanised the previous evening following a rapid deterioration in his condition. He had been under veterinary care for three weeks with symptoms that included lethargy, reduced appetite, intermittent vomiting, and what the clinical notes described, with characteristic veterinary understatement, as "behavioural changes." I knew what this meant because I had visited him twice during his illness, once to collect blood samples and once at the request of the senior veterinarian, who wanted a second opinion on whether the time had come. The behavioural changes were these: Kibali, who had been for eleven years the dominant silverback in a group of five, who had sired three offspring and managed the social dynamics of his group with a combination of physical authority and surprising diplomatic subtlety that the primate keepers often remarked upon, had begun to sit in the corner of his indoor enclosure with his back to the glass and his face to the wall, and had stopped responding to the keepers, and had stopped responding to the other gorillas, and had, in the final days, stopped responding to anything at all.
A gorilla is not a red panda. A gorilla is not a penguin. A gorilla is an animal so close to us genetically, behaviourally, and cognitively that the ethical questions surrounding its captivity are not questions that admit of easy answers, and I am aware that many thoughtful people, people whose opinions I respect, believe that the keeping of great apes in zoos is simply indefensible, full stop, regardless of the conservation arguments, regardless of the education arguments, regardless of the fact that the forests of the Congo Basin are being logged and mined and burned at a rate that makes the survival of the species in the wild a matter of genuine uncertainty. I do not know where I stand on this question. I know that I stood in front of Kibali's enclosure on a Tuesday afternoon and watched him sit with his face to the wall and knew that something in him had broken, and I know that the word "broken" is not a diagnostic term and would not appear in any report I might write, but I also know that it is the most accurate word I have.
The necropsy took most of the afternoon. Gorilla anatomy is, for obvious reasons, the most familiar territory a veterinary pathologist can encounter outside of human medicine, and there is a quality to the work that I can only describe as uncanny—the moment when one opens the thoracic cavity and sees the heart sitting in its pericardial cradle, four-chambered, muscular, so much like a human heart that the resemblance feels not like analogy but like recognition.
I found the tumour in the colon. It was large, infiltrative, and had metastasised to the liver and the mesenteric lymph nodes. Colorectal carcinoma. It is, and here is a fact that should give us pause, the leading cause of death in captive Western lowland gorillas, and it is virtually unknown in wild populations. The reasons for this disparity are not fully understood, but they are thought to relate to diet, to physical inactivity, to chronic low-grade inflammation associated with the stress of captivity—in short, to the conditions of the life we gave him, the life we designed for him, the life we maintained for thirty-one years in the sincere belief that we were doing something worthwhile.
I say "we" because I am part of this. I am not an outsider. I receive my salary from the same institution that received its income from the visitors who paid to watch Kibali sit behind glass, and my work—the meticulous documentation of how these animals die—is part of the apparatus that allows the institution to refine its practises and improve its care and make the case, to regulators and to the public and to itself, that it is doing a good and necessary thing. Whether it is doing a good and necessary thing is a question I have turned over in my mind for fifteen years, and I have not arrived at an answer, and I suspect I never will, because the question contains within it a contradiction that cannot be resolved, which is this: that the same impulse that makes us want to protect these animals—the awe, the recognition, the sense of kinship and responsibility—is the impulse that leads us to confine them, and the confinement is both the expression of our care and the source of their suffering, and there is no way to separate the one from the other.
I recorded my findings. I closed the body. I washed my hands.
V.
The fifth was a honeybee.
I should explain. The zoo maintains several observation hives as part of its invertebrate exhibit, and one of the colonies had been experiencing unusual mortality over the preceding weeks, and the entomologist—we do not have a full-time entomologist; we have a keeper with a particular interest—had collected a sample of dead bees and brought them to me in a small plastic container, the kind one might use for leftover soup, and asked if I could take a look.
It was twenty past five. The light in the necropsy suite had taken on that flat, grey quality that the fluorescent tubes produce when the daylight from the high windows fades, and I was tired in the way one is tired after a day spent inside bodies, which is a tiredness not only of the muscles and the eyes but of something less easily located, some faculty of attention or compassion that the work demands and that does not replenish as quickly as it once did.
I examined the bees under the dissecting microscope. There were perhaps thirty of them, each one about twelve millimetres long, each one a small marvel of evolutionary engineering that had been performing its functions—foraging, communicating, maintaining the thermal homeostasis of the hive—until it stopped. Under magnification I could see the fine branching of the wing venation, the segmented antennae, the compound eyes with their thousands of hexagonal facets, each one a separate lens gathering its own small portion of the world.
The abdomens of several bees were distended, and when I dissected one I found the midgut swollen and pale, packed with spores. Nosema, almost certainly—a microsporidian parasite that infects the gut lining and disrupts digestion and shortens the bee's life and has become, in recent years, one of several interacting factors in the global decline of pollinator populations. The spores would need to be confirmed by microscopy, but the gross findings were consistent.
I sat for a moment with the dissected bee under the lens. It is a strange thing to end a day that began with a red panda and passed through a gorilla with a single honeybee split open on a glass slide, but there was something in the progression that felt, if not meaningful—I am suspicious of the impulse to find meaning in the structure of a working day—then at least clarifying. Each of the five animals I had examined that day had died, in one way or another, because of the distance between what it was and the conditions in which it had been asked to live. The red panda's liver had failed under a dietary regime that bore no resemblance to the food she would have found in a Himalayan forest. The penguin had starved in a social structure compressed and distorted by confinement. The snake had gone blind in a vivarium calibrated for human convenience rather than reptilian need. The gorilla had developed a cancer that his wild counterparts almost never develop, in a body shaped by an environment that was, in every measurable parameter, wrong for him. And the bee had been parasitised in a hive that was, in the end, just another box in which we had placed a wild thing and hoped for the best.
I do not draw grand conclusions from my work. Pathology is not a discipline that rewards grand conclusions; it rewards careful observation, accurate recording, and the honest acknowledgment of what one does and does not know. But I will say this. Each of these deaths was, by the standards of zoo medicine, ordinary. None of them would make news. None of them would prompt a review or an inquiry or a change in policy. They would be filed, referenced, perhaps cited in a future paper on hepatic lipidosis in ailurids or colorectal neoplasia in great apes, and the zoo would continue, and the keepers would continue, and the visitors would continue to press their faces against the glass and feel whatever it is they feel—wonder, pity, guilt, love—and I would continue to come in each morning and put on my scrubs and pick up my scalpel and open the bodies and read the stories they contain.
There is a word I have been avoiding, and I will use it now because the day is over and the suite is empty and there is no one to hear me say it except the thirty honeybees in their plastic container and the gorilla in the cold room and the red panda under her drape. The word is grief. Not the keepers' grief, which is visible and acknowledged and which the institution supports with counselling services and compassionate leave. Not the public's grief, which flares briefly on social media when a charismatic animal dies and which dissipates, as such things do, within the news cycle. I mean the grief of the body on the table, the grief that is written in the wasted muscle and the swollen liver and the empty stomach and the clouded eye. The grief of an organism that was made for one world and forced to live in another, and that bore the translation as well as it could, for as long as it could, until it couldn't.
I do not put this in my reports. I put the weights and the measurements and the preliminary diagnoses and the sample numbers and the timestamps. I put everything that can be verified and nothing that cannot. But I carry it out of the building with me each evening, along with the smell of formalin that lingers in my hair and the particular ache in my lower back from hours spent leaning over a steel table, and I carry it home, and I carry it to sleep, and I carry it back in the morning, and I begin again.
I cleaned the instruments. I labelled the samples. I turned off the lights. The day, the five of them, was done.
