Science Fiction Story: A marine biologist studying a rare coral colony that recovers from damage faster than it should is injured during a dive. The wound is shallow, almost trivial. What follows is quiet, clinical, and increasingly wrong. The injury closes. Then it closes again. A surface, he keeps reminding himself, is only a surface.

The photograph was the best one David had taken all morning, and Alex would not let him have it.
“Your description is excellent,” Alex said from the tablet propped against the cooler. “New tissue paler than the old, polyps retracted along the margin, a clean boundary about four millimetres inside the edge of the damage. I could draw it from what you’ve told me. The image is still out of focus.”
“There was surge.”
“There’s always surge. I understand it’s a feature of the ocean.”
Susan laughed without looking up from her slate. She was sitting on the gunwale with her fins already on, copying current readings into the dive log in the small square handwriting she used for anything that mattered. Three days into the visit she had the look David remembered from years ago, before her work had moved indoors to screens full of satellite passes: sunburned across the nose and entirely content.
In the corner of the tablet, the laboratory feed showed bench four at the institute. The droid stood there under the white lights, a wheeled column with two long arms and a ring of cameras where a head would have been. Someone had once stuck a strip of blue tape across its chest and written BENCH HANDS on it, and nobody had ever taken it off. It was lowering a small tube into a rack with great care.
Kerith Bodden, the local diver their permit required, leaned in to look. “What’s it doing?”
“Waiting, mostly,” Alex said. “The sequencer has forty minutes left on a run and can’t be hurried. In the meantime I’m preparing a reference specimen for someone else’s project. Which is my point, David. I can’t put a photograph in a tube. If patch four is recovering the way you think it is, I need a core, and I need it preserved properly, and then I need about a week.”
“Patch four looked finished,” David said. “Nine days ago that was bare skeleton.”
“Looked.”
“Looked,” he agreed. That was the whole question, and the reason he had spent two years getting permission to touch this colony at all. A small population of a rare coral near the lip of the reef wall, and some of its damaged patches closing over faster than they had any right to. But a surface was only a surface. Until he had a core he could not say whether there was sound structure underneath or a skin stretched over nothing. “I’ll take the second sample Thursday. Today is measurements and a better photograph.”
“I’ll look forward to it,” Alex said. “The photograph especially.”
They went in at ten. The water was warm enough that David dived in board shorts and a thin rash vest, and at fourteen metres the reef edge was the dim blue-green that turned every colour into a version of itself. Susan hung a little above him with the current meter. He settled beside the overhang where patch four sat, braced two fingers on dead rock, and twisted to bring the camera around. The vest rode up his ribs.
Something hit him.
It was as fast as that. A blow along his left side like a rope pulled hard through a hand, a pale shape already leaving, and then nothing in the water but the overhang and his own bubbles. He had not seen it arrive. He was fairly sure he had not seen it at all, only the place where it had been.
He looked down. Along his flank a line had opened, and from it rose a string of small dark beads. At that depth the blood was not red. It was a deep bottle green, and each bead tumbled slowly as it climbed, turning over and over in no hurry, until the current took them sideways along the wall and they were gone. He watched them longer than he should have.
Susan’s hand closed on his arm. She had her thumb up, and she was not asking.
On the boat it looked like almost nothing. Kerith held the first-aid box while Susan rinsed the wound with fresh water and then saline, and David stood with his arm raised, more embarrassed than hurt. The line ran from just under his ribs back toward his hip. Susan laid the slate’s ruler along it.
“Eight inches,” she said. “It skips in three places. David, it’s barely through the skin.”
“It’s stopped bleeding.”
“I can see that.”
It stung with the antiseptic, and then it mostly didn’t. It felt like a rope burn or a graze from a rough wall. He pressed around it and found no deep soreness. Susan photographed it with the ruler in frame, then again closer, and wrote the time and the station number in the log beneath her current readings.
“If a student did this, you’d send them to a clinic,” she said.
“If a student did this I’d tell them to keep it clean and covered and watch for redness. Which is what I’m going to do.” He lowered his arm. “It’s a scrape, Sue. If it changes, I’ll go.”
She studied him for a moment, then the wound, then him again. “Photographs every morning. And you’re out of the water.”
“Agreed.”
Alex had the camera footage within the hour. “Eleven frames,” Alex said. “I can tell you with confidence that it had a tail. Beyond that I’d be guessing, and so would anyone else. Are you all right?”
“It’s shallow.”
“That wasn’t quite what I asked, but I’ll take it. I’ve redrawn the schedule. Susan and Kerith do the remaining transects and Thursday’s core. You run the surface log and label things. You’ve always said nobody labels things properly.”
“Nobody does.”
“Then this is your opportunity.”

By the fourth day a membrane had formed over the line.
It was brownish and slightly translucent, thinner than any scab he remembered, and it lay very flat. When Susan changed the dressing she turned him toward the window and looked at it for a while.
“It’s got a pattern,” she said. “Little ridges, running across it. Like corduroy.”
He craned to see. They were faint and parallel and evenly spaced, a few millimetres apart. “Teeth,” he said. “Or the weave of the gauze. It’s dried against something.”
“Probably.”
There was no redness spreading from it and no heat. He had no fever, and he took his temperature every morning because Susan stood there until he did. It did not hurt unless he pressed, and then only a little. By the signs he and Susan were watching for, it was healing well.
Two things were slightly off, and both had explanations. The skin on either side of the line stayed thin. When Susan peeled the tape away, a little of the surface came with it, the way skin does after a bad sunburn, and she switched to a paper tape that did the same. And he was tired. He spent the days on the boat tending lines, logging Susan’s and Kerith’s dives, and writing labels, and by three in the afternoon he wanted to lie down. He put it down to the heat and sleeping badly on his right side.
Thursday’s core came up clean. He labelled it himself, patch four and the date and Susan’s station number, and packed it in preservative for the journey home.
Twelve days after the bite he was in the shower at the rental, an old house with a tiled stall and a drain with wide brass slots, when he felt one end of the strip lift. He left it alone, as he had been leaving it alone for days. The water got under it. It came away along its whole length in one piece and lay across his fingers for a second, supple and wet, heavier than he expected. Then it slid off his hand, folded once against the tiles, and went down between the slots.
He looked at his side. The skin beneath was pink and smooth and whole.
He thought of patch four. A surface is only a surface. He stood with the water running and turned the thought over. Then he reminded himself that he was not a coral, that he had no fever, and that this was what the end of a scrape looked like.
“It came off,” he told Susan, and raised his arm.
She photographed the pink line with the ruler beside it. “That’s that, then,” she said, and kissed his shoulder.

It was not quite that. In the last days of the visit the pink dulled. By the time they flew home there was a faint brown film over the line again, and he blamed the strap of his dive bag and then the long flight.
At home he changed how he dressed. He wore loose shirts, stopped sleeping on that side, and put a non-stick pad over the place so that nothing would rub the new skin. Susan went back to work. He unpacked the samples and delivered them to the institute, where the droid received each container at the intake window, read the label twice, and placed it where Alex said it should go.
“Your labels are immaculate,” Alex said. “I’ve decided to say so before I find the exception.”
He meant to stay late that week and did not. Twice Susan came home to find him asleep on the sofa at six with his shoes on.
“You’re doing less than you did before we left,” she said the second time, sitting down on the arm beside him. “And you’re sleeping more.”
“Travel. I’m still on island time.”
“Island time is one hour different.”
Twenty-five days after the bite, the second strip came away while he was changing the pad in the bathroom. It was a little thicker than the first. He laid it on the blue cleaning cloth on the vanity, which was damp from wiping down the basin, and got on with taping a fresh pad over skin that once again looked pink and nearly healed. Then the phone rang in the other room, and he went to answer it with the old pad still in his hand.
Three evenings later Susan sat at the kitchen table with her laptop and every photograph they had taken since the boat, arranged by date.
“Come and look at this,” she said.
He looked. She had the first membrane on the left of the screen and the second on the right, each with the ruler in frame.
“Same ridges,” she said. “Not just ridges. The same ones. Look at the end nearest your hip.”
At the hip end of each strip, two ridges sat closer together than the rest, a doubled pair, and after them came a slightly wider gap. He fetched the calipers from his desk and felt foolish doing it. On the scaled images the ridges ran six and a half millimetres apart, both times. The doubled pair was two millimetres apart, both times.
“It’s the same wound,” he said. “The edges of the original injury are the template. Whatever forms over it takes the shape of what’s underneath. It would be stranger if it were different.”
“Would it?”
“Scar tissue does that.”
“I believe you,” Susan said. “Send them to Alex anyway.”
Alex took twenty minutes. When the tablet lit, both images were laid over each other on the screen, one in blue and one in orange, and wherever they matched the lines went grey. Almost all of it was grey.
“They agree to within the resolution of your photographs,” Alex said. “That includes the doubled pair. I want to be careful, because two pictures and a ruler aren’t a diagnosis. But I’ve been looking at this for a while, and I’ll tell you what bothers me. Skin that has been through two rounds of repair, with a dressing rubbing on it and a man sleeping on it, shouldn’t hold a pattern that precisely. Yours does. I don’t know what does that.”
David looked at the grey lines.
“There’s a third one starting,” he said. “I noticed this morning.”
Nobody spoke for a moment.
“Then you keep it when it comes off,” Susan said. “Where’s the last one?”
“Bathroom bin. It went out with the rubbish on Tuesday.”
She looked at him a moment longer than the answer needed. “And you see someone. This week, David.”
He did not argue. The institute’s medical service gave him a dermatology referral and an appointment twelve days out, and Susan put a specimen jar on the bathroom shelf beside the toothpaste.

The third one came away two days before the appointment.
It lifted in the evening while he was washing. He caught it this time, across his wet palm, and reached for the jar with his other hand. The lid was tight, so he set the strip down on the dry counter beside the basin to use both hands. Water ran off his fingers and pooled around it.
Its edges curled.
Drying, he thought. But that was the wrong way round, because it was getting wetter. Surface tension, then. A thin film will crawl when water moves under it. He had his thumb on the jar lid and was still working out the physics when the strip moved an inch along the counter toward the wet washcloth by the tap.
It stopped where the puddle ended. Between it and the washcloth lay a hand’s width of dry laminate. The near edge of the strip lifted slightly and came down again. Then the whole thing turned, slowly, and went the other way around the soap dish, along the thread of water that had run from his wrist.
David put the jar down, picked up the tooth glass, and set it over the strip, his hand not quite steady.
He stood there breathing. After a while he slid the glass an inch, to see, and the strip did not slide with it. It had flattened itself to the counter. He tilted the glass and lifted the rim.
It came up with the glass. It was holding on to the inside.
“Susan,” he said, and then louder.
She came in with a dish towel over her shoulder and stopped. He did not have to explain. The strip had let go of the glass and was moving again across the wet laminate, and its ridges rose and settled one after another along its length as it went.
“Don’t touch it,” she said.
“I already did. I had it in my hand.”
“Don’t touch it again.”
They got it into the jar with a spatula and the lid of a food container, neither of them using bare hands, and Susan screwed the top down and wound tape around the seam. Through the plastic it lay folded against the side, glistening. Then it was still.
Susan washed her hands for a long time. When she had dried them she stood under the light and looked at her left thumb, turning it. There was a small split beside the nail, the kind she got every winter. It was the hand she steadied his ribs with when she changed the dressing.
David saw what she was looking at. She saw him see.
“It’s probably nothing,” she said.
“You’ll tell them.”
“Yes.”
He filmed the jar and sent the film and the earlier minute from his phone, which Susan had thought to start recording while he stood staring. Alex called within moments.
There was a pause on the line before Alex spoke. David had expected the analysis first. He could have given it himself. The strip had changed direction toward moisture, and that was what distinguished movement from a curling film.
“Susan is there with you?” Alex said.
“I’m here,” she said.
“Good. Stay together. I’m going to call the medical service’s after-hours line and then the biosafety officer, in that order, unless either of you objects. Leave the jar where it is. Don’t open it and don’t put it in the refrigerator. I’ll have a courier with a proper container at your door, and David will be seen tomorrow morning and not on Thursday.” Another pause. “It turned around the soap dish. I watched it four times. I’m sorry, David. I’d have liked to be wrong about the photographs.”

Dr. Michael Grant had a narrow examination room and a habit David noticed at once. He did not sit across the desk. He wheeled his chair around until it stood beside David’s and angled the screen so they were both looking at the same picture.
“Before I tell you what I think,” he said, “tell me what worries you.”
David had prepared an account. It had dates and measurements in it. What he said was, “It moved.”
“All right.” Grant nodded as though that were a clinical finding, which David supposed it was. “Let’s look at where it came from.”
The wound looked pink and closed, with the faint brown haze of a fourth film beginning over it. Grant examined it under magnification for a long time. He pressed the skin on either side and watched how it blanched, and he asked about the fragility and the tiredness and wrote both down without comment. He took two punch biopsies, one from the line and one from a finger’s width beside it, and the second seemed stranger to David than the first.
“You think it’s wider than it looks.”
“I think I don’t know how wide it is,” Grant said. “So I’m asking.”
Susan was seen in the next room by a colleague. Her thumb was photographed and examined, and she was given a date to come back, a sheet of things to watch for, and a telephone number. She came out folding the sheet into quarters.
The specimen had gone to the institute overnight in its sealed container. By the afternoon there were more people involved than David had met: a pathologist named Ife Oyelaran, the biosafety officer, an infectious-disease physician who joined by video and said very little, and someone from the county health department whose camera stayed off. Alex ran the session. On the shared screen the droid’s arms moved inside the observation enclosure. They set the container down and released its lid, then lifted the strip with a broad soft-tipped tool and laid it in a shallow dish under the lens.
“Hydrating now,” Alex said.
A drop of water spread across the dish and touched the edge of the strip.
It contracted. David had seen it crawl on the counter, but this was different. Magnified, the movement began at the hip end, at the doubled pair, and travelled the length of the strip, each ridge tightening in turn after the one before it, and then the whole thing relaxed.
Nobody on the call said anything.
“It’s a colonial arrangement,” David heard himself say. His voice sounded like his lecturing voice, and he was grateful for it. “Repeated units along an axis, coordinated contraction. You see it in some colonial marine animals. Each of those ridges could be a unit. The coating over them is throwing me, because it looks like epidermis, but it’ll be material it picked up from the wound bed—”
“David,” Alex said. “You’ve called it a coating four times. What you’ve seen is that the outer layer contracts with the rest. I’d keep what you’ve seen and what you’ve named it apart for now.”
He stopped. On the screen the outer layer was contracting with the rest.
Grant had not moved his chair. “Can I ask you something? Are you more worried about the wound, or about what came out of it?”
David opened his mouth to answer and found he could not divide them. He shook his head.
“That’s fair,” Grant said.
The county health officer finally spoke, a woman’s voice, unhurried. “Dr. Miller, I need to know about the earlier ones. How many came off before this, and where did each one go?”
“Two. The first went down a shower drain at a rental house in the Caymans. I can give you the address.” He rubbed his eyes. “The second was at home. I put it in the bathroom bin, I think. That would have gone out with the rubbish weeks ago.”
“You think.”
“I think.”
“We’ll come back to that,” she said.
Oyelaran rang Grant’s office before they left. Grant put her on the speaker. The first sections from the biopsies were only preliminary, she said, and she would want to see more. But there were fine structures running through the upper layers of the skin in both samples, including the one taken from skin that looked normal. They were organized and alive, and she did not think they were his.

The week that followed was the longest David could remember.
He was not ill. That was the difficulty. He went to the institute and was sent home, because he could not work on his own specimen and could not think about anything else. He read papers without taking them in. He checked his dressing in the bathroom mirror and then tried not to check it for an hour, and then checked it.
Grant had replaced the pad with a clear film so the clinical team could watch the site without disturbing it. It meant David could watch it too. Under the film the brown haze thickened day by day. By the third day there were ridges.
On the second evening Susan made a proper dinner, and they were halfway through it, talking deliberately about her sister, when the tablet chimed.
“I can call back,” Alex said.
“No,” David said.
“The first sequencing run found your DNA in the specimen. A lot of it.” Alex went on before he could speak. “And before you say it, yes. It came off an open wound. It was lying in your blood and your skin cells for two weeks. Finding you on it tells us very little.”
“Contamination,” David said. He was aware of relief, and of clutching at it. “That’s all that is. Surface contamination.”
“It may be. So the droid is taking material from the interior of the specimen, washed, under controls, and Dr. Oyelaran’s laboratory is doing the same independently so that we aren’t just agreeing with ourselves. It will take some days. I thought you would rather have half a result than wonder what I was sitting on.”
“I would.”
