He examined what was left of its head, damaged badly by the shotgun blast that had killed it, a blast that would have disintegrated a human skull. The head was large in proportion to the animal’s size, and very angular, almost wedge-shaped, narrowing sharply at the front. Its remaining eye was unlidded, glistening beneath a viscous gel, like a polished, wet stone. It was black from head to toe, with stripes of a slightly lighter shade that were mostly visible as differently textured skin. The surface of the skin itself was slick with some type of dark secretion, which it seemed to be oozing from millions of tiny pores.
Whatever it was, it was unlike anything McCarter had ever seen or heard of. Even the shape was foreign. The body was all angles, like overlapping plates. The arms and legs were thick, but the joints were simple and exposed, like hinges on a door, one slot for the lower half and one slot for the upper. Muscular sinew could be seen where they bent, like bundled wires in a conduit. The severely pinched neck seemed almost insectlike and behind it stood distinct rows of stiff, bristlelike hairs that grew in a converging V-shaped pattern.
An evil-looking thing, McCarter thought, with all the tools of a predator: stereoscopic vision, a sleek, strong body, claws that resembled angled steel blades. Its mouth hung open on a set of powerfully muscled jaws and was filled with teeth like sharpened railroad spikes.
McCarter looked up toward the ceiling, upon which the animals had been crawling. The image of that ancient Mayan painting came to him, humans standing erect on the ground, blithely unaware of the Xibalbans directly beneath them, walking inverted with their feet on the underside of the earth’s surface.
As he shook off a chill, Danielle and Verhoven came up beside him, gawking at the thing, just as he had. Danielle seemed especially interested in the entry wounds from Verhoven’s shot. The damage resembled a pane of glass punctured by an errant baseball, with long fissures radiating from the wounds.
With the barrel of her rifle, Danielle reached out and pushed on the body. It was stiff. She tapped on it. It almost sounded hollow. “An exoskeleton,” she said. “Bones on the outside. Large animals don’t grow like this. Only insects and crustaceans.”
“It’s a damn gogga, then,” Verhoven said, using the Afrikaner slang for crawling bugs.
McCarter nudged Verhoven and pointed out a broad purple smear on his jacket, where the animal had hit him. The fibers of the coat were fraying and discolored, as if the smear was corrosive.
“Some kind of secretion,” Danielle said. “It’s all over the body of this one.”
As Verhoven pulled off the field jacket and tossed it aside, Danielle leaned closer to the animal. “Do you smell that?”
McCarter nodded. “Almost like ammonia,” he said. “I smelled it when the other one attacked us last night. But this is a lot stronger, even though this one is smaller.”
Danielle nodded, looking back toward the pools by the dam. “I was thinking the same thing,” she said. “And I think I know why. Ammonia is a base, an acid neutralizer. I think that’s what this thing is secreting—only, from the way it’s destroying that fabric, I’m guessing it’s a lot stronger than ammonia.”
“What good would that do them?” Verhoven asked.
Danielle nodded toward the pools. “That’s how they survive. They secrete this stuff to counteract the acid.”
McCarter remembered trying to help his son learn chemistry and repeated trips to the science department to ask fellow professors questions he could not answer. Bases were just as dangerous as acids. When the two were combined they would neutralize each other, but individually acids were corrosive and bases were caustic. Both were horrendously destructive to organic tissue and to materials far stronger than human skin. He turned to Danielle. Her calf was exposed where she’d cut off the torn section of the pant leg. Her skin was red but not blistering. “What about your leg?”
Danielle looked down; she guessed the torn section of her pant leg was fraying like Verhoven’s jacket, although she’d discarded it into the darkness somewhere. “I put peroxide on it,” she said. “I was thinking about infection, using it as an antiseptic, but peroxide is an acid, to some extent, it must have counteracted any of the base that got on my skin. It does feel strange though, almost like it were burning with a cold fire, like peppermint on the tongue.”
“Might want to use some more peroxide,” McCarter said.
As Danielle pulled out the plastic bottle, Verhoven held his hand out over the dead creature. “Notice anything else?” he said, looking at Danielle.
She shook her head.
“Dead animals radiate heat,” he said. “When you take one down, you can feel it pouring from the wounds. But not this thing.”
“What does that mean?” she asked.
