White, James – Sector General 03 – Major Operation

“No need, Doctor,” said the Melfan. “The teeth have decayed and are quite soft and brittle. You can simply drive through them and we will follow.”

Edwards allowed the cruiser to sink to the floor, then moved it forward at a comfortable scuttling pace for Melfans. Hundreds of the long, discolored plant teeth snapped and toppled slowly through the cloudy water before they were suddenly in the clear.

“If the teeth are a specialized form of plant life,” said Conway thoughtfully, “they occupied a very sharply defined area, which suggests that someone is responsible for planting them.”

Grunting assent, Edwards checked to see that everyone had come through the tunnel they had just made, then he said, “The channel is widening and deepening again, and I can see another presumably specialized form of plant life. Big, isn’t it? There’s another. They’re all over the place.

“This is far enough,” said Conway. “We don’t want to lose sight of the way out.

Edwards shook his head. “I can see openings on both sides just like this one. If the place is a stomach, and it looks big enough, there are several inlets.”

Angry suddenly, Conway said, “We know that there are hundreds of these mouths in this dead section alone and the number of stomachs is anybody’s guess-great, flat, hollow caveins miles across if that radar isn’t telling fluorescent lies. We aren’t even nibbling at the problem!”

Edwards made a sympathetic noise and pointed ahead. “They look like stalactites that have gone soft in the middle. I wouldn’t mind taking a closer look.”

Even the Hudlar went out to have a closer look at the great, sharply curved pillars which supported the roof. Using their portable analyzers they were able to establish that the pillars were a part of the strata beast’s musculature and not, as they had earlier thought, another form of plant life-although the surface of all the muscular supports in the area were covered with something resembling outsize seaweed. The blisters were nearly three feet across and looked about ready to burst. A Melfan taking a specimen of the underlying muscle accidentally touched one and it did burst, triggering off about twenty others in the vicinity. They released a thick, milky liquid which spread rapidly and dissolved in the surrounding water.

The Melfan made untranslatable noises and scuttled backward.

“What’s wrong?” said Conway sharply. “Is it poisonous?”

“No, Doctor. There is a strong acid content but it is not immediately harmful. If you were a water breather you would say that it stinks. But look at the effect on the muscle.”

The great pillar of muscle rooted firmly to both floor and roof was quivering, its sharp curve beginning to straighten out.

“Yes,” said Conway briskly, “this supports our theory about the creature’s method of ingestion. But now I think we should return to Descartes-this area may not be as dead as we thought.”

Specialized teeth plants served as a filter and killing barrier to food drawn into the creature’s stomach. Other symbiotic plants growing on the muscle pillars released a secretion which caused them to stiffen, expand the stomach, and draw in large quantities of food-bearing water. Presumably the secretion also served to dissolve the food, digest it for assimilation through the stomach wall or by other specialized plants- they had taken enough specimens for Thornnastor to be able to work out the digestive mechanism in detail. When the power of the digestive secretion had been diluted by the food entering the stomach their effect on the muscles diminished, allowing the pillars to partially collapse again and expel undigested material.

Blisters were beginning to rupture off the other pillars now. By itself that did not mean that the beast was alive, only that a dead muscle could still respond to the proper stimulus. But the cavern roof was being pushed up and water was flowing in again.

“I agree, Doctor,” said Edwards, “let’s get out of here. But could we leave by a different mouth-we might learn something from a stretch of new scenery.

“Yes,” said Conway, with the uncomfortable feeling that he should have said no. If dead muscles could twitch, what other forms of involuntary activity were possible to the gigantic carcass? He added, “You drive, but keep the cargo hatch and personnel lock open-I’ll stay outside with the e-ts .
