@.extremenature: The Crab That Farms Its Own Food on Its Own Arms... One Degree From Death (Yeti Crab) It farms bacteria on its own claws. One degree too far from the vent — the farm dies. Two degrees — so does the crab. The yeti crab lives at 2,200 meters deep, between superheated vent fluid and near-freezing abyssal water. It waves its claws rhythmically through vent fluid to feed chemosynthetic bacteria — then scrapes them off its own arms and eats them. It must keep its claws within a thermal band of a few degrees. Continuously. It doesn't hunt. It doesn't scavenge. In one of the least habitable places on Earth, it didn't find food. It grew it — on itself.
