The living story
The story so far
Its tail sits in near-boiling water while its head stays cool — the Pompeii Worm lives inside a temperature gradient that would kill any other complex animal. It grazes bacteria on the chimney walls at the very edge of what life allows, and it has never once flinched.
Happening now
It works the hottest rock of the vent field, head in cool water, tail in the fire. The grazers' quarter measures toughness in Pompeii units; nothing else scores above one.
What may come
The vents shift and die; chimneys crumble. The Pompeii Worm has survived a hundred vent deaths by being the toughest thing on the rock. The next chimney is already building, and the Worm will be there first.
