Submariner — Sea Life

The Auralattice Prism Cuttle listens with its whole body, catching engine hum and crew song in translucent fins that flicker like stained glass. Its mantle carries a living grid of light that seems to solve small pressure problems before the instruments notice them. Crews prize the creature for the calm it leaves in power systems, though the cuttle itself always vanishes before anyone can decide whether it was studying them or tuning them.
