Overview
Halfmoon (tentatively Moliform luna). Large forage fish that strains plankton from seawater and nibbles at small growth. A staple prey species with several flee-and-hide behaviors evolved in response. A rigid beak protects two valves that draw in seawater for feeding; spiracles behind the eyes feed water to internal gills for breathing. Body is packed with neuromasts to detect water flow; anterior fins have fenestrae (holes) to help it quickly reverse direction. Peculiarly, it lacks reafference cancellation — it cannot distinguish stimuli caused by its own motions from changes in the surrounding world, making it easily fascinated by bright light. Edible; Fabricator cook recommended.
Survival
Ignore it. It will not bother you unless cornered.
