The crayfish has a cavity or "statocysts" lined with sensory setae or hairs.A grain in the cavity is pulled downward by gravity; the pressure against the bottom hairs of the cavity gives the crayfish a perception of being upright and,when it changes orientation,the grain touches side hairs that make it realize it is not upright.Thus,the crayfish "knows" which way is up in the dark.This sense is most closely related in function to the human sense of
