    "abstract": "The fluid-filled semicircular canals (SCCs) of the vestibular system are used\nby all vertebrates to sense angular rotation. Despite masses spanning seven\ndecades, all mammalian SCCs are nearly the same size. We propose that the SCC\nrepresents a sensory organ that evolution has `optimally designed\u0027. Four\ngeometric parameters are used to characterize the SCC, and `building materials\u0027\nof given physical properties are assumed. Identifying physical and\nphysiological constraints on SCC operation, we find that the most sensitive SCC\nhas dimensions consistent with available data.",
