The semicircular canals of the inner ear are used for equilibrium balance. The shape
of the canal system can influence its function. Researchers have found that fast
moving mammalian species tend to have a roughly circular shape for the canal
system (mean length to width ratio of 1). Studies examining sloth anatomy theorized
that because sloths are slow moving, there is less functional demand upon the
equilibrium system, therefore they may deviate from this spherical shape (have a
more elliptical shape). Researchers measured the length to width ratio of the
semicircular canal system in 7 sloths.
