The dimensions and sensitivities of semicircular canals.

With this definition it is possible to compare the mechanical sensitivities of all semicircular canals. For this purpose three different approaches seem feasible. (1) The effect of growth of one particular semicircular canal on G in one species. (2) Comparison of values of G for the three semicircular canals in one species. (3) Comparison of values of G of the horizontal canal in different species. Measurements of the geometry of the labyrinth of the pike have therefore been made. At the same time we studied the increase of the geometrical parameters of semicircular canals of the growing pike in relation to the bodylength of the animal. For the comparison of different species values of G were deduced from the literature.
