A Model Analysis of Tensile Stress in the Toadfish Vestibular Membranes

Table 1

Live measurements of the toadfish labyrinth*.

Membrane structure	Mean thickness “𝑤” (max/min) in microns	Mean radius of curvature “𝑟” (max/min) in microns
Anterior Canal	70 (86/45)	307 (322/270)
Lateral Ampulla	58 (75/44)	697 (788/625)
Utricle	32 (42/20)	556 (654/469)

*Measurements were made during surgery in live fish reported elsewhere [4]. Mean values reflect 12–25 measurements from 3–5 fish along with maximal and minimal individual values. Utricle was measured at its narrowest point.
