The neuromasts observed at hatching were the same size on the head and body in both species, indicating simultaneous formation during the embryonic period inside the egg; the cupulae grow in length as the larvae develop.
The relationship between the length of the cupulae of free neuromasts and feeding ability in larvae of the willow shiner Gnathoppogon elongatus caerulescens (Teleostei, Cyprinidae).
Concurrently, driven by the endolymph flow and the thermal expansion, the motion of the three cupulae can be written in terms of the displacement vector, d, as
Comprehensive grid convergence tests were performed to ensure sufficient spatial resolution of the generated solutions, and the results presented herein were obtained with a grid involving 7496 tetrahedral solid elements with 2078 nodes for the 3 cupulae and 68277 tetrahedral fluid elements with 18106 nodes for the endolymph.
An ampullopetal flow due to the buoyancy-driven natural convection is generated in the HC duct, an ampullofugal flow is generated in the two vertical semicircular canals, and an utriculopetal flow is generated in the utricle side regions of the three cupulae. Moreover, the endolymph velocity in the HC duct peaked 6.29 [micro]m/s is far greater than the velocities in the other regions.
The HC cupula slowly deforms to the utricle side by 2.44 [micro]m, and the AC and PC cupulae deform to the canal side by 0.372 [micro]m and 0.341 [micro]m, respectively.
