Vestibular-induced eye movements were absent in larvae lacking anterior/utricular otoliths. Representative DIC images depicting lateral views of the inner ear of wild-type (A) and rock solo mutant larvae (B) at 5 dpf. The DIC images were oriented with anterior on the left and posterior on the right. Note the loss of anterior otolith in the mutant, whereas the posterior otolith is unaffected. Scale bar, 100 μm. (C) Amplitudes of eye movements of wild-type siblings and rock solo mutants.
