Observations have shown that amphibian larvae, contrary to what has been stated in the literature, have different kinds of eye movements. All of the anurans observed ( Xenopus, Rana, Bufo, Hyperoleus and Bombina ) have some kind of reflex eye movements effected through stimuli from the labyrinth organs as a response to movements of the body, while only Rana and Bufo have spontaneous scanning movements. Of the urodelians ( Ambystoma and Triturus ), larvae of Ambystoma have no observable eye movements, while Triturus larvae have reflex eye movements associated with movements of the neck, as well as spontaneous scanning movements; both kinds of movements differ from those seen in Anura.
