Morphology and microchemistry of the otoliths of the inner ear of anuran larvae

摘要: To navigate in space most vertebrates need precise positional cues provided by a variety of sensors, including structures the inner ear, which are exquisitely sensitive to gravity and linear acceleration. Although these have been described many vertebrates, no information is available for anuran larvae. The purpose our study was describe, first time, size, complexity microchemistry saccular otoliths larva 13 species from central Argentina, using electron microscopy X-ray spectroscopy (N = 65). We concluded that a) differ area, perimeter, otolith relative size fractal dimension, but similar terms their when compared spatial guilds, b) nektonic larger than nektonic-benthic benthic c) species.
