Title: Ontogeny of the hyobranchial apparatus in the salamanders <i>Ambystoma talpoideum</i> (Ambystomatidae) and <i>Notophthalmus viridescens</i> (Salamandridae): The ecological morphology of two neotenic strategies
Abstract: Comparison of metamorphosis of skull and hyobranchial system in two species of neotenic salamanders reveals two different types of neoteny. Ambystoma talpoideum is completely neotenic owing to delayed metamorphosis. Notophthalmus viridescens exhibits limited neoteny as a result of incomplete metamorphosis. Morphological details of neoteny are compared to life history in both species in order to discuss the ecological morphology of the two neotenic strategies. Comparisons to Taricha granulosa, Triturus vulgaris, and Ambystoma gracile indicate that these two strategies are widely employed and may represent familial patterns.
