Laterally positioned labia are set into vibration by a […]

Meeting Abstract 16.3  Tuesday, Jan. 4  You are what you eat: an analysis of morphological specializations to diet in iguanian lizards. HERREL, A*; VANHOOYDONCK, B; CRUZ, F; CNRS/MNHN; University of Antwerp; CONICET anthony.herrel@mnhn.fr Small lizards are typically considered opportunistic foragers on invertebrate prey showing little or no dietary specialization. However, recent studies have demonstrated that many small-bodied […]

Meeting Abstract 16.1  Tuesday, Jan. 4  Hips don’t lie: How the batoid pelvic girdle shape correlates with locomotion and phylogeny MACESIC, L.J.; Florida Atlantic Univ., Boca Raton, FL ljmacesic@gmail.com Batoids (skates and rays) exhibit several forms of locomotion. To swim, they perform axial undulation, pectoral fin undulation, or pectoral fin oscillation. On the substrate, benthic batoids perform […]
