Meeting Abstract P3.96  Friday, Jan. 6  Feeding at the Air-water Interface: Biomechanics and Functional Morphology of Feeding in Funnel-mouthed Tadpoles (Megophryidae: Megophrys) ZENG, Yu; Univ. of California, Berkeley dreavoniz@berkeley.edu Larval anurans occupy a great variety of ecological niches, and accordingly they have evolved tremendous diversity of feeding mechanisms. The feeding apparatus of the funnel-mouthed tadpoles is among […]

Meeting Abstract P3.133  Friday, Jan. 6  Falling faster: Size and folding behavior decrease descent time in a brittle star (Ophiocoma aethiops) BADGER, M.A.*; JONES, M.A.; University of California, Berkeley; Florida State University, Tallahassee mbadger@berkeley.edu Fluid living organisms often undergo shape changes in order to move more effectively through the environment.
