SUMMARY: (University of Miami): Surprising tradeoffs and consequences of lo
 comotion in simple\, enigmatic marine animals
DESCRIPTION:: Abstract: Animals are characterized by their movement\, and t
 heir tissues are continuously subjected to dynamic force loading. The adap
 tive response and mechanics of tissues determine the ecological niches tha
 t can be endured by a living organism. In the first part of my talk\, I wi
 ll present our surprising discovery of locomotion-induced tissue fractures
  and healing in a simple\, early divergent marine animal – the Trichopla
 x adhaerens. I will demonstrate how fracture mechanics governs dramatic sh
 ape changes and asexual reproduction in this animal.\nIn the second part o
 f my talk\, I will focus on the role of fluid mechanics in marine inverteb
 rates. Many marine invertebrates have larval stages covered in linear arra
 ys of beating cilia\, which propel the animal while simultaneously entrain
 ing prey. In starfish larvae\, we discovered that these ciliary arrays giv
 e rise to a beautiful pattern of slowly evolving vortices. I will elucidat
 e how these vortices create a physical tradeoff between feeding and swimmi
 ng in heterogeneous environments.\nFor more information\, please visit: ww
