DESCRIPTION:In recent years\, we have studied locomotion and shape control
  in Euglena gracilis using a broad range of tools ranging from theoretical
  and computational mechanics\, to experiment and observations at the micro
 scope\, to manufacturing of prototypes.<br> <br> As a concrete example\,  
 the behavior of Euglena gracilis is particularly interesting.This unicellu
 lar protist is particularly intriguing because it can adopt different moti
 lity strategies: swimming by flagellar propulsion\, or crawling thanks to 
 large amplitude shape changes of the whole body (a behavior known as metab
 oly). <br> <br> We will survey our most recent findings [1-4] within this 
 stream of research.<br> <br> This is joint work with M. Arroyo\, G. Ciccon
 ofri\, A. Lucantonio\, and G. Noselli\, and is supported by ERC Advanced G
 rant 340685-MicroMotility.<br> <br> <br> References<br> [1]	Rossi\, M.\, C
