Strike a pose. Be fierce. Model.

Caenorhabditis elegans  are transparent roundworms that are used extensively as "model" organisms in research.  They are multicellular eukaryotic organisms (just like humans) that are cheap, easy to grow, see-through, and scientists have mapped out the fate of every cell- making them a perfect model system to study biological processes. 

C. elegans are fun- watch and SMILE!
