Is this what your describing? I can see the triangle head. Is the triangle head visible with the naked eye? http://acad.uwsuper.edu/Zoology/Tutorial/Planaria/Class_Turbellaria_Main~1.h tm I thought that planaria were these really small tube like white worms, about 1/2 inch long, that squiggled as they swam, and seemed to hang around the surface. Is this a different species? It says these use cilia to crawl with. The ones I have seen could swim too. Can yours swim?
