I thought this was interesting article on nems and decided to post it here.

"Based on the appearance of the adult animals, the lower end of these animals has traditionally been called the foot and the upper end the head," explains Rentzsch.
What the research group found out was that in the sea anemone the "head gene" function is located at the end that corresponds to the "foot" of the adult animals. The key was to study the larvae of the sea anemones when theystill move around.

Makes sense if you think of an anemone as basically being an upside down jellyfish.
