YES.  OLD, WORN TEETH AT FRONT END DISCARDED.  NEW ONES GENERATED IN REAR.

of small species?
I'M NOT SURE, BUT AGAIN, IT DEPENDS MORE ON WHAT THE SPECIES IS DOING WITH
IT.  HOWEVER, SAY, ALL HELICOSTYLIDS FEED ON MICROFUNGI OF BASICALLY THE
SAME SIZE AND CONSISTANCY, WHICH GROW ON TREE BARK OF THE SAME DEGREE OF
SMOOTHNESS (NONE OF WHICH IS TRUE).....I WOULD ASSUME THAT THE LARGER
SPECIES WOULD HAVE LARGER RADULAE.  WOULD AN EXCEPTION TO THIS 'RULE' BE
FOUND?  ABSOLUTELY!
