one of the ways in which we describe
clamshells uh
involves their teeth so just like we
have teeth um clams have segmented parts
along one edge of the shell that are
places where the shell
partly fit together and so there's a
straight line of dentition or short
segments here that reflect uh what we call
dentition or teeth so that's one type
in one type of clam and in a different
kind of clam there's a shorter set of
teeth so you still see the tiny little
dentition or segments but it is
different from what we saw in the other
shell and those are some of the kinds of
features or characteristics that we look
for um in shells uh to describe and
distinguish between types
