Abstract This paper describes
the variation
in shell
and pedicle morphology of three species of brachiopods. Two are
specialists
that live on hard or soft surfaces, respectively, and the third is a
generalist
that can live on either. The interaction between behaviour and
substrate
explains (1) the morphology of the specialists, (2) variability in the
lifestyle of the generalists, and (3) diversity in fossil brachiopods.
Keywords articulate
brachiopods; behaviour; pedicle;
post-Pleistocene marine
environments; Terebratulida
