Title: A Note on the Structural Organization of the Cardiac Myofiber in Nautilus pompilius

Abstract: The ultrastructure of the cardiac myofiber in Nautilus resembles
that of bivalves more than the decapod cephalopods. The fiber is nonstriated, the
mitochondrial density is relatively small and the cristae poorly developed, and
the sarcoplasmic tubule system is either sparse or absent. These features suggest
that the Nautilus heart is not highly adapted to enhance the transport of large
volumes of oxygen to the tissues and that the adaptations found in the decapods
arose within the class Cephalopoda.
