dc.description.abstractThe 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.
