Abstract
The lungs of eight fraser’s dolphin
( Lagenodelphis hosei ), three Risso’s
dolphin( Grampus griseus),three Dwarf
sperm whale(kogia simus),one
bottlenose dolphin( Tursiops truncatus)
and one finless porpoise ( Neophocaena
phocaenoides) were examinated. The
cetacean lungs , unlike those of the other
domestic species, are not clearly subdivided
by deep interlobar fissures into lobes,
although there are occasionally external
indications of a lobar arrangement. However,
the right and left lung may be bilaterally
considered to consist of two lobes, namely an
apical (cranial) and a diaphragmatic (caudal).
Both lobes are united to form a single one.
The middle and accessory lobe bronchioles
are lacking on either side. The principal
bronchus of right apical lobe is solitary
arising from the trachea. Despite of the right
apical lobe, the remaining principal bronchi
of right and left lobe are bifurcation from the
trachea.
