Macroscopic Anatomy of the Saimaa Ringed Seal ( Phoca hispida saimensis) Lower Respiratory Tract
ABSTRACT We studied the macroscopic anatomy of the lower respiratory tract of the endangered Saimaa ringed seal ( Phoca hispida saimensis ). Examination of one adult and one young individual found dead showed that trachea had 85 and 86 complete cartilage rings. The adjacent cartilages exhibited very...
