Aquatic Mammals
Abstract Twenty neonatal harbor seal (Phoca vitulina) pups in rehabilitation following maternal separation underwent serial echocardiographic studies to assess patency and subsequent age of functional closure of the ductus arteriosus (d.a.). B-mode, color-flow Doppler, and pulse and continuous wave...

Closure of the f.o. was not confirmed in any harbor seal prior to release back into the free-ranging population.
