- Abstract
The article presents a study on the characterization of reproductive anatomy and early embryonic detection in the northern fur seal or Callorhinus ursinus using ultrasonography in Saint Paul Island, Alaska. The study's aim is to determine the feasibility of transrectal ultrasonography for assessing the reproductive status of female northern fur seals in the wild and to provide preliminary description of the reproductive tract and early embryo in situ. Subjects used were female northern fur seals of adult size, where ultrasonography was performed by an experienced operator with the use of a portable ultrasound unit. An overview of the results of the study is offered.
