Abstract: The number of sealariums increases in the Irkutsk Region and as a consequence more Baikal seals become the patients of animal clinics. The morphological features of the anatomy of these endemics have a great importance in diagnostics, preventive measures and treatment, and they are understudied. The research target was the Baikal seal. The material of the investigation was spleens of 9 seals at the age of 5 months to 2 years. Anatomical and histological methods were used and the obtained data was processed statistically. The research objective was the investigation of the anatomic and topographic features of the spleen, extraorganic and intraorganic blood circulation in the Baikal seal. The spleen is located in the left hypochondrium of epigastrium, and it is of an oblong shape and a dark-violet color. The spleen of the Baikal seal is vascularized by extraorganic and intraorganic vessels. The main source of blood circulation is a splenic artery which is the first vessel of a celiac artery and is situated along the organ. The primary trabecular arteries penetrate from the splenic artery to spleen parenchyma and then they divide bifurcationally into arteries of the secondary order. The splenic artery ends trifurcationally. The peculiarity of extraorganic and intraorganic blood circulation of the Baikal seal is a big diameter of arteries which is perhaps connected with the habitat conditions and physiology of the organism. The microvasculature of the organ is presented by trabecular arteries which go along trabecules. The arteries of the pulp are the next element of microcirculation from which the central arteries go and divide into hemocappilaries falling into venous sinuses of a red pulp.
