The Cell Composition of the Peripheral Blood and Some Hematopoietic Organs in the Antarctic Starry Skate Amblyraja georgiana (Norman, 1938) (Rajiformes: Rajidae) from the Scotia Sea

  • 5 Accesses


The composition of leukocytes was studied in the peripheral blood and hematopoietic organs (kidneys and spleen) of the Antarctic starry skate Amblyraja georgiana (Norman, 1938). Cells of several types with different morphofunctional characteristics and structures were found in the blood smears: lymphocytes, monocytes, neutrophils and eosinophils, and blast cells. A leukogram analysis showed that the white blood of A. georgiana is of a lymphoid type. In the kidney and spleen, most cells are blast forms.
