The picture shows three different cells of a healthy, 30-year-old male Chinese giant salamander:
an old lymphocyte on the top with a round-shaped nucleus, an erythrocyte in the middle and a thrombocyte with vacuolated cytoplasma beneath.
A highly granulated azurophil with a diameter of 45 micrometer.
The picture shows two stages of erytrhocytes. The cell with the grey-blue cytoplasma is a young erythrocyte. In comparison to the other erythrocytes its nucleus has a larger diameter and the chromatin is less dense.
Heterophil with a tree-lobed nucleus.
