1. Lymphatic vessels were found in the testicular rete mirabile of Sarcophilus and Macropus.
2. The larger species within each family have a greater number of testicular vessels.
3. Habitually upright species have more retial vessels than quadrupeds.
4. Larger species within each family have a lowerbody temperature.
5. The form of the rete and cremaster muscle suggests a pumping function for this complex.
