Distal Excurrent Ducts and Penile Morphology of the Urogenital System in the Mississippi Mud Turtle, Kinosternon subrubrum hippocrepis (Chelonia:Kinosternidae)

We examined the distal excurrent ductal morphology and penile anatomy of the urogenital system in the Mississippi Mud Turtle, Kinosternon subrubrum hippocrepis, from a small sample of individuals collected in Arkansas in order to provide additional information regarding turtle urogenital anatomy. Specifically, we focused on the basic anatomy and histology of distal excurrent ducts (ductus deferens and ureter), associated structures (urogenital papillae), and penile histology in this kinosternid turtle. In addition, we provide an overview of the gross urogenital anatomy in this turtle, given that little detailed information exists on this topic in the chelonian literature.
