Elephant testes

The testes of elephants are completely inside the body, situated close to the kidneys and protected against cold temperatures, for example in cold water. This is one of the important indications of a previous water-living phase in the evolutions of elephantine animals.

Roger W. Short writes: "The elephant embryo (like the dugong and manatee) has no gubernaculum, no processus vaginalis, no pampiniform plexus, no scrotum, and hence no means of effecting testicular descent".
