Was looking up golden moles and followed a link to tenrecs and found this gem:
Unusual among placental mammals, the anus and urogenital tracts of tenrecs share a common opening, or cloaca, a feature more commonly seen in birds, reptiles, and amphibians. They have low body temperatures, sufficiently so that they do not require a scrotum to cool their sperm as most other mammals do.
Evolution blows my mind!
And both of these wittle animals are adorable. FYI
