When it comes to mammals, the presence of a hymen is a unique trait that is only found in two species. The first mammal with a hymen is the spotted hyena (Crocuta crocuta). Female spotted hyenas have a pseudo-penis that is actually an elongated clitoris, which makes it difficult to differentiate between males and females at first glance. The presence of a hymen in female spotted hyenas has been linked to their complex social structure and dominance hierarchy within their groups.

The second mammal with a hymen is the common mole (Talpa europaea). Female moles have a unique reproductive system where the hymen acts as a barrier to prevent dirt and debris from entering the reproductive tract during burrowing activities. This adaptation helps to protect the female mole's reproductive organs and maintain their fertility in their underground habitat.

These two mammals with hymens showcase the diversity of reproductive adaptations found in the animal kingdom. While hymens are commonly associated with human females, they serve different purposes in other mammalian species. Understanding the presence of hymens in these mammals can provide valuable insights into their reproductive biology and behavior.

Overall, the spotted hyena and common mole are the only two mammals known to have hymens. Their unique reproductive adaptations highlight the incredible diversity of the animal kingdom and the many ways in which different species have evolved to survive and thrive in their respective environments.

These incredible creatures offer a glimpse into the complex and diverse ways in which mammals have evolved to ensure the continuation of their species.
