Even zookeepers have a hard time telling male and female hyenas apart

Hyenas, famously known for their distinct looks and behaviors, have long puzzled zookeepers and researchers alike. One of the most perplexing aspects of these fascinating creatures is their reproductive anatomy. Female hyenas possess genitalia that closely resembles a male’s penis and scrotum, making it challenging even for experienced zookeepers to differentiate between the sexes.

Female hyenas, scientifically known as Crocuta crocuta, possess an elongated and protruding structure known as a pseudopenis. This remarkable adaptation is formed from the fusion of the clitoris and the labia, resulting in a phallic-like structure that can extend up to seven inches in length. The pseudopenis is so realistic in appearance that it even bears a natural opening, allowing it to mimic male urination.

This extraordinary genitalia presents a unique challenge for zookeepers and researchers attempting to identify the gender of hyenas. Unlike other mammals, where the presence of external genitalia clearly distinguishes males from females, hyenas possess remarkably similar-looking reproductive organs. The pseudopenis, coupled with the absence of obvious testicles, leaves zookeepers relying on behavioral cues and internal examinations to determine the sex of these remarkable creatures.

From an evolutionary perspective, the presence of a pseudopenis in female hyenas serves important purposes. It plays a crucial role in dominance and social hierarchy within hyena clans. The alpha female, the dominant member of the group, inherits a larger pseudopenis than her subordinate counterparts. This physical characteristic further reinforces her position of power and ensures her reproductive success, as the female hyena’s pseudo-phallus also doubles as the birth canal.

While the pseudopenis may surprise and confuse zookeepers, it is essential for the female hyena’s reproductive success. In childbirth, the size and strength of the pseudopenis allow the alpha female to deliver her cubs more easily. However, this unique anatomy also poses challenges during mating. Male hyenas must navigate the intricacies of the elongated structure to successfully engage in copulation, adding an extra layer of complexity to their reproductive behavior.

Female hyenas exhibit high levels of androgen, a male hormone, resulting in not only the development of a pseudopenis but also increased aggression and other masculine traits. This intricate balance of hormones and reproductive adaptations contributes to the dynamic nature and complex social structure of hyena clans, where females tend to dominate over their male counterparts.

The study and understanding of hyena genitalia have significant scientific implications, shedding light on the fascinating diversity of reproductive strategies present in the animal kingdom. By studying the intricate details of hyena anatomy, researchers gain insight into evolutionary adaptations, sexual selection, and the interplay of hormones and behavior.

In conclusion, female hyenas’ genitalia, resembling that of a male’s penis and scrotum, present a fascinating challenge for zookeepers and researchers attempting to determine the sex of these remarkable creatures. The presence of a pseudopenis not only confuses observers but also plays a vital role in hyena social dynamics and reproductive success. The study of hyena genitalia provides valuable insights into the complexities of the animal kingdom, shedding light on the diverse strategies employed by different species.
