Nature is full of fascinating and sometimes brutal adaptations, but few are as shocking as the birthing process of the spotted hyena. You might think childbirth is a universally painful experience, but hyenas take it to an entirely new level.
Female hyenas have one of the most unusual reproductive anatomies in the animal kingdom—what appears to be a penis is actually an elongated clitoris, known as a pseudo-penis. This rare adaptation makes mating, birth, and survival incredibly difficult for both mother and cubs.
Let’s dive into the science, struggles, and evolutionary mysteries behind why hyenas experience one of the most challenging births in the wild.
Hyenas’ Unique Reproductive Anatomy: A Bizarre Evolutionary Twist
The female spotted hyena (Crocuta crocuta) is unlike any other mammal when it comes to reproduction. Unlike most female mammals, hyenas have no external vaginal opening. Instead, their labia are fused together, forming a pseudo-scrotum, and their clitoris is elongated into what resembles a fully functional penis.
This means that both mating and giving birth happen through a narrow, tough, and inflexible canal—a structure that poses serious risks to both mother and cubs.
But why would evolution favor such an extreme adaptation? The answer lies in hyena social structure and dominance.
The Link Between Dominance and Reproductive Anatomy
Hyenas live in strict matriarchal societies, where females outrank males in dominance. The unusual reproductive anatomy is believed to be an evolutionary adaptation linked to social hierarchy.
- A Display of Strength: A larger pseudo-penis might act as a dominance signal, making it clear which females hold power in the clan.
- Hormonal Influence: Female hyenas have higher testosterone levels than males, leading to increased aggression and dominance over the pack.
- Mating Challenges: Males must earn the right to mate, as females control copulation with their complicated anatomy.

While this system gives females power, it comes at a terrible cost when it’s time to give birth.
Why Giving Birth Is So Dangerous for Hyenas
Imagine trying to push a newborn through a passage too small, too rigid, and highly prone to tearing. That’s exactly what female hyenas go through every time they give birth.
Here’s what makes hyena birth so deadly:
- A Super Tight Birth Canal
- The pseudo-penis acts as the only birth canal, but it is long, narrow, and lacks the elasticity of a normal vagina.
- This makes labor extremely difficult and painful, with a high chance of the tissue tearing.
- First-Time Mothers Face the Worst Risks
- Many first-time mothers do not survive the birthing process due to severe ruptures.
- Those who do survive often suffer from long-term damage to their reproductive organs.
- High Cub Mortality Rate
- A staggering 60% of hyena cubs suffocate before they are fully delivered.
- Since the birth canal is so tight, cubs often become trapped and die before they can emerge.
- A Painful Recovery Process
- After birth, the pseudo-penis often ruptures completely, forcing it to heal over time.
- Mothers suffer weeks of pain and vulnerability while their bodies recover.
Despite these brutal challenges, hyenas continue to thrive, and their unique reproductive system has remained largely unchanged for millions of years.
How Do Hyenas Mate? The Struggles of Reproduction
If you think birth is difficult for hyenas, mating is no easier. Males must overcome significant anatomical and social obstacles just to reproduce.
- Males Are Submissive to Females
- Unlike in many species where males dominate, male hyenas are the weaker sex in both power and ranking.
- They must approach females cautiously, often displaying submissive behavior to gain approval.
- Navigating the Pseudo-Penis
- Since females have no traditional vaginal opening, males must carefully maneuver through the pseudo-penis to copulate successfully.
- This requires both patience and precise positioning, making it one of the most complex mating processes in the animal world.
- Only the Strongest Males Get to Reproduce
- Males don’t fight each other for dominance like in other species. Instead, they must earn the female’s trust over time.
- Females choose mates based on persistence, patience, and respect, ensuring only the most determined males pass on their genes.
Given how dangerous and inefficient the reproductive process is for hyenas, one might wonder why evolution hasn’t corrected this issue.
The answer lies in survival strategy and social dynamics.
- Matriarchal Control Guarantees Stronger Cubs
- By limiting mating to only the most persistent males, female hyenas ensure that their cubs inherit strong genetics.
- This method prevents weaker genes from spreading, keeping the species robust.
- Higher Testosterone Helps With Survival
- The same high testosterone that makes birth difficult also makes female hyenas stronger and more aggressive.
- This aggression helps protect their cubs and maintain dominance in their environment.
- Fewer Cubs = More Resources
- Since many cubs don’t survive birth, the ones that do are often given more attention and resources.
- This ensures the strongest cubs make it to adulthood, increasing the clan’s overall survival rate.
The Resilience of the Spotted Hyena
Despite their brutal birthing process, hyenas have thrived for millions of years. Their ability to adapt, dominate, and survive proves just how powerful evolutionary trade-offs can be.
- They are among Africa’s most successful predators, competing with lions for food.
- Their clans are ruled by powerful females, ensuring only the strongest members survive.
- They have some of the most advanced social structures in the animal kingdom, making them highly intelligent and strategic.

Conclusion: Nature’s Ultimate Test of Survival
Hyenas are proof that nature often prioritizes survival over comfort. Their unique reproductive anatomy, extreme birthing challenges, and dominance-driven society have allowed them to thrive despite overwhelming odds.
While their birth process remains one of the most painful and deadly in the animal kingdom, it also ensures that only the strongest females and cubs survive.
So the next time you see a spotted hyena, remember—they’re not just fierce scavengers. They’re survivors of one of evolution’s toughest reproductive challenges.
Never ever kill a house centipede again if you find inside your home
When you encounter insects around your house, how does it make you feel? It’s understandable that your first instinct would be to snatch anything and run over them. Some of them carry dangerous poisons and can sting you brutally and fatally.
The creepiest ones make you feel the worst; you usually want to strangle those small, frightening animals with so many legs as soon as possible.
However, after reading this, you may be reluctant to kill those menacing-looking centipedes the next time you see them in your toilet.
It might be quite hard to resist the impulse to smash centipedes when you notice them crawling around the house. You can be shocked by centipedes. However, after learning how useful they have been around the house, you might wish to just express your gratitude by not killing them in the future.
It turns out that those squirmy, fast-moving organisms have been keeping other tiny insects out of your house. There’s a special kind of centipede around the house that has about 20 legs wrapped around its body and is slightly shorter than its other wormy brethren.
These tiny animals have acted as an undetectable pest deterrent for your house, keeping out ants, bedbugs, silverfish, spiders, and cockroaches. Their appetite is so great that they practically eat any arthropod they find about the house.
Centipedes are good guys, but that doesn’t mean you should open your doors and let them in in large numbers. Instead, it means you should be grateful to the one or two you find about the house and give them a free pass the next time they come.
They may make some noise when they are found, particularly if small children or even adults think they are disgusting and dirty. Let them go on their own or send them outside to munch some leaves instead of just squashing them.
Don’t squish every bug you come across inside your house to avoid the possibility of introducing hundreds of small baby spiders into your house. You really don’t want to see it.
Furthermore, centipedes aren’t all that terrible. They are only weak, small creatures that, aside from terrifying your heart, are hardly strong enough to cause serious harm.
Considering that they don’t actually spread germs throughout the house like other insects do will help convince you that they are genuinely good people.
Since centipedes are basically non-lethal, you shouldn’t be afraid of them either. However, we are unable to say the same regarding a few others. These insects cause a number of terrible diseases that are quite dangerous and could be fatal if properly treated.
Definitely keep an eye out for those. These are a few of the poisonous insects you should avoid coming into contact with indoors.
After being bitten, bullet ants give you the sensation that you have been fired, as their name implies. Therefore, you should try to avoid getting bitten. One of the largest ant species, they are commonly found in the rainforests of Nicaragua and Paraguay.
The problem is not the botfly itself, but rather its larvae, which are an inside parasite of many animals, including humans. The female deposits her eggs beneath the skin, and the developing larvae dig further into the skin, causing an infection that alters the tissue of the skin significantly.
According to some parents, they can feel the larvae scuttling inside their skin.
Fleas: Because they feed on blood, flea bites can cause itching, irritation, and sometimes even skin infection.
An invader may sustain agonizing white pustules on their skin for weeks after being repeatedly stung by the notorious fire ant. There are about 295 different species of ants. Some of them discharge toxic venom that might cause allergic reactions in certain persons.
Up to 12,000 people may die each year from the trypanosome cruzi parasite, which is spread by the kissing bug biting its victims’ lips.
The largest hornets are giant Japanese hornets, which may reach a length of 2 inches and have a deadly sting that kills about 40 people per year.
Tsetse Flies: An estimated 500,000 people die from sleeping sickness on the African continent as a result of being bitten by tsetse flies.
Killer Bees: Due to their immense numbers, killer bees usually launch aggressive, overwhelming attacks that are frequently fatal.
Driver ants: These ants use their powerful mandibles to strike with tremendous force. They may kill several animals in a single raid. In addition to attacking other insects, they have a horrible habit of biting humans.
Mosquitoes: Known as the deadliest insects and maybe the deadliest organisms on the planet, mosquitoes are believed to be responsible for up to one million deaths each year from diseases like yellow fever, encephalitis, West Nile virus, and malaria.
