7 Animals with the Weirdest Genitalia on Earth

The subject of human and animal sexuality has always been personally fascinating. What nature does to compensate adversarial blockades in order to multiply is astounding.

7. Bush Crickets (katydids)

Imagine if a 200 pound man had testicles that weighed 28 pounds – and that was normal. Well, that is the case with bush crickets. Their testicles are 14% of their body weight!

Common in American and Australia, bush crickets can also be found in fewer numbers around the globe. Interestingly, the testicles widely vary in texture. They can be very spiky or prickly to very smooth. Perhaps this has to do with the variation of the female bush crickets’ female organs, who knows.

Unfortunately, this does not mean they have a large output of semen. Contrarily, they have a rather tiny amount of “ammunition”. The unusual size of the testicles has more to do with stamina. This is because male bush crickets have to endure very promiscuous partners. The female is known to mate as much as 23 times before she is satisfied with the outcomes.

6. Carabid Beetles

These beetles don’t follow the law of nature in regards to symmetry. They only have one testicle. This doesn’t seem to affect their breeding capabilities whatsoever. In fact, these types of beetles give more than just semen to their partner. Their accessory glands produce the semen before it goes into the testicle. The accessory glands have rich nourishment for the fertilized eggs, promoting their well-being and survival.

For reasons that researchers can’t explain yet, the left testicle is the one that is almost always missing. One thing researchers do know is that the accessory glands make for a tight squeeze in the already cramped abdominal cavity. Therefore, another testicle would likely seem redundant.
