Hermit crabs developed ultra long penises that can grow to 60% of their height

Hermit crabs developed ultra-long penises that can grow to 60% of their height so that they can have sex without leaving home & # 39;

  • In a new study, the researcher measured the penis-body ratio of more than 300 crabs
  • The study assumed that scratching with more valuable shells has a longer penis
  • This is because crabs have to leave their shells unattended during sex
  • Research showed that the length of the penis seemed to correlate with the importance of the scale

Some hermit crabs do everything to make their withdrawn reputation come true.

According to a new study, a few species of hermit crab seem to have developed extra long penises that allow them to have sex with others from the comfort of their hiding place.

In some cases it was observed that the crustaceans had penises that measure more than half of their body length.

This corresponds to the so-called "private parts for private property" hypothesis, which predicts that scratching with more losses (or, a more "valuable" scale) will have larger penises so that they can scale does not have to be left behind during sex and risk being stolen.

In a new article published by Royal Society Open Science, Mark Laidre of Dartmouth College tries to delve into the & # 39; rarely researched & # 39; relationship between private property and evolution of the size of the penis.

For hermit crabs, that private property is the coveted shell.

According to Laidre's new hypothesis of private areas for private property, developed extensive penalties to prevent property theft during sex & # 39; in animals such as hermit crabs.

When hermit crabs have sex, the two individuals stand in a way that places the openings of their shells face-to-face.

Then the male ejaculates in the female's shell.

To do this, the male hermit crab must step out of its own shell, at least partially – keep the scale open for thieves.

In theory, the researcher suggests that longer penises can enable individuals to make contact with sexual partners while at the same time having a secure grip on their property with the rest of their body, making them protect property from thieves during sex. & # 39;

To test the hypothesis, Laidre measured the ratio between penis and body of more than 300 hermit crabs from a total of nine different species.

WHAT IS THE HYPOTHESE OF PRIVATE PARTS FOR PRIVATE PROPERTY & # 39;

In a new article published by Royal Society Open Science, Mark Laidre from Dartmouth College introduces a hypothesis called "private parts for private property & # 39 ;.

The hypothesis predicts that enlarged penises developed to prevent theft of property during sex & # 39; in animals such as hermit crabs.

For hermit crabs, that private property is the coveted shell, which is often left unattended and runs the risk of being stolen during copulation.

The study suggests that a few types of hermit crabs seem to have developed extra-long penises that allow them to have sex with others from the comfort of their shell house.

And he found their relative penis size correlates with the value of their belongings.

"Species with more valuable, easier-to-steal properties had a significantly larger penis size than species with less valuable, less easily stolen property, which in turn had a larger penis size than species that did not carry any property at all," says Laidre.

The researcher says that hermit crabs with longer penises have probably developed the property to allow safe sex & # 39 ;, so that they can stay on their home by extending a long penis outside the scale in order to copulate & # 39 ;.

And, Laidre notes, the same may be the case for other species.
