Another sex question. Does anyone know how to tell a male spider from a female spider?

Females are bigger than males i think is one way

Spread their little legs apart and look.

I don’t want to even know. and change your damn avatar! it gives me the heebie jeebies!

Buy a male and female spider and put them together in a terrarium for some spicy spider sex.
Go do the dishes.
Return and check the glass box.
The one that isn’t there anymore was the male.

In many but not all cases, male spiders are significantly smaller than females. The difference in size is so extreme that some males and females were classified as completely separate species because they looked so dissimilar.

“All spiders use a unique form of mating, in which the male transfers sperm to the female using specially modified appendages near the mouth, called pedipalps. Because of this, it is easy to tell what sex a spider is: Female spiders have pedipalps which look like short legs, whereas male pedipalps look like “boxing gloves”.” Source

And then there is this.
And this is just weird

Darn it, @syz beat me to it. :( Although, I was just going to say that male spiders have larger pedipalps without all the other details.

I’ve got your spider sex right here!

The bigger ones are usually the females!

@syz
Weird tho it may be, it does make a certain amount of sense. The males who were the most “obedient” were the ones with the greater percentages of success and offspring.

@syz, thanks for the awesome links.

To everyone else, I was going for the pedipalps, so those who guessed that are right, as not all spiders have a size difference between males and females.
