What About Those Spiders?
July 29, 2010


Check out the photo again. Two spiders, right? One is a male and the other is a female, but which is which?

If you thought the female was the smaller one, think again. In the spider world, girls rule.

Many spider species are sexually dimorphic, which means that males and females look different from each other either in size or color or shape.  So the adult spiders look different because of their sex–hence sexually dimorphic .

For most spider species, the females are bigger and stronger–so much so that males are often thought of as lunch!  How’s that for girl-power?

Would you like to know more about spiders?  Stay tuned.


Miriam Schulman lives in Los Angeles and has observed, read about, photographed, studied, and raised spiders for over eight years! From September through November she takes live spiders into local public schools and teaches children in grades 3 through 12 about these important and fascinating creatures.

Maybe she’ll come to your school soon!
