Tarantula and molts
This is my pet spider Matilda, and her molted exoskeletons, so you can see how much she grows with each molt. For scale, each plastic dish is 3.5 inches (8.89 cm) across. Without looking it up, how large do you think this spider (Lasiodora parahybana) can get?

Microscopic, clam-shaped creature
Another microscopic creature from our desert puddles. One of its relatives played a very interesting role in World War II. What is it?

Tiny, scale-like objects
Another microscopic photo. These tiny structures define an entire group of organisms, even giving them their name. What are they from?

Praying Mantis
This Praying Mantis has taken up residence on my lamp, coming out every night to catch some of the insects the light attracts. Why are insects attracted to lights?

Black widow spider and baby spiders
My Black Widow Spider's egg case hatched, releasing hundreds of tiny babies. While prey animals tend to have lots of offspring, most predators tend to have relatively few offspring. Why do spiders have so many babies?

Baby spiders
Another egg case from my Black Widow spider just hatched. Notice that the babies are brown and white, instead of the characteristic shiny black with red markings. Why?
