Interesting Facts About Spiders
1. Spiders have 8 eyes and 8 legs. 

2. Spiders have no bones.  

3. They have a hard outer shell called an ‘exoskeleton’. Because it is hard, it can’t grow with the spider. So young spiders need to molt, or shed their exoskeleton. The spider must climb out of the old shell. Can you imagine how hard it must be to pull all those legs out! As adults, they stop growing and do not need to molt.

4. Male spiders are usually smaller than females.

5. All spiders produce silk but not all spiders spin webs. Silk can be sticky, dry or stretchy.

13. Some people have a phobia of spiders (arachnophobia). Some of these fears of spiders are because people believe they are aggressive and will attack humans with little or no provocation.
