These guys are the coolest spiders around! They have eight eyes, with three separate functions.
The large "headlight" eyes act as telescopic lenses- that's why you can actually make eye contact with them. They see very well with this set.
The eyes right next to the large ones act as rangefinders to gauge distance to prey.
And the last four on the back of their "head" are used bascially to keep an eye on everything else, so nothing can sneak up on them. (I'm sure you've seen them constantly turning to face you when they see you.)
I'm always helping the littler guys up out of the sink, because they seem to have a hard time climbing out. The hard part is getting them on my hand without hurting them. (Then, I promptly deposit them amongst my nearest plants.)
Spiders...creepy, fascinating, and most of all, our allies in the fight against the insect hordes!
PS, Here's a picture of my favorite jumper- Phidippus audax. Their English name is "Audacious jumping spider."
I moved to Texas from Canada where we have very few bugs of any sort. One of these jumping spiders was in our bathroom. I asked my husband to 'get' it for me, and it jumped left, right and all around. He almost screamed like a girl. "Spiders are NOT supposed to jump!" Now we know, and are prepared for them.
All spiders will bite if provoked - some are just more passive than others. It will surprise many to read tarantulas are one of the mellowest of the spider types - those kept as pets apparently seem to enjoy being petted! Jumping spiders by nature are more curious than aggressive.
