Took this today....Appreciate any ID on this. What are they called? Are these the fighting spiders?
Anyway, followed some of the framing of other CS members, and trying them out. Appreciate any critique of the pics....DOF is max out for my camera at F8, and could not get a better angle to max it. Thanks for any comments/critique! And Happy New Year! #1 #2 #3 (BTW, is that an eye?) ![]()

Here are some info, which I just found: http://tolweb.org/tree?group=Saltici...group=Dionycha An Introduction to the Jumping Spiders Jumping spiders (Salticidae) are easily distinguished from other spiders by their four big eyes on the face and four smaller eyes on top of the head. Around the world there are probably more than 5000 species of jumping spiders. Jumping spiders are charming spiders that look up and watch you. Their excellent vision allows them to hunt much as do cats, spotting prey from long distances, creeping up then pouncing using their jumping ability. Although a jumping spider can jump more than fifty times its body length, none of its legs has enlarged muscles. The power for jumping probably comes from a quick contraction of muscles in the front part of the body increasing the blood pressure, which causes the legs to extend rapidly much as in the toy frogs that hop when you squeeze a bulb. Their vision also allows communications by visual means, such as the elaborate courtship dances that males perform. Salticids are perhaps as old and diverse as mammals, though not many humans know their world. Many salticids are colorful, they take on a variety of body forms, and some have disguises, looking like ants and other organisms. The bright colors and elaborate forms of some jumping spider species are involved in courtship. If you'd like to learn more about jumping spiders, you can follow the phylogenetic tree above to explore the diversity of species. You might also want to wander through a gallery of jumping spider images and movies, explore their anatomy, or focus on the jumping spiders of America north of Mexico. Jumping spiders have excellent vision, with among the highest acuities in invertebrates. The eight eyes are grouped four on the face (the two big Anterior Median eyes in the middle, and two smaller Anterior Lateral eyes to the side), and four on top of the carapace (two medium-sized eyes toward the back, and two very small eyes in front of them). You can think of the Anterior Median eyes (AME) as acting like our fovea, with high acuity but small field of view, and the remaining six eyes acting like our peripheral vision, with lower resolution but broad field of view.
