Some information from Wikipedia

The jumping spiders (family Salticidae) contains more than 500 described genera and over 5,000 species, making it the largest family of spiders with about 13% of all species.[1] Jumping spiders have good vision and use it for hunting and navigating. They are capable of jumping from place to place, secured by a silk tether. Both their book lungs and the tracheal system are well-developed, as they depend on both systems (bimodal breathing).

Appearance
Jumping spiders are generally recognized by their eye pattern. They typically have eight eyes arranged in three or four rows. The front, and most distinctive row is enlarged and forward facing to enable stereoscopic vision. The others are situated back on the cephalothorax.

Behavior
Jumping spiders are generally diurnal, active hunters. Their well developed internal hydraulic system extends their limbs by altering the pressure of body fluid (blood) within them. This enables the jumping spiders to jump without having large muscular legs like a grasshopper. When a jumping spider is moving from place to place, and especially just before it jumps from one place to another, it tethers a filament of silk to whatever it is standing on. Should it fall for one reason or another, it climbs back up the silk tether.

Unlike almost all other spiders, they can quite easily climb on glass. This is because of the minute hairs and claws found on their feet, which grip minute imperfections in the glass. Jumping spiders also use their silk to weave small tent-like dwellings, where females can protect their eggs and to serve as a shelter while moulting.

Jumping spiders are known for their curiosity. If one approaches a jumping spider and attempts to place one's hand near it, rather than quickly scuttle away in search of cover, the arachnid will more likely than not, jump away and turn to face the hand. Repetition of this action may result in the spider jumping backwards but still eyeing the hand. Because of this contrast to other species, which will sense the hand and run for safety, the jumping spider is regarded as "curious" since the spider is interested in whatever approaches it.

Vision
Jumping spiders have very good vision centered in their anterior median eyes (AME). Their eyes are able to create a focused image on the retina, which has four layers of receptor cells in it.[3] Physiological experiments have shown that they may have up to four different kinds of receptor cell, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultra-violet range. Color discrimination has been demonstrated in behavioral experiments.

Hi JC

What a terrific macro work by you!
I was always impressed by these little creatures and equaly by the people that photographed as so their key features - their big eye - would be nicly visible.
I really like the sharpness of the details here, as well as the lighting.
The frontal POV is also great, as well as the DOF.
The vertical composition is interesing, perhaps even a bit wierd, but definately original ;)
Bravo and TFS

Hello Jitti,
I'm always so glad I'm bigger than this fellow's prey when I see pictures like this. Looks prehistoric in some way. But indeed a surprising composition and crisp sharp details. Nice work,
Jacob

Hi Jitti.
What a cute specimen you have pictured and it is very curious. Funny shot. Superb done in amazing dark key. You are quite right that have saved vertical cropping. Very impressive and nice picture. TFS and my compliments.
Alexei.

A truly remarkable macro of this small spider, JC. You deserve special appreciation for it.
All the hairy details on its body and particularly the eyes are very well rendered in this well-controlled shot.
Great work, my friend!
Ram

As usual, a great shot!
really detailed, well composed and managed with all the 4 eyes with a good spark.
Nice use of the flash light.

Andrea

bonjour jitti
avec une telle qualité d'image j'ai pensé que de mettre l'araignée dans un sens plus conventionnel et de la redimmensionner serait bien.qu'en pense tu?

Hello Jitti,
I don't know if this is the same species as your previous post that you refer to but this is a fine capture, the flash showing the details well and providing a good contrasting BG. Nice presentation of this spider.
TFS and best wishes, Ivan

Hi Jitti,
Beautiful compo, with excellent detail and very good use of the flash. Personally I think the vertical framing works better in this case.

Hi, Jitti.
What a great macro. Tack sharp. Excellent pose. Good exposure. Have you thought about turning it 90 degrees.

Nice spider JC with pleasant point of view.

I like it a lot: composition, POV, sharpness, colors, DOF, focus, background, lighting, framing, notes.

I don't like it: nothing.

A simple and effective composition to show mainly the enormous eyes of the animal.
Thank you and greetings... Ricardo
