JUMPING SPIDER

This tiny fellow came visiting inside my house this morning.
Finding a welcome change in the subjects to shoot, I took a few macros of it. However, the house walls do not make good backgrounds and indoor light during the day is also dicey. I therefore used fill flash and only one result came out passable which I am posting today.
The image was shot vertically with the spider looking down at me with those curious eyes and I rotated the image for a better perspective. Hope you find it interesting.

The jumping spider 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. 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.

Habitat

Jumping spiders live in a variety of habitats. Tropical forests harbor the most species, but they are also found in temperate forests, scrub lands, deserts, the intertidal zone (in Malaysia), even mountains (one species is reported to have been the spider collected at the highest elevation, on the slopes of Mt. Everest.

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.
Colours and patterns vary widely. Several species of jumping spiders appear to mimic ants, beetles, or pseudoscorpions. Others may appear to be parts of grass stems, bumps on twigs, bark, part of a rock or even part of a sand surface.

Behaviour

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 spiders to jump without having large muscular legs like a grasshopper. The jumping spider can therefore jump 20 to 60 or even 80 times the length of their body. When a jumping spider is moving from place to place, and especially just before it jumps, 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.

Hello Sir, good compositon and still I think the eyes and the views could have been better. Ganesh

Hola Ram,
Excelente macro de esta pequeña araña saltarina, suelen ser muy esquivas y difíciles de fotografiar. Un cordial saludo

Hello Ram, I never heard of, or saw Jumping Spiders before I came to TN, but I now recognize that stance, and those shiny eyes, and you've captured it here in this shot of yours. This is one I need to watch for, I would love to add one of these guys to my collection. Your use of the fill flash gave you good definition up front with excellent detail on those front legs and his head.

Thanks, John

Hello Ram,
After a very long time I'm here again and it is nice to see your fantastic shots, again.

Very nice and clean image. Bravo my friend and TFS.
Greetings.

Hi Ram,

Excellent macro of this jumping spider, the detail is stunning, really like the side on POV, really nice work, all though I have to be honest I would be heading in the opposite direction really fast, all the best,

Cheers Rick :)

Hello Ram,

Beautiful picture of this Jumping spider. Excellent POV, good composition and very good focus. Light and colours are great too.
Cheers,
Mariki

Large frame:-) It makes him look smaller which is fine with me. Very nice Ram...with exception that I am not fond of these. The positive is that for some reason we do not have them here in the city. Plenty in the wilderness...good description. Fine ID'able image as well.
