Camel spider also called Wind scorpion, and Sun spider.

When I first saw one of these interesting animals arrive at my local reptile shop, I just had to go back and buy one, even though I was selfishly thinking of my photography, more than the animal, probably wild caught taken from its home.
The Camel spiders were just being unpacked and three had arrived the day before, so I chose the largest thinking that it would be fertile. I had the right set up at home even brought red desert sand thinking of the contrast for my photography, so I was shocked and saddened to see it dead the following morning. I had taken some photos of it the day I brought it, may be I should have let it settle first, I did notice it did not want any food and some of its legs were curled in. But I believe it was stress of the journey that killed it, as they are not long-lived and more fragile than Tarantulas.
The camel spider as you can see from my pictures had white patterns around its abdomen, and after it died I cut it open to revile my suspicions that the white patterns were indeed eggs, in fact there were over 50. Well I went back to my local reptile shop and I brought one of the smaller spiders they had left for half the price, as they would not guarantee for livestock, I told another Tarantula collector about the spiders and he brought the third from the shop.
Well this spider is much more lively than the first Spider I brought, very active, and always digging, watching this amuses me as it uses all its front legs at the same time to spread the sand away, well I felt sorry for it digging and not really getting any where, and then it started to dig under the Exo water dish. So for safety I thought it would be good idea to make it some tunnels, as once it created a large sand hill and was completely buried so I used a piece of plastic tubing , used for plumbing, with a 90 degree bend, the tubing is slightly narrower at the width end of the tank and wider for the length which is laid at the back of the tank, I then covered it in sand, the spider ran into it straight away, and blocked the narrow end, now any cricket or giant mealworm larvae or beetle that enters the tubing, don’t come back, and I can hear the crunch crunch of its pray being crushed by its powerful jaws It still digs but a lot less, than before. During the day the spiders enclosure has a higher temperature, and a lower temperature in the evenings when I lightly spray with water to increase the humidity to replicate a desert environment.     
Camel spiders although not a true spider, are a link between a spider and a scorpion, and are from a group called Solifugids, this Latin name means "flee from the sun" as they are mostly nocturnal, hiding in holes in the desert by day. They hunt for prey such as, insects, reptiles, small birds, and frogs. It said is said they chase people while making a screaming sound, in fact they are chasing a persons shadow, and if you fall over, it will burrow under you.

The Camel spider has been made more famous from armed forces stationed abroad, which over hundreds of years have found them fascinating creatures. You only have to see pictures and films posted on the web of theses animals, set up in oil barrels filled with sand, filming these spiders attacking each other or duels to the death with a scorpion. They can run up to 10 mph, which they can use, catch their prey. They have two pairs of powerful, sharp (Chelicerae) jaws to rip open there prey, and crush the hardest wing cases of beetles. There jaws are the first thing you notice as these look odd as they are vertically positioned in front, looking like a pair of pincers, which is different from most other Arachnids and insects. The jaws are not venomous but could be a risk from infection to a human. I know when moving the spider for my photography it faces and attacks any thing that moves, including me. Dead insects lay around its enclosure, and can feel it biting very hard on my paintbrush handle. One time while filming it just would not let go of my brush, and moved it into the air still clinging to the brush, glad it was not my finger.
The spider has two eyes positioned at the top of its head. It is also covered in long fine sensitive hairs, and probably helps detect vibrations and prey. There Pedipalps are very extended, which look like another set of legs, they act like a antennae when my spider is hiding inside its tubing, often it is just its Pedipalps sticking out, when any prey touches them the prey gets zapped with its jaws, hungry or not.
I think the Camel spider photographed on red sand, would not be out of place on a red Mars landscape, as it just looks so alien looking. They are well worth the effort, needed to keep these creatures in captivity, similar to keeping scorpions, just mind your fingers.
