All of these statements are false. I have been in Iraq (Marine Corps, LCpl Brockman). The spider can run fast, but nowhere near 25kph. The only reason it will run towards you is to get in the shade. Some are capable of making a "hissing" or "buzzing sound". Scientists have proven that the spiders have no venom, nor do they inject any numbing agents. They lay their eggs in the sand, not in a camels belly. They are strictly predators to small creatures, such as mice and enjoy moths and scorpions.
