The "Johnson Jumper" ("Phidippus johnsoni") spider is the first of its species to return from a mission into space and successfully readjust to life on Earth. Named "Nefertiti," the arachnid astronaut, or "Spidernaut," lived for 100 days aboard the International Space Station. Vetter RS, Barger DK (2002).

In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax. Unlike most arthropods, spiders have no extensor muscles in their limbs and instead extend them by hydraulic pressure. Hannum, C. & Miller, D.M. "Widow Spiders".

Retrieved 3 August 2009.The stomach in the cephalothorax acts as a pump that sends the food deeper into the digestive system. The midgut bears many digestive ceca, compartments with no other exit, that extract nutrients from the food; most are in the abdomen, which is dominated by the digestive system, but a few are found in the cephalothorax. [13] Females of the water spider Argyroneta aquatica build underwater "diving bell" webs that they fill with air and use for digesting prey, molting, mating and raising offspring. They live almost entirely within the bells, darting out to catch prey animals that touch the bell or the threads that anchor it. [57] A few spiders use the surfaces of lakes and ponds as "webs", detecting trapped insects by the vibrations that these cause while struggling. [13]

The Spidernaut's flight was the product of YouTube Space Lab, a worldwide science project and contest that invited students to submit two-minute videos suggesting science experiments that could be conducted by the astronauts on board the space station. Police said they were treating Parle's death as "unexplained" after he was seen to fall while crossing the road.Females lay up to 3,000 eggs in one or more silk egg sacs, [13] which maintain a fairly constant humidity level. [47] In some species, the females die afterwards, but females of other species protect the sacs by attaching them to their webs, hiding them in nests, carrying them in the chelicerae or attaching them to the spinnerets and dragging them along.

The visual acuity of some jumping spiders exceeds by a factor of ten that of dragonflies, which have by far the best vision among insects. [ citation needed] This acuity is achieved by a telephotographic series of lenses, a four-layer retina, and the ability to swivel the eyes and integrate images from different stages in the scan. [ citation needed] The downside is that the scanning and integrating processes are relatively slow. [22]
