Even jumping spiders have personalities scientists have discovered. A "shy" individual will not make the same choices as a "bold" individual. This means that some individuals, because of their personality type, will capture more prey than others, and will therefore have a larger effect on local ecosystems.
Can jumping spiders see color?
Many spiders may also have a crude form of color vision, but for them it's usually based on green and ultraviolet light, which extends their vision into the deep violet end of the spectrum beyond what humans can see, and covers the blue and purple hues in between.

This characteristic and strictly nocturnal posture coupled with inactivity suggests that these salticids may be sleeping.

Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
