Jumping spiders have eight eyes, the two large ones in the center-and-front position (the anterior-median eyes, also referred to as "principal eyes":51) providing acute vision and housed in tubes in the head. The other six are secondary eyes, positioned along the sides of the carapace and acting mainly as movement detectors.:16 While other spiders can jump, salticids including M. inclemens are the only spiders with good vision,:521 and their main eyes are more acute in daylight than a cat's and 10 times more acute than a dragonfly's. The main eyes focus accurately on an object at distances from approximately 2 centimetres (0.79 in) to infinity,:51 and in practise can see up to about 75 centimetres (30 in).:53 In M. inclemens, the front row of secondary eyes is only slightly wider than the third, whose width is 75% of the width of the carapace at that point.:2
Like other arthropods, spiders have sensors, often modified setae (bristles), for smell, taste, touch and vibration, protruding through their cuticle ("skin").:532-533 Unlike insects, spiders and other chelicerates do not have antennae.

Famous quotes containing the word senses:
“When other helpers fail and comforts flee, when the senses decay and the mind moves in a narrower and narrower circle, when the grasshopper is a burden and the postman brings no letters, and even the Royal Family is no longer quite what it was, an obituary column stands fast.”
—Sylvia Townsend Warner (18931978)
“The doctrine of those who have denied that certainty could be attained at all, has some agreement with my way of proceeding at the first setting out; but they end in being infinitely separated and opposed. For the holders of that doctrine assert simply that nothing can be known; I also assert that not much can be known in nature by the way which is now in use. But then they go on to destroy the authority of the senses and understanding; whereas I proceed to devise helps for the same.”
—Francis Bacon (15601626)
“I have almost forgot the taste of fears.
The time has been, my senses would have cooled
To hear a night-shriek, and my fell of hair
Would at a dismal treatise rouse and stir
As life were int. I have supped full with horrors;
Direness, familiar to my slaughterous thoughts,
Cannot once start me.”
—William Shakespeare (15641616)
