A typical Jumping Spider would have 2 big Anterior Median Eyes (AME) in the center of the face, with 2 smaller ones at the side of the face (A). 2 equally small ones (B) would be at the top the carapace to cover the rear vision and finally, a last pair just in front of them (C). Yes, total of 8 eyes. =D This is illustrated in #1 below.
The AMEs have high visual acuity but a very narrow field of vision. They are long and tubular, and can only have a narrow field of vision. It is able to look around by moving the retina within the carapace – that is why we can spot jumping spiders with colours of their AMEs changing. When the colour is at it’s darkest, the spider is looking straight at you.
#1 Position of the eyes of a Jumping Spider.
#2 The eyes (AME) of the jumping spider are most beautiful when captured straight on. Of course, this may be subjective, but it is my favorite angle. 🙂
#3 A wider view. If you could squint and look closer, you might see my hand in the reflection of the eyes.
#4 Cropped view of the above. See my fingers? I was trying to block the focusing light.
#4 Lovely details on the jumping spider
#5 Very colourful jumping spider (Siler sp.)
#6 Yet another cute fella
#7 From the looks of this picture, this Jumping Spider is not looking at the camera. Otherwise, the AMEs would be almost black.

#9 A broader head, but just as cute!
#10 Some have punk-like hairdos
#11 While others have a very black face, like this Pystira ephippigera
#12 Most of them tend to look up as you approach them
#13 They come in lots of beautiful colours too!
#14 Most are just as curious, like this Portia labiata
#15 Some look super duper adorable
#16 The hair on top of the carapace is almost always crooked. lol
#17 Some have really oversized jaws
#18 Some grow over 15mm long, like this Heavy Jumper
#19 Some have long, slender legs
#20 Some were found to be doing yoga
#21 And more often than not, they appear really shy. lol
