[QUOTE="Joe, post: 10671, member: 38"] A mantis's compound eye is made up with thousands of ommatidums, all connected to the visual receptor center. Imagine a thousand telescopes attached to ur eye all facing in different directions to form a dome shape like the mantid's eye, looking like the cross section Johnald has, no matter with end u look at of each lens, they will all show a black dot because of each ommatidium leading stright to the visual receptor center, and since all these ommatidium are extremely small and can be seen through the human eye over a larger area, this makes you look through maybe hundreds at a time wich makes the black dot bigger. but being limited to looking through a little amount of ommatidium lenses directly because of the dome shaped eye, this limits the black dot's size. if the compound eye were completely flat and no angles at all, the black dot would cover the whole area because all the lenses would be facing u directly. All athropods have these type of compound eyes and have the same effect. Joe [/QUOTE]
