Na druhou stranu, mu\u0161\u00ed o\u010di jsou obrovsk\u00e9, a tak vid\u00ed na v\u0161echny strany kolem, ani\u017e by se musela ot\u00e1\u010det. D\u00edky tomu je schopna tak\u00e9 hbit\u011b \u010delit \u00fatoku pred\u00e1tora. Mo\u017en\u00e1 v\u00e1s p\u0159ekvap\u00ed, \u017ee mouchy vid\u00ed barevn\u011b, jedinou barvu, kterou nerozli\u0161\u00ed, je \u010derven\u00e1.

D\u00e1le mouchy dok\u00e1\u017eou skv\u011ble vn\u00edmat pohyb vzduchu.

Jak je mo\u017en\u00e9, \u017ee na mouchy nefunguje gravitace?

V\u0161echny plochy, po kter\u00fdch se mouchy pohybuj\u00ed, nejsou dokonale hladk\u00e9 a pr\u00e1v\u011b o tyto pro n\u00e1s nepatrn\u00e9 nerovnosti se mouchy sv\u00fdmi dr\u00e1pky op\u00edraj\u00ed.
