Misumena vatia - The color change from white to yellow (depending on the color of the flowers on which the spider is hunting) takes between 10 and 25 days; the reverse about six days. Chrysso venusta has been observed to rapidly change its color when disturbed. Some spiders, including Cyrtophora cicatrosa, can change colour rapidly. [9]
Summer patterns are typically disruptively patterned combinations of shades of browns and greys, up to black, while winter patterns are dominated by white to match snowy landscapes. Among animals, variable snow camouflage is a type of seasonal polyphenism with a distinct winter plumage or pelage.
For example, the Arctic fox has a white coat in winter (containing little pigment), and a brown coat in summer (containing more pigment), an example of seasonal camouflage (a polyphenism). Many animals, including mammals , birds , and amphibians , are unable to synthesize most of the pigments that colour their fur or feathers, other than the ...

The ears are brownish with black tips and white or creamy borders. During the winter, the fur is almost entirely white, except for black eyelids and the blackened tips on the ears.
The color phases are genetically controlled. The dark phase results from a single dominant gene and the white phase is homozygous recessive. When choosing a mate, young birds will most often select a mate that resembles their parents' coloring. If the birds were hatched into a mixed pair, they will mate with either color phase.
The snowy owl is certainly one of the most unmistakable owls (or perhaps even animals) in the world. [7] [10] No other species attains the signature white stippled sparsely with black-brown color of these birds, a coloring which renders their bright yellow eyes all the more detectable, nor possesses their obvious extremely long feathering.
