Metachrosis (aka “Whitewall”) Pictures

One of the interesting quirks of Brazilians as a subspecies is their tendency to “lose” the color on their sides late in the day, an effect many keepers refer to as “whitewalling.” Under this effect, the color of the sides fades to an almost ghostly white.

Following are two recent, and rather dramatic, examples of this behavior. For each, I show the snake as it usually looks during the day, and then a late-day shot with whitewalls.

Drake, Day


Drake, Night


Ghandi, Day


Ghandi, Night


As with so many things about these snakes, fascinating stuff!

Thank you looking,

Thats amazing, is it lighting or do the pigments themselves change?

Re: Metachrosis (aka “Whitewall”) Pictures

It is indeed a cool feature of this species, and (as sickvenom noted) caused by scale pigments rather than lighting.

Thanks for all the interest!

Re: Metachrosis (aka “Whitewall”) Pictures

oh wow, that's awesome! Why does that happen? Does it have something to do with how they live in the wild?

My best guess is thermoregulation. Dark during the day to absorb heat, light during the night to keep it.

as far as i know - yes. but there are other species that can change other colors. there's actually a 'chameleon' snake from borneo.

Uh no, yours do NOT do the same. The same would be yours changing to white, yours change to light lavender and light grey. Yours may change colors, but not to WHITE.
