Antarctic Anaconda is a combination of the incomplete dominant antarctic mutation and the heterozygous incomplete dominant anaconda mutation. The colours are a washed out grey that seems to resemble the axanthic colours, however they have a darker blue tint. There is a lack of head pattern present. After a few sheds, the colours lighten up. This gives the snake a contrasted look between the saddles and background. This morph is a new morph created by someone in China. The anaconda mutation creates a lack of pattern on the dorsal side of the snake.
