Black melanistic adder in Kent04/04/2011 21:02:52
April 2011. Wildlife Extra's designer, Ilian Velikov, is a herpetological ethusiast to say the least. His most recent field trip, to north east Kent, yielded this very unusual black adder. While they are seen occasionally around the UK, it is fantastic to see such a good photo of this rarety.
Melanism is caused by an increased amount of dark pigmentation in the skin or coat of the animal. It is the opposite of leucism.
Ilian also spotted a white, leucistic starling in East London a few months ago.
