What does an adder look like?<\/h2>\n
Adders are quite small snakes<\/a>, the browner females rarely growing over 70 cm in length, with the more silver males somewhat smaller.<\/p>\n
Both sexes have the distinctive, dark zig-zag pattern down the back, with eyes of flame and a pupil that is vertically split. Some individuals may be melanistic, a darkening of the skin, a trait that might leave them more conspicuous to predators.<\/p>\n
Dogs, who tend to investigate with their nose, are prone to adder bites, but the amount of venom delivered is rarely fatal. Medical treatment should be sort if dog or owner is bitten, but we should cherish the adder and respect rather than fear it.<\/p>\n
