Adder Snake CharacteristicsĪdders grow to measure around 90 centimetres in length, however, they are generally smaller, especially where the climate is cooler. Adders do this by hibernating between October and Spring, coming out into the open at different times each year depending on the weather conditions.

The distribution of these three snakes is quite wide with the Adder being spread all over mainland Britain, the grass snake generally keeping to the warmer regions just below Scotland and down to the South Coast and the smooth snake only found in the Southern Counties. The Adder and the Grass snake are the most common known snakes on the British Isles, however, the Smooth snake is only recognised by very few people. It does, however, support three types of native British snakes, the Adder, the Grass snake and the Smooth snake. Britain does not inhabit a great deal of reptiles which is mostly because of its cool, damp climate.
