Female adders commonly reproduce once every two years. This might extend to once every three years if the climatic conditions are not favorable or if the seasons are short. Some subspecies of adders are known to reproduce once a year as well. The male tracks the scent of females. If there is a competition between males for mating, both males will try to chase each other away or enter into combat resulting in the ‘adder dance’. The male that manages to push the other one down or the last one standing wins the combat and gets to mate. The winning male and female mate and stay together for a couple of days. Young adders are hatched within the female and are generally 5.5-9.1 in (14-23.1 cm) in length including their tail.
What is their conservation status?

Adders have one of the most detailed venom delivery mechanisms. They have the potential to deliver venom deep into their prey’s tissues, making them extremely effective. Though their venom has enough poison to kill a human, there are only a few cases of deaths reported due to adder bites. This is a similar story when it comes to dogs. It is very rare that an adder snake bite kills a dog. This could be because of their shy nature. Adders tend to hide from humans and other domestic animals.
