Greg Florens, a 23 year old amateur photographer from Sedgefield stumbled upon 2 Puff Adders mating while on a nature shoot on Cloud 9. He was using a Fuji digital camera for both the stills and video footage.

We have decided to upload the footage totally unedited as this footage is so rare that we do not want you to miss a thing.

An Internet search including www.youtube.com revealed some but yet meagre video content of Puff Adders engaging in a mating dance prior to mating. We look forward to more exciting footage and stills from this avid outdoor photographer.

To find out more about puff adders please read the excerpt from Wikipedia below:
The average size is about 1 m in length and very stout. Large specimens of 190 cm (75 in), weighing over 6.0 kg (13.2 lbs) and with a girth of 40 cm (16 in) have been reported. Specimens from Saudi Arabia are not as large, usually no more than 80 cm in length. Males are usually larger than females and have relatively longer tails.
This species is probably the most common and widespread snake in Africa. It is found in most of sub-Saharan Africa south to the Cape of Good Hope.

Females produce a pheromone to attract males, which engage in neck-wrestling combat dances. A female in Malindi was followed by seven males. They give birth to large numbers of offspring: litters of over 80 have been reported, while 50–60 is not unusual. Newborns are 12.5–17.5 cm in length. Very large specimens, particularly those from East Africa, give birth to the highest numbers of offspring. A Kenyan female in a Czech zoo gave birth to 156 young, the largest litter for any species of snake.

This species is responsible for more fatalities than any other African snake. This is due to a combination of factors, including its wide distribution, common occurrence, large size, potent venom that is produced in large amounts, long fangs that inject it deeply, their reliance on camouflage which makes these snakes reluctant to flee, their habit of basking by footpaths and sitting quietly when approached, and their willingness to bite.
