Most wanted snake to see in the wild: Gaboon Adder! 

After more than 20 years of wanting to see a wild Gaboon Adder, the wish was granted. Seen recently in St Lucia on South Africa's north-east coast. This is a stunning snake, superbly patterned to blend in with the leaf litter on the forest floor, from where it ambushes prey such as rodents, hares, terrestrial birds, toads etc. Awesome stuff indeed!
