[Fangs]

No you got it in a nutshell Oz,
As far as ism's go I wasnt trying to get into that but merely trying to point out that these particular snakes have adapted over a relatively short period of time.
As far as feeding time goes they feed only for a short period of time per year.ie:the mutton bird breeding season.they are also darker in colour apparently to catch more heat from the sun to speed up their metabolism so they can gorge on even more chicks.
cheers
