Anyone done any work on the genetics of those morphs Jonno?

Hey mate,
Scott Keogh was doing some research into Pseudonaja as a whole, but I am unsure what has actually been published. No doubt some morphs aren't found in certain areas but I do know that there can be an incredible variance of colourations and patterns within a single locality, and often within a single clutch of juveniles. For instance, the two most common colourations (possibly the only...?) of Western Brown in Alice Springs are the Black Headed morph and the "pale brown with thin band/speckling on the nape" morph like the one from Katherine that I posted a photo of.

Another interesting point is that nearly all Western Browns have some sort of marking on the back of their neck, or "nape", hence their specific name of "nuchalis". Some have a distinct thick black band, others have a small bit of speckling like in the photo of the one from Mildura, and some have a black head the extends down to their neck, but nearly all will have that marking. In fact I don't think I have ever seen one without some sort of marking, but I'm hesitant to say they they will definitely have the marking as my experience with wild Western Browns is only from half a dozen or so distinct localities and they are one of the most widespread elapids in Australia, occuring in every mainland state and territory apart from the ACT.

Have a good look at the head......the rostral scale on the nose end of the head...it's like a shield that curves over the top of the snout......pretty typical for Western Browns.
Its nice to see some photos of all the different colour morphs. I would agree with Johno in that all the Western Browns I have seen have some type of black marking on the nape....even if it is just a single scale. The inside of their mouths are also black if you care to look that closely!

I'd rather not, if someone did that to me they get knocked out.
