NORTHWESTERN (or DARWIN) CARPET PYTHON
Morelia spilota variegata
As most captive Northwestern Carpet Pythons come from the general area around Darwin, they are usually referred to as "Darwin Carpets" in the Pet trade, however the subspecies occurs in Western Australia and Queensland as well as a large area of Northern Territory and New Guinea.

Note that The Papuan Carpet Python which is sometimes referred to as Morelia spilota harrisoni is also currently Morelia spilota variegata

Map shows approximate Australian distribution of the Northwestern Carpet Python Morelia spilota variegata . This sub-species also occurs in New Guinea.

Many pythons look at their best when they first get their adult patterning (above).
The Northwestern Carpet Python Morelia spilota variegata in the 2 pictures below still has its hatchling coloration, typical for young Northwestern Carpet Pythons

Morelia spilota variegata Darwin or Northwestern Carpet Python
This Juvenile Northwestern Carpet Python Morelia spilota variegata has its body in a coil and its mouth open ready to strike. Note the strongly forked tongue present in all snakes and some lizards, and just behind that is the glottis (breathing tube) which can be extended forward when the snake is swallowing large food to allow it to continue feeding.

Notice what is left of the egg sac in the video above. It either gets absorbed or dries up after hatching.

ALBINO CARPET SNAKES

Morelia spilota variegata Darwin or Northwestern Carpet Python

All albino Carpet Snakes in captivity in Australia are descended from this subspecies, however it appears some have been crossed with other subspecies. Note that crossing subspecies in South Australia (and possibly some other states) is illegal. My understanding is that there were 2 original albino snakes. One of those was called Blondie who is probably the best known snake in Australia .The story of Blondie can be found here and pictures here.

If you cross an albino with a "normal" carpet python you will get no albino babies,
but all babies will be carrying the albino gene because the "normal" gene is dominant, whereas the albino gene is recessive.
A normal looking snake carrying the albino gene is called a Het (short for Heterozygous) normal x normal = all normal

het x normal = 1/4 het. 3/4 albino

het x het = 1/4 albino 1/2 het 1/4 normal

het x albino = 1/2 albino 1/2 het

albino x albino = all albino 

Note that when you cross a het with an albino there is no easy way of telling which snakes are normal and which ones are hets,
however the chance that a normal looking snake from this clutch is a het is 66% so the babies are called 66% hets.

A snake which known to definitely be a het is often called a 100% het to differentiate it from a 66% het.
