An uncommon striped pattern on McDowell's Carpet Python.By Dick and Patti Bartlett

Excluding the Green Tree, Amethystine and Oenpelli pythons, Australia is home to 3 species and 6 subspecies of heavy bodied, moderately sized (to about 8 feet/ 2- 1/3 meters) Carpet Pythons.

• Morelia bredli, Centralian or Bredl’s Carpet Python
  
• Morelia carinata, Rough-scaled Python
  
• Morelia spilota, Diamond Python and Carpet Python
  
  
  • M. s. cheneyi, Tableland Carpet Python
    
  • M. s. imbricata, Southern Carpet Python
    
  • M. s. mcdowelli, McDowell’s Carpet Python
    
  • M. s. metcalfi, Interior Carpet Python
    
  • M. s. spilota, Diamond Python
    
  • M. s. variegata, Northern Carpet Python
    

Except for the southeasterly most member, the one that is usually referred to as the Diamond Python, the carpet pythons are often referred to simply as Carpet Snakes by Australians. All are constrictors, all are nonvenomous, all are capable of biting, but their readiness to do so varies individually. All are accomplished climbers but may be found terrestrially in habitats as diverse as gardens, attics, or the remote outback. All are oviparous, reproducing by egg clutches that are protected by the female. All feed primarily on small mammals and birds.

All (except the Diamond Python which is black with a variable but often speckled pattern of white or cream) are colored in various shades of yellowish, cream or tan with a darker pattern. But sometimes the dark color prevails, and the light markings are reduced in size or number. Subspecies may interbreed where their ranges abut or overlap. The resulting hatchlings may be patterned non-typically. Encompassing all species and suggested subspecies the ranges include southern Western Australia, then hops to eastern South Australia and northward well into western Queensland, then throughout most of New South Wales and northward in the coastal forests and plateaus to Cape York. Then after another break in range it may again be found in northern Northern Territory westward to newest Australia. Bredl’s Python, seen as a full species by some and as a subspecies of the carpet python by others, seems more arboreal and ranges widely in southwest Northern Territory. The uncommon Rough-scaled Python is found in northwest Kimberly Region of Western Australia.

This is a typical Green Tree Python.

Long the only species in the monotypic genus, Chondropython, the green tree python has now been lumped with the diamond/carpet pythons in the genus Morelia where it remains despite nomenclatural controversy. Hobbyists still often refer to this snake by the shortened name of "Chondro." The species name is viridis, this meaning green. And this name fits the vast majority of the adults well, for almost all adults are green (occasional occurrences of yellow, blue, or albino adults have been verified) with or occasionally without white vertebral markings. But for the hatchlings it is a misnomer, for by locale they vary from bright yellow to a rich maroon-brown with reddish-brown or white highlights. These snakes are adult at 4 ½ to 5 ½ feet. The head is large, the neck slender, and the body laterally compressed.

Whether juvenile or adult, this is a beautiful snake. Adult coloration is assumed at an age of about 9-12 months and a length of about ~20 inches. It is an oviparous species, laying from a half dozen to two dozen eggs. Incubation periods of 49 to 60 days have been mentioned.

The diet consists primarily of rodents and occasional lizards. Prey is killed by constriction.

This beautiful python is a rainforest inhabitant of northeastern Australia, the Papua and New Guinea mainland and many of the surrounding islands. Adults are considered snakes of closed canopy forest while hatchlings and juveniles seemingly prefer more open and sunny perches.

This snake is a herpetocultural favorite and is bred extensively in captivity.
