Southwestern Carpet Python

Morelia imbricata may attain a total length (tail included) of up to 2.3 m (7.5 ft), with a snout-to-vent length (SVL) of 2.0 m (6.6 ft). This species has a well defined neck and small scales across the head. Males may be up to 1.1 kg (2.4 lb) in weight, but females may be four times heavier when fully grown. Larger individuals have been reported as being 4 m (13 ft) in total length. Several other similar pythons occur in its range. The woma, Aspidites ramsayi, lacks the obvious neck of M. imbricata, and the western Stimson's python, Antaresia stimsoni stimsoni, has a higher number of ventral scales.

The preferred natural habitat of Morelia imbricata is coastal areas, woodland, heathland, and semiarid areas. It is often found in woodlands of Eucalypt and Banksia, or amongst grasses or low growing shrubs.

Morelia imbricata is discreet and slow moving, spending most of its time hidden, though occasionally it is seen attempting to cross roads. Typically this python is sedentary, but females in a survey at Garden Island were noted to be active most of the year. M. imbricata takes up residence in deep crevices or holes in limestone, on granite, in dense heath, and animal burrows.
