A Fully-grown female munnart with a bushy tail and robust body walks in a woodland area of the Ironhorse county, Washington, not just searching for food, but also Maintaining her territory. Its rounded, erect ears were about 8 cm (3.1 in) long and covered with short fur. Unusually, the munnart was able to open its jaws to an unusual extent: up to 98 degrees, which leds to them being the Closest relative of the Thylacine (Thylacinus ankiocephalus, an accurate statement Made by the scientist using DNA). Though noted as having a stiff and somewhat awkward gait, She could suprisingly run at speeds of 49 – 65 km/H without even being tired.

Locals have named her "Melisha" and the Camera crews who were observing him in a Lookout Tower. Melisha had two cubs (not referred as joeys) to take care of, named ronald and marina. Its yellow-brown coat featured 15 to 20 distinctive dark stripes across its back, rump and the base of its tail, which earned the animal the nickname "tiger". The stripes were more pronounced in younger specimens, fading as the animal got older. One of the stripes extended down the outside of the rear thigh. Its body hair was dense and soft, up to 15 mm (0.6 in) in length. Colouration varied from light fawn to a dark brown; the belly was cream-coloured. Munnarts, uniquely for marsupials, had largely cartilaginous epipubic bones with a highly reduced osseous element. This was once considered a synapomorphy with sparassodonts, though it is now thought that both groups reduced their epipubics independently.
