Tasmanian Devil (Sarcophilus harrisii) Fact Sheet: Physical Characteristics

Tasmanian Devil (Sarcophilus harrisii)

Physical Characteristics

Body measurements

Attribute Males Females
Body weight 8-14 kg (20-31 lb) 5-9 kg (10-20 lb)
Head-body length 652 mm (2.14 ft) 570 mm (1.9 ft)
Tail Length 258 mm (10.2 in) 244 mm (9.61 in)

General Appearance


  • A stocky meat-eating marsupial the size of a Boston terrier, with a long tail, short legs, and long whiskers
  • Described by Quammen (2008a) as having a "trundling" gait and an appearance somewhat like "an underfed bear cub"
  • Tasmanian devils are the largest carnivorous marsupials in the world today


  • Black fur marked by white on rump and chest
    • In their study of a wild population at Mt. Williams National Park, Tasmania, Pemberton & Renouf (1993) concluded that devils are not uniquely marked by their white patches
      • Up to 13% of the animals were entirely black
      • Devils could not be uniquely identified by white patches
      • White serves to orient devils to the front and rear of opponents during nighttime encounters

Sexual Dimorphism

  •  Males 15% larger than females (Jones 2008)

Other Physical and Physiological Characteristics

  • Four teats (Guiler 1970)
  • Pouch open to rear (Guiler 1970)
  • Have no "baby (deciduous) teeth" that are lost; original teeth are kept (Owen & Pemberton 2005)
  • Teeth, like those of hyaenas, are highly adapted for carnivorous diet (Jones 2003)
    • Very strong canine teeth with bite strength similar to maned wolf (Chrysocyon brachyurus) (Jones 1995)
  • Sharp, non-retractable claws for digging, holding prey, finding food (Owen & Pemberton 2005)
  • Four toes on ground on hind limb; five digits on forelimb (Owen & Pemberton 2005)
    • Have an extended foot pad, like all members of the dasyurid family, which covers the heel and wrist as well as digits (Jones 2003)
      • When standing, devils put weight on these pads
      • When walking, however, devils are digitigrade (up on their toes) (Jones 2003)
    • Can freely rotate hind and forelimbs inwards to enable tree climbing and prey grasping (Jones 2003)
  • Acute sense of smell, good even at 1 km (.6 mi) (Owen & Pemberton 2005)
  • Very long whiskers extending beyond shoulder width (Pocock 1926)
  • Wide ears are well-supplied with blood vessels (Eisenberg et al. 1975)
    • When agitated, ears become red
