Feature Facts

• Many Bennett's wallaby bones found in Tasmanian caves; hunted by early humans
• Wild populations reintroduced to New Zealand
• Group dynamics very fluid
• Communicate using their ears, narrow set of vocalizations (growl, hiss, cough, cluck), and scent marking
• Reproduce efficiently; easily bred in managed care
• Young first emerge from pouch at about seven months old
• Adult males can be up to twice as large as females
• Like other macropods, develop and lose four sets of molar teeth over a lifetime; teeth wear down from eating tough plants
• Tasmanian Wolves and Marsupial Lions were Ice Age (Pleistocene Era) predators of this species
• Commercially harvested; ranchers and farmers sometimes perceive these wallabies as a threat to crops and sheep food supplies in pastures
