Native to Australia
, this endearing desert dwelling rodent
is known to drink its own urine
or in some cases eat its own crystallised urine. Well equipped for the outback environment, Tarrkawarras or "Desert Hopping Mice" as they are more commonly known by, have an elongated loop of henle within the kidneys in order to maintain its internal water balance.
Sadly, due to habitation loss and the introduction of pests, the species is becoming endangered. Average lifespan around seven years, average litter size 2-3 Tarrks.
