The species Varanus gouldii is the most
widespread and abundant goanna found throughout most of the mainland in
Known as the Sand Goanna or Gould's Goanna, there are two sub species:
- V g flavirufus occupies the sandy desert region, and
is usually paler and generally redder;
- V g gouldii occurs over the remaining
regions of Australia;
with both foraging widely over dry open habitats.
In the northern and western part of Australia, the Sand Goanna is active
throughout the year, whilst in the south it is inactive during the cooler
months. Goannas are good at climbing trees and are also good swimmers.
