This species is found in Southern SA. They are mainly found on or very close to beaches, where they dig short, spiralling burrows on the dunes. This species grows to 85mm in body length and can be quite defensive, as shown in the photograph, when disturbed. They should be kept on sand and coco-peat to a ratio of about 60s:40p with enough depth to burrow, keep slightly moist or use a false bottom system, but for this species false bottoms are optional. U. novaehollandiae from WA tend to be darker in colour or with a prominent two-toned appearance, while those from SA are more light in colouration. While the photo doesn’t show it well, the ‘head’ and arms of this species are very dark brown to black while the rest of the animal is light brown.
