The Dampier Peninsula monitor or Dampier Peninsula goanna (Varanus sparnus ), described in 2014, is the smallest known species of monitor lizard, growing up to 16.3 grams with a length of almost 23 cm and a SVL (snout to vent length) of 116 mm. It is believed to live only on the Dampier Peninsula of the Kimberley region north of Broome and Derby in Western Australia. It is highly active, making it difficult to photograph in the wild. It has short legs, an elongate body, a reddish-brown back with widely scattered black spots and "a ridged, circular and short prehensile tail."
The smallest species of extant varanid.
Restricted to rocky habitat in the northwest of Western Australia.
