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 g (0.57 oz) with a length of almost 23 cm (9.1 in) and a SVL of 116 mm (4.6 in). It is believed to live only on the Dampier Peninsula of the Kimberley region in northern Western Australia. It is highly active, making it difficult to observe or 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."
