Synonyms[2]

The blue-tailed monitor, blue-tailed tree monitor or Kalabeck's monitor[1] (Varanus doreanus),[2] is a monitor lizard of the Varanidae family. It belongs to the indicus group of the subgenus Euprepiosaurus. Varanus doreanus has not yet been evaluated by the IUCN.

Subspecies[edit]

Two subspecies have been described: [3]

  • V. d. doreanus (Meyer, 1874)
  • V. d. finschi (Bohme, Horn & Zeigler, 1994)

The latter has since been elevated to full-species status as Varanus finschi. [2]

Distribution[edit]

This species can be found throughout the Island of New Guinea, on the island of New Britain and in the Bismarck Archipelago. The blue-tailed monitor is also found in Australia on the tip of the Cape York Peninsula. [2]

Description[edit]

The blue-tailed monitor can reach a total length (including the tail) up to 135 cm. This lizard is basically greyish-blue in colour. The body is covered with round ocelli. The throat is whitish and strongly marbled. The tail shows clearly a double keel. The basic coloration of tail is light blue (hence the common name of this species), which is interrupted by black cross bands. In adults this color fades away. [1] Scales on its neck are smooth and oval. [1]

Biology[edit]

These lizards feed on large insects, mice, fish, and crabs.
