Varanus zugorum, also known commonly as the silver monitor [3] or Zugs' monitor, [4] is a species of monitor lizard in the family Varanidae. The species is endemic to the island of Halmahera in the Moluccas, in Indonesia. [5]
The specific name, zugorum (genitive, plural), is in honor of American herpetologist George R. Zug and his wife Patricia. [2] [5] [6]
V. zugorum is only known with certainty from its type locality in the vicinity of Jailolo. [5] [2] [7] Reasonably reliable local eyewitness accounts exist from Akesahu (lower western side of Kao Bay) and Labi Labi (northeast Halmahera). [7]
Zugs' monitor was described from a juvenile museum specimen originally labeled as Varanus indicus . [2] [5] At least one or two specimens resembling the type specimen and generally agreed to represent this species have been imported at various times for the pet trade. Other than this however, the species is unknown. Its habits are unknown as it has not been observed in the wild and is rarely seen even by natives. [7]
V. zugorum is among the 25 “most wanted lost” species that are the focus of Re:wild's “Search for Lost Species” initiative. [4] The Biodiversity Group is currently working to find the Zug’s Monitor using EDNA and using a 3D scanning camera to avoid having to taxidermy the specimen. [8]
Based on the holotype, a juvenile that measures 150 mm (5.9 in) in snout–vent length and 360 mm (14.2 in) in total length, the background color of V. zugorum is a silver-greyish. The body and limbs are patternless save for scattered bluish scales. The tail is mostly patternless except for a dozen faint dark bands towards the tip. The underside is yellowish and unpatterned. The tongue is dark purplish with a pink base. [2]
Monitor lizards are lizards in the genus Varanus, the only extant genus in the family Varanidae. They are native to Africa, Asia, and Oceania, and one species is also found in the Americas as an invasive species. About 80 species are recognized.
The Asian water monitor is a large varanid lizard native to South and Southeast Asia. It is one of the most common monitor lizards in Asia, ranging from coastal northeast India, Bangladesh, Sri Lanka, mainland Southeast Asia, and southern China to Indonesian islands where it lives close to water. It is listed as Least Concern on the IUCN Red List. It was described by Laurenti in 1768 and is among the largest squamates in the world.
The black tree monitor or Beccari's monitor is a species of lizard in the family Varanidae. The species is a relatively small member of the family, growing to about 90–120 cm (35–47 in) in total length. V. beccarii is endemic to the Aru Islands off New Guinea, living in an arboreal habitat. The skin color of adults is completely black, to which one common name refers.
The mangrove monitor, mangrove goanna, or Western Pacific monitor lizard is a member of the monitor lizard family with a large distribution from northern Australia and New Guinea to the Moluccas and Solomon Islands. It grows to lengths of 3.5 to 4 ft.
The emerald tree monitor or green tree monitor, is a small to medium-sized arboreal monitor lizard. It is known for its unusual coloration, which consists of shades from green to turquoise, topped with dark, transversedorsal banding. This coloration helps camouflage it in its arboreal habitat. Its color also makes the emerald tree monitor highly prized in both the pet trade and zoos alike.
The golden-spotted tree monitor, also known commonly as the golden speckled tree monitor, is a species of monitor lizard in the family Varanidae. The species is endemic to Waigeo Island in Indonesia.
The peach-throated monitor, also known commonly as the Sepik monitor, is a species of monitor lizard in the family Varanidae. The species is native to New Guinea.
The turquoise monitor is a species of monitor lizards found in Indonesia. Specifically, it is found on Halmahera Island and in the Maluku Islands.
The Ceram mangrove monitor is a species of monitor lizards found in Indonesia. Specifically, it is found on some of the central Moluccan Islands including: Ambon, Seram, Obi, Buru, and Banda. On Ambon and probably on New Guinea V. cerambonensis occurs sympatrically with Varanus indicus. It is in the indicus species group of the subgenus Euprepiosaurus.
The blue-tailed monitor, blue-tailed tree monitor or Kalabeck's monitor, is a monitor lizard of the Varanidae family. It belongs to the V. doreanus group of the subgenus Euprepiosaurus.
Dumeril's monitor is a species of lizard in the family Varanidae. The species is endemic to Southeast Asia.
The sago monitor or torch monitor is a species of monitor lizards endemic to the Indonesian island of Sanana.
Finsch's monitor is a species of monitor lizard in the family Varanidae. The species is native to New Guinea and Australia.
The Rennell Island monitor is a species of monitor lizards found in the Solomon Islands archipelago. It is also known as the Hakoi Monitor. It belongs to the subgenus Euprepiosaurus along with the canopy goanna, the peach-throated monitor, Kalabeck's monitor, and others.
Varanus kordensis, the Biak tree monitor, is a member of the Varanidae family found on Biak Island in Indonesia. It is also known as the Kordo tree monitor. Long considered a subspecies of the emerald tree monitor, most authorities now treat it as a separate species.
Varanus macraei, the blue-spotted tree monitor or blue tree monitor, is a species of monitor lizard found on the island of Batanta in Indonesia. It is named after herpetologist Duncan R. MacRae, founder of the reptile park Rimba on Bali.
Varanus telenesetes, the mysterious tree monitor, is an enigmatic monitor lizard that may actually represent a colour faded specimen of the green tree monitor. The species was described based on a single specimen supposedly collected on Rossel Island in the Louisiade Archipelago of Papua New Guinea. However, later searches of this island have failed to turn up any specimens and native islanders deny ever seeing it. It is now believed that the original collection data was in error and that the species occurs on some other, currently unknown, island east of New Guinea.
Varanus rainerguentheri, also commonly known as Günther's mangrove monitor and Rainer Günther's monitor, is a species of lizard in the family Varanidae. The species is endemic to the Moluccas.
Varanus spinulosus, the Solomon Island spiny monitor, Isabel monitor, or spiny-neck monitor, is a species of monitor lizard. It is endemic to the Solomon Islands archipelago and is also known from Santa Isabel Island, San Jorge Island and Bourgainville Island.
The Yuwono monitor or tricolor monitor, also commonly known as the black-backed mangrove monitor or the black-backed monitor, is a species of monitor lizard in the blue-tailed monitor species complex. The tricolor monitor is endemic to the island of Halmahera, in the Maluku Islands, Indonesia.
