Spencer's goanna (Varanus spenceri), also known commonly as Spencer's monitor, is a species of monitor lizard in the family Varanidae. The species is endemic to Australia.

Etymology[]

The specific name, spenceri, is in honor of English-Australian biologist Walter Baldwin Spencer.[2]

Geographic range[]

Varanus spenceri is found in eastern Northern Territory and northwestern Queensland, Australia.[3]

It is native to the Barkly Tableland.[citation needed]

Description[]

Varanus spenceri can grow to a total length (including tail) of up to 120 cm (47 in). Spencer's monitor is generally heavier than a similarly sized monitor of another species due to its "stockier" build. It has sharp claws which it uses for digging burrows.[citation needed]

Diet[]

Varanus spenceri eats anything it can find, including highly venomous snakes, small mammals, small lizards, eggs, and carrion (dead animals), and is able to digest anything it eats.[citation needed]

Defensive behavior[]

When threatened, V. spenceri hisses loudly, distends its throat and whips its aggressor with its muscular tail.[citation needed]

Habitat[]

The preferred natural habitat of V. spenceri is grassland.[1]

Living in black soil plains with no trees, Spencer's goanna is the only Australian monitor that does not readily climb, although juvenile animals will climb given the opportunity.[citation needed]

Reproduction[]

Clutch size of Spencer's monitor generally ranges between 11 and 30 eggs.[4]

Taxonomy[]

Varanus ingrami Boulenger, 1906, is an invalid name (a junior synonym) for this species.[3]
