Monitor musings, varanid variables, goannasaurian goings-on… it’s about monitor lizards

Current version of the monitor montage. Image by Darren Naish.

There’s been a bit of a monitor lizard thing going on here for the past few months: articles have covered Australian goannas, the Komodo dragon Varanus komodoensis, Dumeril’s monitor and Timor and Peachthroat monitors, and the ‘prasinoid’ tree monitors. In ‘spare’ time, I’ve been working on the montage you see here, designed to depict a [...]

“Lean, green and rarely seen”: enthralling prasinoid tree monitors

A tree monitor montage, images by Darren Naish.

I said in the previous Tet Zoo article on monitor lizards that I really wanted to cover the prasinoids; that is, the arboreal tree monitors of New Guinea, Cape York Peninsula and various of the islands surrounding these areas. So, let’s get to it. Tree monitors or prasinoids, also termed the Varanus prasinus species group, [...]

Obscure and attractive monitor lizards to know and love

Varanid portraits.

Everybody loves monitor lizards, or varanids. And there is so much to learn about, and to appreciate, in these remarkable, charismatic, complex, sophisticated lizards that scientists across many disciplines are being encouraged to study them and – lo – to make remarkable discoveries. In recent months we’ve seen the discovery of a mammal-like rate of [...]

Welcome to the Squamozoic!

When the Mesozoic ended, it was inevitable that the lizards, snakes and amphisbaenians – the squamates – would inherit the Earth. For the last 65 million years, the world has been so dominated by squamates that we term this stage in the planet’s history the Squamozoic. What is life like, today, on Squamozoic Earth? Purely [...]

Goanna-eating goannas: an evolutionary story of intraguild predation, dwarfism, gigantism, copious walking and reckless thermoregulation

Me and monitors go way back - these portraits were drawn over 10 years ago. Top to bottom: Mertens' water monitor (V. mertensi), Crocodile monitor (V. salvadorii), Green tree monitor (V. prasinus), Bengal monitor (V. bengalensis). Or, I think that's right.. I've lost the labels.

It’s well known that monitor lizards (or varanids) sometimes practise cannibalism (that is, predation within their own species), and it should be no surprise to learn that big monitor species sometimes (or even often) prey on and eat smaller ones. The phenomenon whereby predators predate on other, typically smaller, predators is termed intraguild predation, and [...]
