- Monitor lizards are currently classified under one genus (Varanus), but they are quite diverse. They also have several traits that enable them to perform better than most lizards, arguably most extant reptiles even. They are a relatively well studied group of animals and many keep them as pet, so let's learn about their biology.

More than I ever knew I wanted to know about Monitor Lizards and incredibly comprehensive. Thank you.
Appreciate this video- as someone who has been working with and keeping monitors (odatria specifically) for a couple of years now I find myself fascinated and always wanting to learn more.
Always love learning more about varanids.
Really liking your content dude. Chill vibes, good info, interesting relevant footage. I'm looking forward to seeing your channel grow, keep it up
excellent video. playful? fascinating.
Varanus really is an overlumped genus
Awesome video!
Outstanding content. Informative and entertaining, with a lot of great gags. Subbed. More herp content please :)
There will definitely be more herp contents in the future but i try to rotate between animal groups
great video
this rocks, im blessed
I am interested to learn what member of Empagusia is more related to Soterosaurus than to other Empagusia,
Thank you for this video it is a very informative and entertaining.
It's Varanus rudicollis (roughneck monitor).
Based on genetic analysis, they grouped together with V. salvator group.
You can read the full publication for free here
onlinelibrary.wiley.com/doi/10.1111/j.1096-0031.2001.tb00118.x
in terms of ecology they are the lizards equivalent of minks otters stoats and badgers.
I eat monitor lizards and they taste pretty 👍
What types of monitors have you kept and/or bred? I would looove to keep a green tree one day, or any of the tree monitors.
Oh, maybe you just studied them a lot formally
I never personally own a monitor myself, but i do took care of several individuals for years, mostly for educational purposes and research (not my research though).
Almost all of them are asian water monitors but with different subspecies
can you do beared dragons next ?
So you have a pretty good video. Just a few corrections on the info here and there. From a monitor keeper.
The Salvator water monitor is not the second largest lizard
They other bit is scientific names. You have a few mixed up. And a few other bits and bobs.
Do a little more research and keep the videos commin my guy. Can’t wait for more.
Could you please elaborate?
What do you think is the second largest?
Also, what scientific names got mixed up?
For length wise you have the
1 v. Salvadorii 12-14ft
2 v. Komodoensis 10ft
3 v. Giganteus 9ft
4 v. Varius 7-9ft
5 v. Salvator 7-9ft
(4 and 5 is a bit of a toss up because they are extremely close when looking at the Sumatrans to Lacie. I know a few Lacie breakers over here and I’ve held some longer than the Sumatran local v. Salvator. Taking weight aside just goin for length here I believe the order I put should be correct but I may be wrong.)
From my view and experience so far that’s is what I have seen and learned are the top 5 largest in length in that order.
W the scientific names it was the Argus monitor - v. Panoptes storr
Crocodile monitor - v. Salvadorii
It wasn’t as much as you got them wrong more so you used less common versions of the scientific name. Or you may be from what was popular at the time of your masters. Or looking at things from another side of the world. I’m just assuming there.
You also said some of the larger monitors tripod. When in fact the v. Panoptes storr is known for the tripodding . There are some other monitors in the mid range size like the v. Panopetus storr that stand on there hind legs to get a better view of what’s around and threat displays. But it’s usually the monitors in the 5 foot range.
And again I don’t say this to bash or be rude. I love your video and I am gonna share it w other nerds like myself whom love monitors. Haha
The reason I offer some help w some of the stuff is because I am the guy who captive bread v. Salvadorii in the US in 2021. And am currently working on the documentation and continuation of the project. You can look me up under Mr.SalvadoriiLLC.
I really would like to open up a good line of communication between us so we can talk better and more often. I’ll leave that one up to you. Tis ok with ether option you chose.
@thatdeadguy.666 Hey, thanks for taking the time to write such a long answer.
Don't worry, I didn't take it as you being rude or anything really, I'm actually curious because as you might've heard from the video, it's been so long since i follow the scientific progress on monitor lizards.
Regarding me saying salvator is the second largest, i consider "large" or "big" as something bulky and heavyweight. I am aware that salvadorii is the longest, as stated in my video, hence the second longest would be the komodo dragons. Of course it is my fault that i didn't clarify what i mean by "largest" in the video, so i apologize.
About the scientific name, i still don't understand what you mean unfortunately. I just recheck the video and i did write their name as Varanus salvadorii (16:53) and Varanus panoptes (21:30) in the video.
About my statement that the "larger monitors" are known to tripod, i guess it's confusing because i didn't specify what i meant by "larger" in this context. I don't mean the absolute size per se, i mean the group. That's why i talk about tripoding in the subgenus Varanus section of the video. You are correct that when we are talking about absolute size, individuals that reached larger sizes tend to not tripod.
I'll try to do better and specify more on what i meant in the future.
And of course, good luck on your project. Hope all went well.
