[NOTE: References #6 and #7 refer specifically to the eastern green lizard, Lacerta viridis, NOT the western green lizard. Due to their similarity and the debate regarding whether they should even be considered as fully separate species, I am willing to assume that the conclusions drawn here are applicable to both populations of the green lizard. (And in case you're interested - not that my opinion is worth a carrot - I don't consider viridis and bilineata to be separate species. Yes, there are important distinctions in the populations, but they CAN interbreed to produce fertile offspring, and this is sufficient evidence for a beginning taxonomic lumper like myself to consider them a single species. I've said this before, but such concepts as the species are only here to help us understand the natural world: they are discontinues categories used to make sense of a continuous phenomenon, being speciation. Then, they should have rigid definitions, or else they have no real meaning whatsoever. Species as groups or populations of potentially interbreeding organisms is the definition that is, across the board, the most useful, so that's the definition that I feel should be set. Western and eastern green lizards do not, then, fit the bill as separate species, differences notwithstanding.)]

Hey! I’m Fiona Shepley (this is my other account). I’m not sure if you remember me, but a few years ago I believe I argued with you on a few occasions, trying to tell you that heat lamps are bad for leopard geckos. Just wanted to say that I’ve significantly changed my views on leopard gecko husbandry since then. It’s awesome that you give your reptiles setups that are as natural as possible. Keep up the great work!
I don’t remember specifics - people disagree with me about all sorts all the time, so I tend to forget the names!
Thank you - good to hear that you’re improving your husbandry. We must all of us be doing so, always!
These are absolutely my favourite of your species whenever I watch your videos. They seem so active and interesting to watch.
I too am enamoured with them!
Fantastic video Joe! We even learnt something from it which is always great.
Thank you, great to hear!
Congrats on your new additions! They're native here in the channel islands, gorgeous creatures and a beaut of a set up well done.
Thank you, Lianne! I take it you’re from the Channel Islands, then? It must be brilliant seeing lizards like these around where you live!
@@JTBReptiles Yep, English but living in the Channel Islands now, I've seen them a couple of times so far but you've pretty much nailed their habitat!
You're making me want lacertids now!! LOL
Wonderful video, love those animals! Cheers!
Thank you! They are truly a brilliant species!
Watched this video again. Top notch mate.
Thanks mate, glad you like it still!
Maybe I’m just slow...
but did you get one or are you cohabing them?
Correct, I am cohabbing!
Interesting plant selection. I'm unfamiliar with most of them, I believe. I wish you had talked about them.
What kind of plants do you have in your enclosure? Interesting Video!
I have an azalea, a dichondra, some English ivy, some Kenilworth ivy, a black currant bush, a dead lavender, a common dog violet, and three sempervivia.
When you first wanted another reptile you said you wanted a tropical species. What were you originally trying to get for this enclosure?
Well remembered! I was going to get a Von Höhnel’s chameleon, Trioceros hoehnelii. Before that I’d wanted lacertids, so I swung straight back to them when the chameleon plan fell through.
This is awesome!!! Can you maybe do a video all about setting up and going through Leopard Gecko brumation please
Thanks! I won’t get chance this year - if it is to be a proper video, I need to be able to document the entire process, and I can’t do that before it’s actually been and gone. I only facilitated hibernation in the one leopard gecko I had at the time for the first time last winter, so back then I did not record anything. I did, however, record stuff for a bearded dragon hibernation video which will be produced shortly.
@@JTBReptilesI will look for the breaded dragon vid :) and look forward to all you new vids as well :)
Good vid. In minute 2:39 did you notice the ticks on the lizard behind his front leg? I hope its a picture of a wild animal.
Thanks! Yes, all the photos are taken from Google. It appears that ticks are a common parasite on these lizards in the wild - in almost every image of an otherwise healthy green lizard, you can see at least one tick buried behind the forelimb.
have u seen the melanistic lacerta? I was interested in getting a pair and do some breeding before breeding my tegu's (if i am successful).
Very pretty lizards :)
Yes, melanism is an apparently common trait in European eyed lizards. Whether it is present in other lacertas I do not know. Personally I prefer the blue/green “normals”, but I know many people like the black ones!
Brilliant video,,can't find any for sale in UK or price,,any contacts thanx,,👍👍
Cool vid mate. For interests' sake, who guessed correctly first? IMO, viridis and bilineata are the same species, just different subspecies.
I think you said “either green lizards or jewelled lacerta” first, so you’re the winner if I remember correctly!
See my discourse in the video description regarding species status 😉
Yes, yay, that was me! OK, so you too believe them to be the same species. Well, I can't wait for whatever you have next!
It’ll be a while yet, but I might have some ideas already... Brace yourself for next summer!
@@kodavulpedrius6712 We doubt that they are the same species, a lot of genetic differences. If they were the same species, the whole genus would have to be revised.
I hold them as the same species. We could do with sitting down and having a conflab about this, it’s an interesting topic 😂
our pet store right now has one on sale, but the color is dark and dull, not green at all. Not sure why.
