#Australian lizard

[greenspace01]

this photo shows a blue-tongued skink in my backyard a couple of days ago. the lizard is about the length of my forearm, has dark grey stripes across its light grey back and tail, and I was lucky enough to get a pic of it flicking out its grey-blue tongue -- yay!

This is the first time I've posted on tumblr in years, literally. Aaaages!

I've been doing a lot of volunteer fieldwork with these guys recently so I thought I might as well do an infodump about them here.

The pygmy bluetongue skink (Tiliqua adelaidensis) is one of the most unique and unusual members of the Tiliqua genus, which includes the true bluetongues as well as the sleepy lizard/shingleback. However, the pygmy bluetongue actually lacks the blue tongue the group is named after, having a pink tongue instead! As its scientific name suggests, it is quite a range restricted species, being found only in open grasslands north of Adelaide, South Australia, as far north as Peterborough. Historically they ranged more extensively across the Adelaide Plains, as far south as Marion, but due to the destruction of suitable habitat they now occur no further south than Kapunda.

While most bluetongues are notable for their large size amongst skinks, with several species regularly exceeding 30 cm in length, the pygmy bluey lives up to its name by measuring a measly average of 9 cm long from snout to vent. This is actually still a fair size compared to the average skink, but it's miniscule by bluetongue standards. Even more notable than their size however are their habits, for they are the only species of lizard that is specialised to live exclusively in old spider burrows! The burrows of both trapdoor and wolf spiders are used, but trapdoor burrows are preferred in most instances.

Pygmy bluetongues spend the majority of their lives within these spider burrows, leaving only to defecate, seek out mates and disperse. The average length of time a lizard spends in a particular burrow is highly dependant on the individual - some are sedentary and spend many years within a single burrow, while others will move around fairly frequently. As well as places to shelter and raise their young (they have parental care, it's very cute), pygmy bluetongues also use the burrows as ambush sites, waiting at the top for suitable prey, usually a mid-sized arthropod, to stray close enough for them to quickly dart out and drag them into the depths.

but here's the ambusher

The chief natural predators of pygmy bluetongues are raptors and brown snakes, and sheltering in the burrow is the main defence against both of these threats. Their burrows are often wide enough for a brown snake to enter, but not wide enough for them to open their mouths in - this means all the brown snake usually gets by pursuing a sheltering pygmy is an angry lizard attacking its face, forcing it to retreat.

The lazy lifestyle of the burrow-stealing pygmy bluetongues is certainly unique, and also explains why they have been such an elusive species since they were first discovered by Western scientists in the 1860s. Rarely seen or collected, their habit of inhabiting spider burrows remained undiscovered for the longest time, and by the 1960s they had become so hard to find that they were believed to be extinct. That was until, in 1992, a pygmy bluetongue was found inside the stomach of a roadkill brown snake by amateur herpetologist Graham Armstrong, confirming their status as a Lazarus of the lizard world.

Our previous assumptions of extinction were fortunately premature, but the pygmy bluetongue skink is in serious trouble nonetheless. While they are able to live in a variety of different grassland types, both native and exotic, the extensive modification of their entire distribution through cereal cropping and urbanisation has led to their populations becoming very small and fragmented, giving them a ranking of Endangered on the IUCN Red List. Almost all of these populations are on private land (often grazed by sheep), which makes protecting and/or studying them particularly difficult and complex.

However, when it comes to future threats to the species, climate change is easily the most worrying. As Australia becomes ever hotter and drier, their small remaining distribution is likely to become largely unsuitable, threatening the existence of the entire species. To combat this, researchers are currently investigating the viability of translocating populations further south to areas with cooler climates, providing a safeguard if they do indeed disappear from their remaining natural distribution.

But how do you study a lizard that lives exclusively in small spider holes? Well, if you want to catch them, there's only one tool for the job - the humble fishing rod. Not any special fishing rod either, just a regular rod with a poor mealworm shoddily tied to the end. David Attenborough kindly demonstrates the technique in Life in Cold Blood, although in his case the lizard was steadfast in remaining in the burrow!

Fun Pygmy Fact #2 - Wooden artificial burrows purpose-made for pygmy blueys have proven effective, and the lizards inhabiting them even tend to be in better body condition than those in natural burrows!

What I think is going through Comet’s head at all times

[artwithteggy]

I have always loved lizards, and I currently have velvet Geckos and Suzy the baby bearded dragon. These guys inspired me to make a collection of tubby Australian lizards. This is Max the fat bearded dragon and Ash the dinky Blue tongue lizard. These 3d prints are new designs I've been working on this week. Max can swivel his head from side to side and Ash is just Ash.

Tomorrow is photoshoot day and then I will be posting to my Cults3d online store!

I have a feeling that this new album is going to be an all time favorite for me. It’s truly an amalgamation of everything I love so so much about this band. The group vocals and the way they all get a chance to sing lead (even Cavs!). Just how collaborative it all is and how you can just tell they had so much fun making it. Not to mention the two new singles are incredibly fun and catchy. And the vocals?? Joey’s especially. This is the most full and confident I’ve ever heard him sing on record.

And I’ve always loved that you can tell just from the music how much this band loves playing music together and it’s especially noticeable with these new songs. You’re not just listening to musicians play together you’re listening to a group of best friends having fun together and that just makes me so so happy,

Fuck I love this band so much.

The obscure australian children’s book series “The Mysterious World of Cosentino” got turned into a tv show. The only thing I remembered after I woke up was that Professor Camoflauge (the lizard) had an Indian accent.

here's my newest guy 0-3! he's a giant heath goanna that works as a high-speed rail! 6 legs for maximum mobility, a windowed belly for passenger confort and the snazziest uniform in the whole southwestern australian scrubforest, 0-3 is your best mean of transportation around!*

*(except between september to january, as it's its hibernating period)**

**(Heath goannas hibernte september to april. 0-3 is an early riser)

tell me what y'all think!

MULTIPLE people thought I was australian on that poll.... head in hands

Doing sleepy lizard fieldwork in the Mid Murray today involved bountiful encounters with goofy fellas as usual

This guy is somehow missing the keratin on most of his large tail scales, revealing the bony scutes (osteoderms) beneath. We’re not exactly sure how this occurred, hopefully he’s not scuffed up too bad, but it is quite cool to look at

Then there’s grumps over here, sucking on his pacifier. We named him Cupcake after his delightful personality

Cupcake is now getting clamped because he’s naughty and bit someone (actually just taking a measurement of head depth)

Polite gentleman patiently getting his tail measured (not a sleepy lizard, doesn’t want to be here)
