A work in progress: the pied stickler

It has been a while since I last posted something here. There were multiple reasons for that: the realisation that there are more than enough paintings for The Book lessened my enthusiasm to start new Furaha paintings. An interesting side effect of that is that I started painting a series of paintings completely unrelated to speculative biology, which was refreshing. So much so, in fact, that having finished three such paintings I became eager to do some more Furahan creatures.

Another factor is that the number of views and replies has been fairly low lately. Is a blog like this one too old-fashioned, or perhaps too complex? No longer interesting? Or is it too difficult to leave a reply? I thought so when I wanted to write something on someone else's blog. Ideas and thoughts are welcome.

Anyway, here is a detail of a work in progress showing a 'pied stickler' (Perfixor artifex). The name means 'cunning impaler'. A part of the accompanying text follows.

Katarzyna Altanero, who devoted her life to the study of hexapod carnivores, described sticklers as ‘prototypical gregarious piluferentic centauraptors’. This statement shows that doctissimus Altanero was one of those people who, once they have learned something, think that people are born with that knowledge already in place. But the cumbersome jargon is correct. 

'Centauraptors’
These animals are obviously hexapods, but they have freed their front legs from all locomotion duties, a principle known on Furaha as ‘centaurism’. Here, the limbs have become weapons.  
Centaurism probably involves very quick evolution. The front limbs, liberated from walking, were free to quickly evolve suitable shapes for their new roles. At the same time the balance and locomotion of the animal changed drastically. The front part of the trunk became shorter and was tilted upwards, while the former middle legs increased in size and moved forwards.  
   These changes must have evolved hand in hand with specialisation to a specific way of catching prey. For instance, predators relying on speed should not carry massive heavy clubs, and those aiming to bring down armoured prey must have adequate weaponry and need only be faster than their prey. Scavenging centauraptors can be slow , allowing some of the heaviest weaponry of all.   

‘Piluferentic’
Centauraptor weapons betray an interesting array of forms. Some are pure clubs, others function only as ‘pointy end’ weapons, and in yet others the limb has more than one purpose. The limb type known as ‘axes’ have a sharp edge on the underside, useful to hack open a carcass, but the same weapon usually has a heavy bulge too, allowing it to double as a club to knock prey off their feet or to bludgeon the prey's head, blinding it.
   The stickler’s weapons are no exception to this ‘Swiss army knife’ approach. While its weapon is primarily shaped like a club, the former foot has become a sharp protrusion that can be swung into action. This sting explains the word ‘piluferens’, meaning 'lance carrying’.   

‘Gregarious’
As the word suggests, sticklers live in groups. In this species’ case, tasks differ between group members, allowing a fairly complex society that must run on advanced cognitive capacity. Do not underestimate sticklers; one may appear to study you with open curiosity, but its pack members may well be behind you, on their way to encircle you. They cannot digest humans but that makes little difference to the human involved.

I'm glad you enjoyed making more art - thats always good.

As for me, I haven't posted here much lately, because I wasn't sure if the replies section of the previous blog post (about if prehistoric animals had kept evolving) was still being read by you, so I opted to wait for your return with a new post.

The new centaur is quite nice. I think this is the first "swiss army knife" type of Furahan centaur I've seen...all the prior centaurs I can remember on this site, they were specialists - some for clubbing, some for stabbing, and long ago, I have a vague memory of a net-handed one peeking out of a burrow.

You always make brilliant work, and you always explain them very very well. Kudos! And thank you for making such great animals.

Great name!

Keenir/Anthony: thank you. The change form specialist predators to 'Swiss raptors' came about when I looked again at the zigzag pattern I had chosen for Furahan hexapods. The legs start with the topmost segment pointing backwards, which turned out to be easy to modify into a foldable club or spear. When I mapped the segments, I found that three segments is quite enough for a club or spear, leaving the foot to... well, either wither away or be turned in an accessory.

Artifexian: I am not surprised at all that you like the name! I choose names using a Latin dictionary, usually a Lexilogos one. Here is the link: http://www.latin-dictionary.net/search/latin/artifex

Artifex; can be noun as well as an adjective; I used the second meaning (cunning) for the adjective, but suppose that you prefer other meanings, such as skilled and creative ;-)
Impressive worldbuilding, by the way. I get the impression that quite a few worldbuilders also like conlangs.

Keavan said...

I personally find this blog as interesting as ever, but I see what you mean about declining engagement. I've been a fairly longtime lurker, but I think I started occasionally commenting after the most recent official hiatus, because it was a shame more people weren't.

Sadly, I do think the age of the personal site or blog is likely coming to an end, with the various social medias being a far more convenient way of following a given person, topic, etc. Speculative evolution seems to be having something of a resurgence at the moment, with readings of All Tomorrows and a specevo project by Biblaridion both raising a lot of new interest on YouTube.

On a related note, Artifexian, are you the Artifexian of "Goodmorning interwebs, let's worldbuild" YouTube fame?

Keenir said...

I don't think social medias has anything to do with it, actually.

If my memory is accurate (and it often isn't), most of the people who currently post replies in this blog - and a lot of the ones who used to post replies in this blog - have their own speculative evolution websites...and some of the latter have retired from the SpecEvo field since they last posted.

pjamesstuart said...

A lot of bloggers are moving towards newletters like Substack.

Sigmund Nastrazzurro said...

Keavan: you are probably right.

Keenis/Anthony: I would hope that my blog doesn't only attract people with their own projects. It's is very nice to have those around, but I would like others to have a look to.

pjamesstuart: I'll look into that.

Abbydon said...

Speculative evolution is clearly a niche interest, though it is a subset of the wider subject of worldbuilding. If Reddit is anything to go by (which is a bit of a dodgy assumption) then the majority of people interested in worldbuilding mostly want to see the final product rather than discuss the process of achieving it. Perhaps that preference is just becoming more common over time?

Maybe you just need to advertise the art more widely, though that probably means interacting with social media more...

Sigmund Nastrazzurro said...

Abbydon: Some people who do a lot of explaining on YouTube attract lots of attention, so my guess is that people want to learn about the process as much as they used to. My next guess is that the form I use attracts fewer people over time. Too much reading and perhaps too academic?

You are probably right about social media, but I cannot say I like the prospect much...

Petr said...

This was a really awesome glimpse into the world of Furaha! Thank you for sharing!
I'm really glad you've found new ways to enjoy making new art as well!

Sigmund Nastrazzurro said...

Petr: thank you!

Keenir said...

Been thinking...(sorry)...
One of the advantages of having a website, as Furaha does, is that it can and does outlast the other forms of media sites. (you've already survived the end of yahoo, egroups, geocities, and, for the most part, livejournal; about half of the spec folks i knew on DeviantArt are gone)

...but even with a lot of forums having shut down one way or another, there are enough other sites - such as Reddit and Discord - that its entirely possible that any spec audience is spread farther/further and thinner than they might have been once upon a time.

A lot of spec projects have been featured on youtube channels like Thought_Potato and Curious_Archive (not sure if space is there), but lately, they've been showing mostly projects that are eitehr available to buy in book form, or are on Patreon and are being made into books. Maybe an episode of either channel looking at Furaha, might help with your The Book?

Just thinking aloud. I think I need sleep. :)

Idle Speculation said...

The club-spear setup reminds me of mantis shrimp. In the more famed club-clawed forms the sharp point is folded up against the previous segment to form the club’s head. I can’t help but think this is deliberate…

Sigmund Nastrazzurro said...

Keenir: I'm thinking about the options...

Idle: Well, the first centaur-like Furahan predators were definitely and consciously based on mantis shrimps, although I later only read more about their eyes, not their legs. But the overall resemblance is therefore indeed deliberate, on my part anyway (I am not sure about the mantis shrimps)

Idle Speculation said...

Also, would you be interested in looking into the Alien Biospheres YouTube series by the channel Biblaridion? It’s fairly rigorous and plays around with some interesting ideas like centaurised limbs opposing against trucks to create a second pair of jaws.

I meant tusks

Sigmund Nastrazzurro said...

Idle: I know Biblaridion's project. We exchanged emails and met in person at last year's TetZooCon in London. I had earlier even made a few animations of his landscapes with Vue Infinite. The ones that had only plants in them looked well enough, but it would have been much nicer to be able to do the animals too. He had 3D models of some of the animals, and after some troubles I could import them, but I could not 'paint' them properly, so they looked unnatural and stiff. I do not think he ever used the animations, which is fine.
I mostly stopped discussing other people's projects for various reasons: speculative biology is no longer a 'threatened species', many projects do quite well without my help, and I should also spend more time working on Furaha... But I may change my opinion.

Keenir said...

On the contrary, I'd be quite very reassured to know that, in the wake of my life, I wasn't poisoning the ecosystem or anything in it.

contemplative potato said...

I would be very sad to see this blog go! I've followed it(though anonymously) for a couple years now, pretty sure, and it's been very helpful in my own speculative biology projects. I find your advice and posts very useful.
If you do continue posting, then maybe I'd recommend setting up an alternative account on somewhere like Reddit or YouTube? You could keep the blog, but promote it with a few posts so people are aware. Many specevo enthusiasts know and love this blog, it might just be a problem of the new people who aren't fully familiar with the genre not knowing.

Sigmund Nastrazzurro said...

contemplative: As I wrote before, I do not plan to stop the blog, so for the foreseeable future it will stay in business. I may indeed make attempts to attract more attention though social media, although I am generally not a fan of social media.

Spugpow said...

I still read the blog, and actually have gotten back into the habit of reading blogs in general with the rise of Substack and the decline of Twitter. I also hate the consolidation of the internet into 4 or 5 giant social media companies. Like a biological ecosystem, an internet made up of a diversity of platforms and self-hosted websites is both richer and more resilient in the long term in my opinion.

We've seen a lot of front-limb centaurism for predators, but I wonder if hind-limb centaurism for prey might be almost as common? Kicking with the hind limbs seems to be a common defensive strategy against predators among ungulates on Earth, so it feels like some Furahan animals would have hind-limbs specialized for that purpose.

As for middle-limb centaurism, the first thing that comes to mind is adapting the middle limbs to be held splayed out while running for greater control over the center of gravity, serving the same purpose as a tightrope-walker's pole.

Sigmund Nastrazzurro said...

Spugpow: Very good ideas! I will think some more about both types of centaurism. I would like to include one or two of those ideas. I have always wondered why many mammals have such relatively poor defensive systems on their hind sides. Just think of scenes or wildebeest attacked by African painted dogs: the predators latch on to the wildebeest's largely undefended hind side.

An interesting aspect may be that posterior centaurism probably almost always will have a defensive purpose, in contrast to the almost always offensive one of anterior centaurism. Without weapons a predator cannot live for more than a few days, but prey animals should be able to live quite a while without defensive weaponry, provided they can also hide or run away. Does it pay to invest in defensive weaponry (and is high cost for too little gain the reason mammals' backsides are poorly defended?)

I also like the stability function of splayed middle legs. But sometimes stability is not good: I remember a documentary in which someone made students run while wearing a suit with a stiff tail sticking out to mimic bipedal dinosaurs. if I remember correctly, the students found it difficult to turn because of the tail. Then again, if you can swing the tail, you might get increased ability to turn. I wonder what happens when an animal with splayed middle legs would suddenly move of the middle legs forwards and the other backwards. Would it improve manoeuvrability?

Idle Speculation said...

I’ve seen a concept in which a hexapedal animal displaying forelimb centaurism reduces its hind legs to a degree to achieve a steeply sloping back. The difference in leg lengths then causes it to run solely on the middle limb pair, with the hindquarters shrinking and centaurizing to achieve a result that resembles a theropod dinosaur.

Credit goes to ComplicatedStarman from DeviantArt for this concept.

Idle Speculation said...

Completely unrelated, but how does the Stickler grow blue filaments? Is it a pigment or structural coloration?

Abbydon said...

> I have always wondered why many mammals have such relatively poor defensive systems on their hind sides.

I would assume that is influenced by the fact that, simplistically, they only need to outrun the slowest member of the herd and not the predator. Incremental improvements to running would probably be beneficial but incremental improvements to defensive capability might just make that animal more likely to be the slowest and therefore become dinner.

Of course, defensive capabilities have evolved before, so clearly it is possible.

Sigmund Nastrazzurro said...

Idle speculation: the Stickler's blue colour is based on pigments, but the Swobbler's purple plumes rely on structural effects. I saw no reason to copy the very sober an limited range of Earth's mammals. Hexapods can in principle have any colour. I haven't yet explored that range much, though. I probably should include one or two beasts with riotous colours. There are whole forests with primarily red plants on Furaha, so red can be a camouflage colour there.

Sockmonkey said...

I would expect centauroids to have much shorter necks, as the issue of reach is solved by the forelimbs. Why have your face out there in striking range when you don't have to?

Sigmund Nastrazzurro said...

Sockmonkey: good point, but animals still have to be able to reach the ground in order to drink or feed from the ground. With necks like they have, they can choose to keep the head near the body or extend it.

Sockmonkey said...

Good point about the drinking. You need a neck or something like a proboscis to get away with being neckless. As for food, the forelimbs might be agile enough to being food to the mouth like a glorified fork.

Sock Monkey: ... or a Swiss army knife
