I’m re-reading “Furry Logic”

https://www.furrylogicbook.com/

It’s a very interesting book and obviously I missed/forgot some of it since I last read it a couple of years ago. Anyway, the Komodo dragon stuff got interesting, so I sought out the paper where some people worked out how strong the skull is and how the dragon bites. It’s got a poor bite, but uses a twist and tear system, and in this way the skull does not need to be heavy. Quite a different mechanism from crocodiles. The researchers used some engineering thingies to work it out.

Some of you lot might also find it interesting.

Not to be confused with fuzzy logic.

> The Komodo dragon displays a unique hold and pull-feeding technique. Its delicate ‘space-frame’ skull morphology differs greatly from that apparent in most living large prey specialists and is suggestive of a high degree of optimization, wherein use of materials is minimized. Here, using high-resolution finite element modelling based on dissection and in vivo bite and pull data, we present results detailing the mechanical performance of the giant lizard’s skull. It applies minimal input from the jaw muscles when butchering prey. Instead it uses series of actions controlled by postcranial muscles. This remarkable reduction in stress in response to additional force is facilitated by both internal and external bone anatomy. Functional correlations obtained from these analyses also provide a solid basis for the interpretation of feeding ecology in extinct species, including dinosaurs and sabre-tooth cats, with which V. komodoensis shares various cranial and dental characteristics.

Yes. Very interesting. Many dinosaurs have very lightweight skulls. Not so sure about sabre toothed cats, but have never managed to understand how they open their mouths wide enough to bite.

So we have a Komodo dragon at the zoo. And in our training reading it had as an interesting fact that They are prone to ramming large prey into their gullets by running at stuff to slam it down fast. A bit like the solo ads but with meat.

I’ve watched a video of a water monitor up in NT that had caught a large crayfish. It was having trouble trying to kill and swallow it, so pushed the crayfish that it was holding against a log to ram it down its throat.

Yep, it’s legit. Also a waste of the taste of crayfish. Reptiles eh?

Their large prey would either be carrion, or killed from the result of their venomous bite. So probably does not need a strong bite to eat its prey as it is not fighting back or trying to escape.

Finite-element analysis of biting behavior and bone stress in the facial skeletons of bats.

used Strand7, which is an Australian FEA package (which I spend a good part of my days playing with).

The animal has evolved to have that sort skull, with useful features being advantaged, whilst redundant features disadvantaged or bypassed.

So annoying that you can’t actually buy good computer programs any more, only rent them.

Have you checked? As far as I know you can still buy Strand7 with a one off payment, and continue to use it if you choose to discontinue the annual support payment.

That’s what I did with MS Office

I’m not sure what “standard of play” means.

Many companies require an annual fee, and if you don’t pay it the software stops working. Others, including Strand7, you pay an annual support fee if you choose to, but if you don’t it keeps working.

much as with other conversations, despite placement of response immediately following another contribution, it may in fact be a response to an earlier (for example from mollwollfumble) contribution

the idea that we “buy software” is for the end user typically not so correct as {we buy rights to use software}
