Armadillidiidae

Just has to be Turnip's codename for the planned beach invasion of Lesser Tunb.

Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs[1] or rolly pollies.

(All that family shows convergent evolution with the myriapods like the millipedes, in morphology and pilling)

Ah yes, not all woodlice can roll up. I’ve never come across those common names though. I’ve heard a Scot call them slaters.

They are slaters here in Australia. I haven't encountered any that roll up but haven't looked hard.

No response from Ulrich so far. Given how easy to find information about evolution of tetrapods I am not convinced the OP was sincere...

it's just I've noticed this years and years agon, been searching for the reason WHY, off and on, ever since. Haven't even heard this mentioned and that's interesting in itself.

Well he does claim to be on the spectrum, so might be wired up a bit differently from you and me I suppose. But he has a range of answers now so we'll see if he was genuine, or just a drive-by creationist 😀.

They're chucky pigs here in the shires.

In Led Zeppelin's famous song, Escalator to the Celestial Realms, there is a mention of both the pill bug and the chucky pig.

"If there's a pill bug in your woodpile,

don't be anxious now,

It's just a way to break down lignin.

Dear lady there are two roads to decompose organic matter,

Your compost chucky pigs will soon be fatter...."

Not their best song, "Dazed and Confused" is my favourite... 🙃

Houses of the Holy (my ringtone, and confusingly, not on the album Houses of the Holy)

Maybe Kashmir, or When the Levee Breaks. But no, there are too many I love to pick favorites. Jimmy's acoustic is sublime on Going to California.

Never was clear on why Houses of the Holy was on Physical Graffiti. I've heard the rationale, so I have to respect the artist's choice.

Though perhaps that placement is a taxonomic error which we can relate to the thread topic. John Bonham kept so many rhythmic things happening at once that one could ask if he was more than a tetrapod*. I wouldn't rule out an extra limb somewhere in there.

* I should note that the song Four Sticks does relate to this matter of Bonham's morphology. Possibly. And Four Sticks does indeed fit the taxonomy of LZ IV, as one will note the cover art of a thatcher carrying at least four sticks on his back. The key allusion is to a multitude of sticks and the ability to use them expertly. A fact often overlooked by scholars of Zeppelin, and dirigibles generally.
