Cressida cressida, the clearwing swallowtail or 'big greasy' butterfly. Large and conspicuously coloured - it is toxic to potential predators. Toxins are absorbed from the food that it eats as a caterpillar. Seen in Cape York. FNQ.

Amazing these otherworldly creatures inhabit the little ol' English coast. Unlike other #Devon #ctenophores we saw the Northern Comb Jelly (Beroe cucumis) lacks tentacles, instead engulfing other ctenophores with huge mouth. These ancient marine #invertebrates are largest animals to swim with cilia.

Big purple starfish. (Always good to see another healthy one!) New blog post: https://wanderinweeta.blogspot.com/2026/08/chance-find.html #VancouverIsland #Starfish #Invertebrates #MarineInvertebrates #IntertidalInvertebrates #InverteFest #NaturePhotography

🦗🔬 University of #Sydney researchers found that house #crickets perform "flexible self-protection" by nursing specific injuries, suggesting they experience pain-like states rather than simple reflexes.

The directed behavior indicates a level of conscious experience previously underestimated in #invertebrates. The findings could challenge our approach toward #insects, supporting a growing scientific consensus on their complex cognitive capabilities.

Why is #JavaScript so popular? I hate everything about it.

I'm speaking at the #Canberra Field #Naturalists meeting at #ANU next month on #Malaise trapping and the #insects and other #invertebrates that surround us without our noticing them.

I expect most of my slides to be arrays of four or six #microscope images with a header (probably a family name in most cases) and captions for each image.

I don't want to lay out all these images in #LibreOffice (or any similar presentation tool) because I'm a perfectionist and getting it all tidy will take forever.

So, I decided to try out #Slidev, #Marp and other #Markdown-based presentation tools. The Markdown part is very appealing, but they all lean hard into JavaScript. That would be fine so long as I don't have to think about that side of things.

Slidev's AppleBasic theme seemed to be the best starting point, so I started hacking it to add som extra gridded image views. Plain image grids were not too challenging, but I really want captions for each image, so I started trying to understand how the templates use the forest of underlying JS libraries and CSS artefacts to produce the displayed slides.

Frankly, the whole thing is so opaque and would take me much longer to understand than preparing multiple presentations by hand would.

Then I realised I can use #montage on the command line to produce the kind of layouts I want, and I can script #exiftool to extract and prepare the captions which will save time.

So, my new plan is to write a #Python script that processes a #YAML file listing all the slides, titles and image paths. It can generate PNG images that are close to the target 1920*1080 size (give or take a little). I'll then use LibreOffice for a couple of more text-oriented or irregular slides, export those and combine all the images into a PDF.

I'm sure this will be way faster than battling Node.js. Not sure why I felt I had to write it up.

Since I’m sharing 2025 work for #artAdventCalendar, another thing I did this year was make a large collection of repeat patterns, like this Velvet worm repeat pattern! Putting more invertebrate linocuts into surface design!

These adorable, caterpillar-like blue velvet worm from New Zealand (Aotearoa). Velvet worms (phylum: Onychophora) are named for their velvet-like texture and somewhat wormlike appearance. 🧵

Watch out! This kelp crab is waiting for a chance to grab you! (On a piling under the wharf.) New blog post: https://wanderinweeta.blogspot.com/2025/12/shapes-in-murk.html #VancouverIsland #IntertidalInvertebrates #Invertebrates #Crabs #MarineInvertebrates #NaturePhotography

Everything comes to an end eventually. I've run out of good hermit photos, so I'm pausing the Daily Hermit posts for now. (Just in time for Arachtober.) Here's a GrainyHand, deciding whether it's safe to come out of the shell. He's halfway there; GrainyHands, feeling threatened, retreat deep inside, out of sight. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Say ah! A "tonsil" level view of a Grainy Hand hermit. (Who has no tonsils, but you get the idea.) 3 sets of maxillipeds, clearly visible; behind these are the small chewing and sorting appendages, the maxillae and maxillules, and at the back the strong, crushing jaws, or mandibles. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Textures; knobs and sawteeth and hairs... A Grainy Hand hermit in the sunlight. An old friend; I named him "Big Blue". #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Deceptive; it looks like an eye like ours; it's not. Hermits have compound eyes, with thousands of ommatidia, each with its own lens. Wild guess: does the black spot in the centre work as camouflage, an imitation of the lens of a vertebrate's eye? #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Hi, there! Hermits in a tank like to sit right up against the glass, watching the big world outside. Sometimes I wonder what they think of us and our frantic dashing about. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Another freshly molted hermit, waiting while her skin stretches and hardens, safely hidden high in the sea lettuce. Here in the tank there are few predators; no fish, no gulls, no octopuses. But there's always a crab or two down on the sand. Vicious little beasts, says Hermie, always ready for a snack of soft hermit abdomen! #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

The everlasting search for new togs. It's not only after a molt that a hermit decides to switch shells. You never know; this one might be more roomy, lighter, more comfortable; better check it out! #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Midnight activity; a Holm's hermit on a feeding barnacle. With a pregnant copepod and something unidentfiable; white tentacles with fuzzy tops. Many marine critters are more active at night. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Tending to the brood. Video of a Hairy hermit crab with her eggs. #HermitCrabs #DailyHermit #Invertebrates #IntertidalInvertebrates #Nature https://youtu.be/4xfEJB6vgow?si=1ufqJX_zv3CHrdAH

Big responibility. Hairy hermit, in berry, with her hundred or so eggs. She'll tend to them for weeks, moving them in and out of the shell, washing and grooming them, until they hatch and float away. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

"Furry". Like Grandad, this hermit wears a coat of epibionts, but he's younger and more recently colonized; hydroids cover both the hermit and his shell. He clutches his mate; she's fuzz-free. As are his eyes. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Barnacle, hermit, barnacles. This hermit's a Hairy, serving both as barnacle transport and barnacle clean-up crew. Essential services.#VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest

In this together. Accidental triple exposure. Focusing through folded pages of a book, the camera caught the switch between screen saver photos. Hermit, tree, sky, marine life encyclopedia, tech; we sink or swim together. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest #AccidentalPhotography

Holms' hermit, on the job. When a barnacle dies, hermits quickly clean it out, removing the interior plates, scrubbing the walls, leaving the place ready for occupancy by other critters: anemones, worms, even fishes. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest

Living in a cave? Or is that a hungry fish? I keep coming back to this pic and wondering. What was she thinking? That shell is far too big for her! Or maybe not; she flips it over and walks away with it. She's stronger than she looks. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest

Black-eyed hermit, making a mess. He's in a tidy tank in a local aquarium; so neat and clean he is, but look at the snowstorm under his shell; he's stirring up the sand in search of edibles. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit #Invertefest

Block party. A half-dozen hermits spending the afternoon together; the ones on top get a good view, but everyone benefits: comfort, companionship, shared information, safety. Maybe more; they would know. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

"How's it going, buddy?" Hermits are social critters. They spend hours just hanging out with their friends, preferably on some high spot where they can watch the world go by. Two Grainy-Hands meet on a clamshell lookout. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

Homebody. This tiny hermit lives in a tubeworm's empty tube rather than in a snail shell. She never leaves the tube; her mate visits her wearing a piece of broken tube. An uncoiled abdomen fits in tidily. #VancouverIsland #HermitCrabs #IntertidalInvertebrates #Invertebrates #MarineLife #DailyHermit

& babies develop inside their mother until large enough to be born, in batches of 4–6, as colourless miniatures of the parents! Peripatoides novaezealandiae is a species complex of velvet worms in the genus Peripatoides, found throughout NZ. My print was made based on photos of P. aurorbis, but all the P. novaezealandiae have no morphological characters that distinguish them.

At 09:09 this morning I decided it was a good time to take advantage of what the #wind had done overnight. A lot of #duckweed had accumulated in one of the bays in the #lake
visible from out lounge window.

With the aid of a angler's net attached to a long pole and a rake I managed to make a good stab of removing the weed along with some sludge and twigs found on the bed of the lake. It's now in a number of piles on the bank. I'll give it a day or two to allow #invertebrates to crawl back into the water and then move the piles to the #compost bins.

Making some new antipodean invertebrates for July, the subterranean month for #InsertAnInvert2024

You may not know the velvet worms if you live outside the tropics and in the northern hemisphere. There are 2 families of them: one in the tropics and the other, like my Lino block depicts, from the southern hemisphere (and countries once part of Gondwana). 🧵1/n
