Holy shit I finally finished it! The interconnectivity of the British Columbian marine ecosystem is one of my favourite things in the world, so here are a few treasured icons.

"Some species of sea urchins use shells as hats to feel more secure and camouflaged. And apparently, if you give them little hats, they'll wear them for protection. See? - Source: I don't remember, sorry

So this deviated hard from what I originally planned, so uh. I guess this is the beginnings of an isat Octo expansion au.

Sif, taking on the role of an amnesiac traveler trapped in the subway and its tunnels with a finicky relationship with death and time. Wandering and trying to find purpose when he happens upon an Urchin named Loop (who’s debatably even a sea creature) who seems to know more about him than even himself. Teaming up to figure out what the shell is going on, they traverse the deep sea metro. (I have very little idea about this au at this time but hey, a starts a star)

People seemed to appreciate the tutorial I posted so here is another one. Here is how you can stitch a 3D sea urchin (without the spines). This one is a bit more advanced and needs some descrioption to accompany the images.

Technique: The technique is called woven picot. If needed you should be able to find better stitch instructions on youtube.

Threads and yarns: I've preferred using a twisted thread for the woven picot. In the tutorial I'm using sashiko thread, and that worked ok but wasn't ideal. I would recommend cotton perle or mercerised cotton crochet yarn for this technique. The top example is mercer cotton. The tighter the thread is twisted the better I'd say. I do NOT recommend using six-stranded floss.

Variegated thread is fun for this project. If the randomeness of it bothers you then you can cut out lighter and darker sections of your variegated thread and then do every other wedge of woven picot darker and every other lighter, as I've done in the top example.

The yarn in the middle is some really chunky wool knitting yarn, which is a bit of a struggle to work with. You could also just ball some yarn up, pack in there and fasten it with some stitches with a thinner thread. It's not going to be visible anyway, so you can improvize.

Needle: A blunt needle is better for this technique too, but I only had sharp ones at the time I made this tutorial. Don't be like me.

Process: I'd say the pictures are pretty self explanatory, but here is a brief rundown. Draw a circle on the fabric, in the size you want your sea urchin to be. Split this circle in to five equal sections. A sea urchin typically has a patter that is made up of five broader wedges interspersed by five narrower wedges, so that's what we want to achieve. So when you have your five sections, try to sketch out five broad and five narroow sections using the lines you've already drawn as a guideline.

Make the wedges as pictured above. Each wedge needs to be of equal length and a bit longer than the radius of the circle.

Fill the middle with som padding, as described above. I've made five puffs of padding, one for each broader wedge. Which leaves little valleys for the narrow wedges to rest in, and creates a shape typical of some sea urchins. The woven wedges are then simply joined together as neatly as possible with a thin thread of similar color (I just split the sashiko thread down to half the thickness and used that).

Lastly I finished the edge of the hole in the middle with some button hole type stitches maybe? I'm shit at stitch names... Beading is optional, I just thought it looked neat.

The kelp's holdfast, its crucial attachment to the rocks, is incredibly tough. Each sea urchin has five teeth, which are self-sharpening and are replaced every few months. With them the urchins fell vast areas of kelp, creating clearings known as "urchin barrens". BBC | Planet Earth

Phylum #6: Echinodermata!

Starfish! And sea urchins, sea cucumbers and other little creatures! All of them are united by having a hard skeleton made of tiny elements called ossicles. They also have hundreds of little tube feet, powered by a entirely water pressure-based vascular system!

They're also pretty unique among bilaterians for having switched their usual bilateral symmetry for a five-way one (yes, urchins have a five-pointed star under their spikes!). Even weirder, some of them like sand dollars and sea cucumbers switched again, and got their bilateral symmetry back!

Most echinoderms are pretty familiar, but some can take on pretty unique shapes. Crinoids are filter-feeders shaped like large feathered tufts - some fixed on a stalk, while other can walk or even swim by themselves, undulating through the ocean. Until the Jurassic, reefs and rafts of crinoids floating on driftwood were extremely common, at the heart of most marine ecosystems!

Sea cucumbers are also known to exhibit quite interesting forms among echinoderms, with Pelagothuria being nearly jellyfish-like in appearance!
