Hey @beingcuteismything someone else wrote about moon snails before I could!

I studied predation rate and preference (do they exhibit a preference for native clam species over commercially farmed introduced clam species?) for my final project.

And then the middle school kids saw our moon snails mating in the touch tank, as I have mentioned.

I saw you reblogged a moon sail, have you ever posted about their egg cases? I visited the beach one time in Washington during a super low ride and saw a lot of them and even a whole moon snail!! We didn't touch it but it was so darn cool.

no, but I HAVE talked about their murderous tendencies!

so if you live on the cascadian coast, you may have found shells with weirdly precise holes in them that look like they were bored by a rogue etsy seller with a dremmel:

well tldr, moon snail done it.

see, moon snails are predatory! they feed entirely on other snails and bivalves like clams, which they kill by rasping a hole through their shell with an extendible mouthpart called a radula that resembles an extendible chainsaw, then injecting it with a digestive enzyme and slurping up the resulting ex-animal soup.

the entire process takes about five days! talk about a way to go.

not bad for an animal that looks like a deflated bike tire under a croissant!

(maybe don't pick them up though)

Art Studio 1 Research: Biology of Slime (IDEA 2) PART 2

Artist Archive (both ideas): Markos Kay's aBioGenesis (2022)

aBioGenesis (2022, CGI-animated short film (57 secs))

Markos Kay's works exist in between art and biology, in this case creating a visual 'reimagining' of the theory that early cellular life originated from 'primordial lipids'.

Organic forms (droplets, bubbles, vesicles/vacuoles, veins, flowers, cells, etc.) could perhaps influence how my 'slime-inspired work' may look (abstract?).

Abstract/biomorphic animation is definitely something I may use for my own work.

Artist Archive (both ideas, but primarily idea 2a): Aron Sanchez-Baranda

1st Row (left to right) - photographic prints: Fundament, Pisaster ochraceus/Anthopleura xanthogrammica (2021), Hair, Gum and Blood, Stemonitis sp. (2019), Febrile, Urticina eques (2021)

2nd Row (left to right) - short film screencaps: Take me to your heart, Phoca vitulina birth remnants (2017), Higher class tissue, Octopus rubescens (2021), Proportion dependent, Anthopluera sola (2023)

3rd Row (left to right) - short film screencaps: Cell wall, Aplysia californica (2023), World entire, Anthopluera sola (2023), Transactive memory, Anthopluera sola under UV light (2022)

4th Row (left to right) - short film screencaps: Lap, Neverita lewisii (2021), Cooperation offer, Ophiodromus pugettenis lives within patiria miniata (2022), Sparkling reflective stacks of purine crystals, Flabellinopsis iodinea (2023)

Aron Sanchez-Baranda's photographs and films exist as both documentation and art.

His close-ups of fungi and marine wildlife abstract the natural forms of the subject, focusing on the colours, the patterns, the shapes and textures interacting with each other, and the glistening water, mucus, etc. of their surfaces.

This may perhaps play into the natural vs. unnatural, familiar/comfortable vs. repulsive?

Artist Archive (both ideas, but primarily idea 2b): Anicka Yi's tempura-fried flower sculptures and artificial honeycomb lamps

1st Row (left to right): Maybe She's Born With It (2015), ALZ/AZN (2015), Lapidary Tea Slave (2015)

2st Row - tempura-fried flower sculptures: Installation shot of all three sculptures listed about

1st Row (left to right) - artificial honeycomb (epoxy resin) lamps: Escape From The Shade 1 (2016), Escape From The Shade 7 (2016), God Make It This Time Or Never At All (2017)

2nd Row (left to right) - artificial honeycomb (epoxy resin) lamps: Mausoleum Of Easy Going (2017), Slippage Between Law and Art (2022), One Bright Pearl (2022)

Anicka Yi is another artist who explores biology and art, but more within the context of sensory immersion and how it may trigger emotional responses.

In the case of her tempura-fried flower sculptures, the strong smell of oil, tempura batter and decaying plants exudes from a hybrid between crystallised and molten/dripping forms (interesting to play with both shape/texture and smell).

As for her artificial honeycomb lamps, she transforms the 'honeycomb' into a 'draping cloth' while maintaining its texture and translucency - with colours ranging from softer and more natural to more vibrant and emotive (perhaps textured sculptures and light/colour for a tangible, interactive form?).

Lewis’s Moon Snail

Neverita lewisii

Cepaea nemoralis (Grove snail) and the shell of Neverita lewisii (Lewis's moon snail)

A garden is not just a space for pretty flowers, it’s also full of ‘critters’. Exhibit A; the Grove snail. This little land snail is native to Europe and appears prominently on The Invasive Species Council of British Columbia’s list of nasty imports. However, the shell it’s climbing over is from a moon snail we picked up twenty years ago on a beautiful, deserted beach in Haida Gwaii (formerly known as the Queen Charlotte Islands).

The Grove snail has been of interest to evolutionary biologists because the bright bands of color must attract predators. How did this trait evolve? As a survivor of several hundred dancefloors in my youth (and thinking back to some of the garish outfits I wore) I have an obvious explanation - “It’s because ‘chicks’ dig it!” Any more questions?

Wanna see the ugliest animal in the world?

Behold Neverita/Polinices lewisii, the moon snail. It is, in fact, a marine snail whose mantle, unlike most other gastropods, extends out of the shell and partially envelops it.

I love this stupid thing.

May I please have invertebrate... 🤲

this one is lewis' btw

The giant Lewis' Moon Snail - Neverita lewisii (Syn. Euspira lewisii)

Lewis' Moon Snail, Neverita lewisii (Gastropoda - Naticidae), is a huge sea snail native to the Pacific Ocean coast of North America, from Canada to Baja California, Mexico). This is the largest of the moon snails, with shells up to 13 cm in diameter, however a fully expanded animal is several times larger than its shell. The snails plough forward with a foot just below the surface of the sand. When extended, the foot can measure over 30 cm in diameter.

Moon snails feed mostly on clams, mussels, or other mollusks. They are “boring predators”, meaning that they drill through the shell of their prey and ingest the tissue inside. In order to drill a prey item successfully, they must first detect and immobilize their prey, cover it in a mucus sheath and then transport it into the sediment to be drilled. Moon snails use a combination of an acidic enzyme and a “rasping tongue”, the radula, to penetrate their shelled prey. The radula, located at the end of the proboscis, scrapes the surface of the shell as the proboscis rotates 90 degrees, resulting in a fairly round and smooth borehole with an inner and outer edge. The accessory boring organ, located in the snail’s foot, secretes the acidic enzyme to soften the shell of the prey.
