Bat Star (Patiria miniata) at Moss Cove beach in Laguna Beach. We just completed a few days of low-tide (during daylight), but next month starting around Nov. 14, it will also be a good time for tide-pooling in SoCal. Double check your local tide charts to be sure! Anything under 2 ft is pretty good for observing tide pools

#00192 BAT STAR

Patiria miniata

PHYLUM ECHINODERMATA, CLASS ASTEROIDEA

An intertidal starfish found along the Pacific coast from Alaska to Mexico. It eats both living plants and animals as well as dead detritus - it secretes digestive juices to liquefy food sources before ingesting them.

Did you name your characters after their respective animals scientific name? That's such a interesting little detail! Their names sound fresh AND there's meaning! Catch me trying to figure out the first names of all characters now 😭😭 Not sure what aquatic animal has "Johnsoni" in their name though /j

I did, I’m glad you noticed this!! I just chose a part of their scientific name that looked like it would suit them. I’m really happy with how it turned out!! Something fresh but with meaning is what I was hoping for 💕

(I’ll clarify real fast that it’s not necessary in the game’s world to be named that way! Your mc can have any name. This is just something fun I like to do instead of coming up with names.)

I’ll put it under a cut, but here’s a list for everyone:

Thaumo = thaumoctopus mimicus (mimic octopus)

Nalis = sepia officinalis (common cuttlefish)

Tremo = tremoctopus (blanket octopus)

Dr. Willani = chromodoris willani (no common name)

Johnsoni = parastichopus johnsoni (Johnson’s sea cucumber)

Orca = orcinus orca (killer whale)

I haven’t decided on names for 2 people yet. I have their scientific names, I’m just still deciding which part of it suits them most!

The childhood friend = acanthaster planci (crown of thorns starfish)

The BERE agent = patiria miniata (sea bat or bat star)

Uncharismatic Fact of the Day

Why do starfish always win? Because they're a-head! A new study of starfish genes has revealed that what we thought were arms are actually just extensions of the starfish's head, each containing DNA corresponding to various areas of the brain. This suggests that, at some point in their evolution sea stars had a torso, but lost it and became only disembodied heads. You can read more about this fascinating discovery here!

Bat Star (Patiria miniata)

Family: Cushion Star Family (Asterinidae)

IUCN Conservation Status: Unassessed

A small species of starfish found in a variety of habitats across the Pacific coast of North America, the Bat Star is named for the thin membrane that runs between its "arms", which has been compared to the wings of bats. Highly variable in appearance, members of this species are usually red with five arms but may also be yellow, brown, pink, blue or black and have anywhere from 4 to 9 arms, especially after enduring an injury or an awkward regeneration of a lost limb. As with all starfishes a Bat Star's arms are lined with chemical-sensitive cells and small light-detecting organs comparable to crude eyes, and through the use of these organs (as well as the numerous tiny tube-like feet lining their undersides) they crawl slowly along the seafloor in search of algae, carrion and immobile or slow-moving animals; lacking teeth or jaws, they feed by enveloping prey with their arms and then extending their stomachs out of a small mouth in their centre, externally digesting their food and absorbing the nutrients released as a result. Each individual Bat Star is either male or female, and when the waters around them are sufficiently warm females freely release huge number of tiny eggs into the water to be externally fertilized by gametes released by males.

What is this, you ask? Why, of course, it's the nervous system of a juvenile sea star (Patiria miniata) about 1 cm wide. Labeled with an antibody against acetylated tubulin after optical clearing, and captured using a color-coded Z-projection.

No, but seriously folks, check out the link above for more amazing miniature beauty.

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?).

Nel corso della loro evoluzione le stelle marine hanno perso il corpo per diventare solo testa

L’insolita simmetria a cinque assi delle stelle di mare (Patiria miniata) ha a lungo confuso la nostra comprensione dell’evoluzione animale. Per secoli i naturalisti si sono interrogati su cosa potesse costituire la testa di una stella di mare, comunemente chiamata “stella marina”. Quando si guarda un verme o un pesce, è chiaro quale sia l’estremità della testa e quale quella della coda. Ma con…

Basic toolkit for organ development is illuminated by sea star

Despite its fundamental importance, the general mechanisms of hollow tube formation during embryogenesis are not well understood, due to the great diversity of strategies that animals use to form tubular structures. Enter the sea star, an ancient marine creature whose process of tubulogenesis is relatively easy to study, and which is becoming an important organism for understanding the genetics and mechanics of tube formation. In the May 9 issue of Nature Communications, Margherita Perillo of the Marine Biological Laboratory (MBL) and collaborators reveal in detail the initiation and early stages of tube formation in the sea star Patiria miniata. “Most of our organs are tubular, because they need to transport fluids or gases or food or blood. And more complex organs like the heart start as a tube and then develop different structures. So, tubulogenesis is a very basic step to form all our organs,” Perillo said. Perillo chose the sea star as a research organism “because I wanted to understand the basic mechanism of tube formation that is conserved across all vertebrates. So I needed an animal that was at the base along the tree of life, [evolving] before the chordates,” she said. Using CRISPR and other techniques to analyze gene function, as well as long time-lapse movies of the developing sea star larvae, Perillo and colleagues ascertained how this organism generates tubes that branch out from its gut. Her study defines a basic toolkit from which the chordate tubular organs may have developed. (Chordates include the vertebrates — fish, amphibians, reptiles, birds and mammals — and a few invertebrate subphyla). One open question in biology was exactly how organisms develop from one cell into the complex 3D tubular structures of various organs, Perillo said. In some organisms such as flies, “there is a big round of cell proliferation before all the cells start to make very complex migration patterns to elongate, change their shapes, and become a tube,” she said. In other animals, including mammals, cell proliferation and migration occur together. In the case of the sea star, “I found that, in order for tube formation, cells can proliferate and migrate at the same time,” as they do in vertebrate development. “So, this means that this mechanism of making organs was already established at the base” or root of the evolution of chordates, she said. In addition to providing insights into the fundamental process that leads to organ formation, sea stars can serve as a model for much biomedical research, Perillo suggests. For example, she found that a gene called Six1/2 serves as a key regulator of the branching process in tube formation. In mice, knocking out Six1/2 causes kidneys to form abnormally. But researchers have found that mice lacking this gene also resist tumor formation, even when injected with tumor cells. The gene, which is overexpressed in cancer cells, could lead to new ways of studying disease progression, including cancer. “I can now use this gene to understand not only how our organs develop, but what happens to organs when we have a disease, especially cancer,” she says. “My hope is that, in five to 10 years maximum, we will be able to use this gene to test how organs develop cancer and how cancer becomes metastatic.” Sea star embryos have many practical experimental advantages, Perillo said. They are mostly transparent, so internal growth processes can be directly observed over long developmental periods without harming the organism. They are also easy to collect and breed in large numbers year-round, “so I always have a lot of material to work with.”
