I CAN'T BELIEVE I SAID THE WRONG PLAY 💀 Thank you so much for the gracious correction. My only excuse is that I saw Midsummer and Shrew recently only two days apart so they must have got jumbled in my fingers. I'm so glad you liked the joke and casting, hehe!

It's rather obscure: the end of the Kodama jujutsu alt text is "Both look very fierce (though they be but little)," an allusion to "Though she be but little, she is fierce" from The Taming of the Shrew. I'm glad you asked and I'm so happy you enjoy the gumball machine! 😄🤏🦑

Cool squid in an ancient Roman sea bed mosaic - looks like it has sunglasses on its head LOL! (not covering the eyes, which are visible - like if you had your sunglasses resting on top of your head)

10/10 is Squid and Cuttlefish day or #squittleday, so have some banger squid memes
The Car Salesman Slaps Roof of Car meme: A drawn image of a salesman in a suit explaining to another man who is listening intently. The salesman is gesturing to the egg mass of diamondback squid (Thysanoteuthis rhombus) floating in the sea. The egg mass is magenta and is a coiled thread of squid eggs, forming a tube that looks not unlike a slinky. Test on top reads: "Squid Egg Salesman: *slaps egg mass* this bad boy can fit so many eggs in it"A picture of Snoop Dogg (Calvin Cordozar Broadus Jr.) on the left, and a picture of Bathyteuthis squid (Bathyteuthis sp.) on the right. The squid is reddish orange and has large beady eyes with the pupils dilated. The squid is inking, and the cloud of ink looks like whisps of smoke. Text below both images reads "SNOOP DOGG SAYS ONLY ONE PERSON HAS OUT SMOKED HIM"A "The cooler Daniel" meme.

There is a year book with two pictures in the centre. The left one is labelled "Daniel" and it is a European common cuttlefish (Sepia officinalis) swimming on top of seaplants with its arms all pointed down. It is mostly brown and light brown with white on its bottom. The right picture is labelled "The cooler Daniel" and it is a European common cuttlefish in white box wearing red and blue 3D glasses. Its arms are reaching out in front of it with a spread pattern. The cuttlefish is mostly light brown with white at the bottom.Wizard pondering their orb meme. A wizard with a big bushy beard in grey robers is staring at  an orb on an ornatet stone table, except the orb has been replaced with the "squorb" (squid orb), a dead Rough Cranch Squid (Cranchia scabra) found at a beach that has its mantle in a spherical shape. The squorb has been tinted blue to match the original orb's glow. A figure is peering in the distance from a stone doorway.

Happy belated #Squittleday, October 10th, on which we celebrate the ten-armed squid and cuttlefish! I was in the woods yesterday, but here a few favorites from the archives 🦑🥂 (anyone spot the alt text Shakespeare reference?)

Though lesser-known than World Octopus Day, the International Cephalopod Days continue today, October 9th, with #NautilusNight! Here are some nautiluses I've drawn! 🥳
Detailed ink drawing of a large chambered nautilus. Two of its tentacles hang lower than the others, and a small chambered nautilus with a very large cute eye is using those two as a swing.Simple ink drawing of a colorful carousel with three orange nautiluses in place of the horses.Simple ink drawing of a brown and orange nautilus holding a purple spotted balloon. The line between two of the nautilus's tentacles curves up to look like a smile.

Happy World Octopus Day! To celebrate, here’s the first piece in my series of Octopolis tarot cards: The Fool! #octopolis #worldoctopusday #octopus #tarot
A digital illustration within a tarot card frame titled ‘The Fool’. The images is of a mimic octopus bursting through the surface of the ocean into a sunlit day. The octopus is covered in many colored stripes. It holds one arm up through which light refracts. In another arm it holds a bundle of kelp. Beneath the water is a yellow cuttlefish looking very happy.

Digital drawing of an octopus against a black background. Its eight arms are winding and twisting about wildly. Its eyes are blue, its main body pink, and its arms transition from blue at the ends, through white to pink near the body to echo the colors of the trans pride flag.

The #inktober2026 prompt "smack" naturally brought to mind a jellyfish collective, and adding a shelled cephalopod to that situation reminded me how modern argonaut octopuses ride jellies. Why couldn't Eoceras have done the same?
Simple ink drawing of a group of four jellyfish. Riding atop the bell of the center jelly is an Eoceras, a tiny ancient shelled cephalopod ancestor.

Danna Staaf @dannastaaf.bsky.social · 06/10/2026
Fun fact: I did not draw an Eoceras for the #inktober2026 prompt "cactus" but I DID spend way more than my allotted drawing time studying the Shuijingtuo Formation where the fossils were found to determine that cactus do not grow there (tho they have been imported to other parts of China) 🌵🤓

So Jeanne's birthday was 4 Vendémiaire de l'An 3, the fourth day of the first month (Vendémiaire refers to the grape harvest) of the third year. 🥳 But uh... how do we translate that to the good ol' Gregorian calendar?
French Revolutionary Calendar VENDÉMIAIRE 22 Septembre: à cette époque arrive l'EQUINOXE D'AUTOMNE & commence l'Année de l'Ere Nouvelle Après avoir mûri les deux fruits de l'automne Au signe de Thémis pâlit l'Astre du Jour VERTUMNE plus épris des charmes de POMONE Cent fois change de forme & suit son seul amour.

Jeanne was born during the French Revolution, shortly after the debut of the French Republican Calendar--part of the Republic's enormous project to secularize and decimalize everything. The first year of the republic became Year 1, and the months were renamed based on nature...

Happy birthday, Jeanne Villepreux-Power! This octopus scientist and aquarium inventor was born #OTD September 25th, 1794! However, many lovely tributes were posted yesterday, because her birthday has often been erroneously published as September 24th. Why? Let's geek out about calendars...
A grayscale digital drawing of Jeanne Villepreux-Power, slightly more than a bust--head, shoulders, crossed arms. She is smiling contentedly and perhaps a little smugly. In a stylized circle around her are all the animals she studied: snail, marten, butterfly, turtle, sea star, and of course the octopuses--common octopus and argonaut, both male and female. It was drawn by me (Danna Staaf).

French marine biologist Jeanne Villepreux-Power invented the first glass aquarium for scientific study in 1832. Her sealed tanks (with aeration & water stability) enabled live observation of sea creatures, which was revolutionary in marine research. She was born #OTD in 1794. #WomenInSTEM
Sepia-toned 1861 photograph by André-Adolphe-Eugène Disdéri of Jeanne Villepreux-Power (1794–1871), pioneering French marine biologist and inventor of the glass aquarium. She stands in three-quarter profile facing left, leaning elegantly on a tall decorative pedestal vase adorned with flowers. She wears a formal Victorian gown with a fitted bodice of intricate black lace over dark fabric, long lace sleeves, and a voluminous hoop-skirted skirt. Her dark hair is styled in a low chignon, and she gazes thoughtfully to the side in a studio setting with a neutral backdrop.

The pioneering aquarist Jeanne Villepreux-Power was born OTD in 1794. She was the first to record that some species of octopuses could use tools to pry open their prey's shells. She observed them waiting for the clam to open its shell and then jamming In a rock. 🌱🐋🧪 #HistSTM #WomeninSTEM
