The OctoPost: Stinky Ink, Schools, and a Beanie

I’ve been loving World of Wonders: In Praise of Fireflies, Whale Sharks, and Other Astonishments by Aimee Nezhukumatathil. It has a wonderfully whimsical description of the octopus’s distributed nervous system (newly discovered to be segmented!) which I just had to doodle.

A drawing in black ink of an octopus with one of its arm tips folded into the shape of an asterisk. Another arm is holding open a book that reads
“Each arm of an octopus forms an asterisk that we might as well apply to any statement we make now about its intelligence.”

Cephalopod News

Ink is a superpowered multitool. Cephalopods deploy it as an obscuring smokescreen, a distracting decoy, or even a theatrical backdrop! New research on cuttlefish shows that ink can also gum up a shark’s sense of smell.

[M]elanin, responsible for the dark color of a common cuttlefish’s ink, possesses a molecular structure and other properties that let it strongly stick to all the tested [shark] smell receptors. Melanin’s binding affinity for the receptors surpassed that of the compound responsible for mammal blood’s metallic odor.

At least one scientific database is suffering, not at the hands of the US government, but due to simple deterioration over time: the Tree of Life, long the most reliable online repository of cephalopod information, but increasingly difficult to update and access.

A group of scientists have begun migrating its contents to the new CephRef site, along with “molecular information, live imagery and links to video observations in their natural habitats.” They’ve set up a GoFundMe to build and maintain CephRef, and scientist-artist Meg Mindlin curated a set of cephalopod art cards to raise additional money. I contributed my drawing of the martial artist pygmy squid Kodama jujutsu to this glorious collection!

A graphic showcasing ten cards of various different cephalopods all drawn by different artists. Text reads “Multi-Artist Collab. Cephalopod Art 10-Card Set. Profits support the cephref initiative. Help support a new home for cephalopod biology resources.” A green arrow points toward my contribution: a drawing of a pygmy squid wrestling with a shrimp.

My News

I had a splendid visit to Battle Creek, Michigan, where I got to talk about octopuses at both Willard Library and Lakeview Middle School. The kids were full of knowledge, questions, and ideas. ("You should draw an octopus as Deadpool because they can both regenerate." Yes, anonymous fifth grader, I should.) Many thanks to librarians Brenna LaForge and Wendy VanderWeele for hosting me! The Willard library talk—complete with a mural backdrop even better than squid ink—can be viewed here.

Photo of me, wearing a black dress with a red octopus on it, standing and gesticulating in front of a very dynamic and colorful mural on the wall of the library.

Closer to home, I got to join a crew of local authors at the California School Library Association meeting in San Jose. It was super enriching for me (and hopefully for the audience) to talk on a nonfiction panel with so many amazing writers. I learned about the five kinds of nonfiction! I also loved meeting myriad magnificent librarians, especially the Oakley Union gang who joined my dinner table en masse—en kind, welcoming, and enthusiastic masse. Gobs of gratitude to heroic organizer and author Virginia Loh-Hagan!

In March, I’ll be part of Los Altos High School Writers’ Week. I adore visiting schools, so please reach out if you’d like to connect me with one!

Did you know there’s a squid called Brachioteuthis beanii?

Ink and marker drawing of a Brachioteuthis beanii squid wearing a beanie. The squid is golden and pink; the beanie is gray. The hat is properly situated on the squid's head, not its mantle.
I hope you are as warm and cozy as this squid.
