Friday Squid Blogging: Jurassic Fish Chokes on Squid

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2026/04/friday-squid-blogging-jurassic-fish-chokes-on-squid.html

Here’s a fossil of a 150-million year old fish that choked to death on a belemnite rostrum: the hard, internal shell of an extinct, squid-like animal.

Friday Squid Blogging: Squid in Byzantine Monk Cooking

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2026/03/friday-squid-blogging-squid-in-byzantine-monk-cooking.html

This is a very weird story about how squid stayed on the menu of Byzantine monks by falling between the cracks of dietary rules.

At Constantinople’s Monastery of Stoudios, the kitchen didn’t answer to appetite.

It answered to the “typikon”: a manual for ensuring that nothing unexpected happened at mealtimes. Meat: forbidden. Dairy: forbidden. Eggs: forbidden. Fish: feast-day only. Oil: regulated. But squid?

Squid had eight arms, no bones, and a gift for changing color. Nobody had bothered writing a regulation for that. This wasn’t a loophole born of legal creativity but an oversight rooted in taxonomic confusion. Medieval monks, confronted with a creature that was neither fish nor fowl, gave up and let it pass.

In a kitchen governed by prohibitions, the safest ingredient was the one that caused the least disturbance. Squid entered not with applause, but with a shrug.

Bonus stuffed squid recipe at the end.

Friday Squid Blogging: New Squid Species Discovered

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2026/01/friday-squid-blogging-new-squid-species-discovered.html

A new species of squid. pretends to be a plant:

Scientists have filmed a never-before-seen species of deep-sea squid burying itself upside down in the seafloor—a behavior never documented in cephalopods. They captured the bizarre scene while studying the depths of the Clarion-Clipperton Zone (CCZ), an abyssal plain in the Pacific Ocean targeted for deep-sea mining.

The team described the encounter in a study published Nov. 25 in the journal Ecology, writing that the animal appears to be an undescribed species of whiplash squid. At a depth of roughly 13,450 feet (4,100 meters), the squid had buried almost its entire body in sediment and was hanging upside down, with its siphon and two long tentacles held rigid above the seafloor.

“The fact that this is a squid and it’s covering itself in mud—it’s novel for squid and the fact that it is upside down,” lead author Alejandra Mejía-Saenz, a deep-sea ecologist at the Scottish Association for Marine Science, told Live Science. “We had never seen anything like that in any cephalopods…. It was very novel and very puzzling.”

Friday Squid Blogging: Squid Camouflage

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/12/friday-squid-blogging-squid-camouflage.html

New research:

Abstract: Coleoid cephalopods have the most elaborate camouflage system in the animal kingdom. This enables them to hide from or deceive both predators and prey. Most studies have focused on benthic species of octopus and cuttlefish, while studies on squid focused mainly on the chromatophore system for communication. Camouflage adaptations to the substrate while moving has been recently described in the semi-pelagic oval squid (Sepioteuthis lessoniana). Our current study focuses on the same squid’s complex camouflage to substrate in a stationary, motionless position. We observed disruptive, uniform, and mottled chromatic body patterns, and we identified a threshold of contrast between dark and light chromatic components that simplifies the identification of disruptive chromatic body pattern. We found that arm postural components are related to the squid position in the environment, either sitting directly on the substrate or hovering just few centimeters above the substrate. Several of these context-dependent body patterns have not yet been observed in S. lessoniana species complex or other loliginid squids. The remarkable ability of this squid to display camouflage elements similar to those of benthic octopus and cuttlefish species might have convergently evolved in relation to their native coastal habitat.

Friday Squid Blogging: Giant Squid Eating a Diamondback Squid

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/12/friday-squid-blogging-giant-squid-eating-a-diamondback-squid.html

I have no context for this video—it’s from Reddit—but one of the commenters adds some context:

Hey everyone, squid biologist here! Wanted to add some stuff you might find interesting.

With so many people carrying around cameras, we’re getting more videos of giant squid at the surface than in previous decades. We’re also starting to notice a pattern, that around this time of year (peaking in January) we see a bunch of giant squid around Japan. We don’t know why this is happening. Maybe they gather around there to mate or something? who knows! but since so many people have cameras, those one-off monster-story encounters are now caught on video, like this one (which, btw, rips. This squid looks so healthy, it’s awesome).

When we see big (giant or colossal) healthy squid like this, it’s often because a fisher caught something else (either another squid or sometimes an antarctic toothfish). The squid is attracted to whatever was caught and they hop on the hook and go along for the ride when the target species is reeled in. There are a few colossal squid sightings similar to this from the southern ocean (but fewer people are down there, so fewer cameras, fewer videos). On the original instagram video, a bunch of people are like “Put it back! Release him!” etc, but he’s just enjoying dinner (obviously as the squid swims away at the end).

Friday Squid Blogging: Vampire Squid Genome

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/12/friday-squid-blogging-vampire-squid-genome.html

The vampire squid (Vampyroteuthis infernalis) has the largest cephalopod genome ever sequenced: more than 11 billion base pairs. That’s more than twice as large as the biggest squid genomes.

It’s technically not a squid: “The vampire squid is a fascinating twig tenaciously hanging onto the cephalopod family tree. It’s neither a squid nor an octopus (nor a vampire), but rather the last, lone remnant of an ancient lineage whose other members have long since vanished.”

Friday Squid Blogging: Pilot Whales Eat a Lot of Squid

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2025/11/friday-squid-blogging-pilot-whales-eat-a-lot-of-squid.html

Short-finned pilot wales (Globicephala macrorhynchus) eat at lot of squid:

To figure out a short-finned pilot whale’s caloric intake, Gough says, the team had to combine data from a variety of sources, including movement data from short-lasting tags, daily feeding rates from satellite tags, body measurements collected via aerial drones, and sifting through the stomachs of unfortunate whales that ended up stranded on land.

Once the team pulled all this data together, they estimated that a typical whale will eat between 82 and 202 squid a day. To meet their energy needs, a whale will have to consume an average of 140 squid a day. Annually, that’s about 74,000 squid per whale. For all the whales in the area, that amounts to about 88,000 tons of squid eaten every year.
