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).

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.”

A meter-long flying neon squid (Ommastrephes bartramii) was found dead on an Israeli beach. The species is rare in the Mediterranean.

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.

Research:

Nondestructive detection of multiple dried squid qualities by hyperspectral imaging combined with 1D-KAN-CNN

Abstract: Given that dried squid is a highly regarded marine product in Oriental countries, the global food industry requires a swift and noninvasive quality assessment of this product. The current study therefore uses visible­near-infrared (VIS-NIR) hyperspectral imaging and deep learning (DL) methodologies. We acquired and preprocessed VIS-NIR (400­1000 nm) hyperspectral reflectance images of 93 dried squid samples. Important wavelengths were selected using competitive adaptive reweighted sampling, principal component analysis, and the successive projections algorithm. Based on a Kolmogorov-Arnold network (KAN), we introduce a one-dimensional, KAN convolutional neural network (1D-KAN-CNN) for nondestructive measurements of fat, protein, and total volatile basic nitrogen….

New research (paywalled):

Editor’s summary:

Cephalopods are one of the most successful marine invertebrates in modern oceans, and they have a 500-million-year-old history. However, we know very little about their evolution because soft-bodied animals rarely fossilize. Ikegami et al. developed an approach to reveal squid fossils, focusing on their beaks, the sole hard component of their bodies. They found that squids radiated rapidly after shedding their shells, reaching high levels of diversity by 100 million years ago. This finding shows both that squid body forms led to early success and that their radiation was not due to the end-Cretaceous extinction event.
