Here is a sneak peak of some of the animation using the motion capture pipeline for body and face expressions.

Sepia (cuttlefish) skin is just at complicated but a high density display...

Squid are amazing. Here is a confocal microscopy image stack showing inside squid skin highlighting nerves (red tracks) & chromatophores (and their muscles).Iridophores (white puffy clouds) and scattered iridocytes, produce dynamic iridescence that is neurally controlled.

Ok so its #Invertober2022 and #Inktober ! Does that mean two excuses to tweet about cephalopods....why not...Soon we plan to get back to working with pelagic squids (thanks @shelby_temple for the beautiful pic).

Big thanks to @USNavyResearch for their support of this research, undergrads (Tanner @ToeBiterTanner, Matthew, Jacob), Chuck (octopus supplier), UMN admin, shrimp & crab suppliers, @FedEx for making ceph research possible in the Midwest.

Ipsilateral (same side) recruitment for each of the arms, for prey capture, was almost identical for left and right eyes (when overlaid) across 10 animals tested, implicating a functional bilateral symmetry for arm recruitment decisions in the brain.

Octopus always used arms on the eye viewing the prey. Arm 2, the second from the midline, on the side the eye was viewing, was used 9/10 animals. For sequential arm recruitment for shrimp capture, Arm 2 was almost always used as part of prey capture, followed by neighbor arms.

We tested two prey types, fiddler crab and white shrimp as they have very different escape behaviors that our octopus were already experienced capturing in our tanks. This allowed us to see if different arms maybe recruited for different prey.

The cuttlefish are also really good at camouflage here blending into a filter block.

Our cuttlefish @umncbs appear to be happy to share a den! And growing fast! Thanks @FlavieBidel for helping these guys grow well.

And the octopus always have an eye on us...Do you have the shrimp?

Finally I have the trifecta of cephalopods! and in the Midwest @ UMN. We have squids (Euprymna berryi), cuttlefish (Sepia officinalis) and Octopus (bimaculoides). Nine cuttlefish hiding here after their fiddler crab dinner. @umncbs @UMNews

In addition to the lab’s own 2-photon microscope, the post includes access to electrophysiological rigs (intracellular and extracellular), high-speed video cameras, behavioral arenas, and various fieldwork sites.

Spotted in Falmouth, cape cod. Almost as exciting as the real bimaculoides!

The monarch caterpillars are out in our garden today! Few days old on the milkweed. Today is sunny and 37 deg celcius in Minnesota. Summer is definitely here.

Spring has come to Minnesota early! Happy to have made it through this winter. Stay safe everyone and celebrate your vaccination when you can get one.

Our easygoing cuttlefish have made it to a coloring book! Thanks Sam Montoya for this example!

Happy #WorldOctopusDay Octopus have a cool beak to help inject venom that disables crabs, their favorite meal. Check out the relative size of the beak in this week old Octopus bimaculoides.

Functional imaging in the medulla using the system revealed processing differences between different layers with respect to color. Now we need to look more closely at which neurons are responsible.
