new species for #molluscmonday #wormwednesday !

[New Paper] Provides the first description of cold seep fauna in the Sea of Japan, revealing just a few species living in very cold water. We also found a new snail species -- named Provanna cocytus after the icy hell in Dante's "Divine Comedy"!

We would occasionally have Moon Snail egg casings at the touch tank in Pacific Science Center, because people thought they were rubber trash, and throw them in the garbage.

My favorite thing to do was wait until the kids had been handling it, then explain how it’s made of sand, eggs and butt snot.

We’d like to tell you a joke about this squid, but it might fly right over your head.🦑 The #TaludContinental_IV team suspects this gorgeous creature may be Ommastrephes bartramii — a red flying squid. They can use their siphon as a jet propulsion system to launch out of the water & evade predators.

In honor of World Squid Day, here's a Moroteuthopsis longimana fr #SouthSandwichIslands. International cephalopod awareness days happen each year in Oct — we celebrate octopuses on the 8th, in honor of their 8 arms, and squid on the 10th, to acknowledge their ten appendages (8 arms and 2 tentacles).

A #Taleof2Canyons & an octopus! 186m, Patagonian red octopus, or Enteroctopus megalocyathus, hovering over a patch of sediment, lighter in color than the surrounding area, the cephalopod opened up like an umbrella to feed, likely on a crustacean. Read more: www.instagram.com/reel/DQnH14c...

All ink, no stink!

Squid ink is a natural, dark-viscous fluid primarily composed of melanin pigment, mucus & water — like a deep-sea smoke screen for a hasty getaway. These ink-blob shapes are called pseudomorphs. Filmed during #OBVI #LivingBioreactors expedition w/@schmidtsciences.bsky.social.

These deep sea videos are so relaxing. 😍

I feel like this is what every squid I see is telling me this exact thing.
Gonatus carrying an egg mass from #SchmidtOcean dive 739 from the #ChileMargin expedition.
They're still on the way to Bellingshausen Sea, where the next expedition is, but they should be there soon. #MarineLife

Large red squid in a missile shape, holding onto a big sheet carrying thousands of tiny eggs.

A side view of the same dark red squid holding onto her egg sheet with her tentacles. It looks like she's eating them the way they're pulled all the way up to her mouth. While brooding her eggs she will not eat, so she doesn't really need her mouth much anymore I suppose?

Top down view of the tentacles holding the eggs mass. The tentacles on this squid appear puffy and swollen compared to others of this species that I've seen. My best guess is this is a part of sensesce that the females undergo after they're done brooding.

Pilots found 2 Gonatus onyx carrying eggs sheets this expedition. Both times the eggs were hatching & they managed to collect some babies & eggs. Look at how puffy her tentacles are! After hatching, she will pass away.
