i finally get to say this: I've got a new paper out with @hadalbloke.bsky.social, Joao Corona (Magnapinna Archive), Yakup Niyazi, and Denise J Swanborn: link.springer.com/article/10.1...

So hey folks, apologies here - I jumped the gun on this one. After a lot of discussion amongst various cephalopod scientists and a particularly deep dive by @cefafalopodo.bsky.social, it turns out this is not egg brooding. In fact, it’s not even a female squid!

Stauroteuthis & scaly fish @schmidtocean.bsky.social dive 979 #samplinggap #MarineLife

Sthenoteuthis @schmidtocean.bsky.social dive 980 #samplinggap #MarineLife

Bolitaenid @schmidtocean.bsky.social dive 980 #samplinggap #MarineLife

to be fair i got a bit excited and my proclamation that this observation demonstrates egg brooding was premature; it’s hard to be certain given the isolated incident and resolution of the footage. consensus seems to be at least tentatively in favor of them being eggs.

OMG Dolichopteryx! That's 2 species of barreleye this year! @jethroreading32.bsky.social @schmidtocean.bsky.social dive 976 #samplinggap #MarineLife

wake up babe new dolichopteryx observation dropped

@leapinlemurs83.bsky.social was going back through the last @schmidtocean.bsky.social expedition & found another Magnapinna that I missed. Great catch! Dive 934 part 3 #doldrums #MarineLife

🦑 Meet Planctoteuthis sp.! 🦑 According to #SamplingGap Co-chief sci Dr. Perez: “Images have finally enabled the description of this tail, but no one knows what it is used for. It looks like a siphonophore from a distance, and one hypothesis is that it could be used for siphonophore mimicry.”

Galiteuthis or Taonius. Too far for the squid squad to confirm one way or the other. @schmidtocean.bsky.social dive 970 #samplinggap #MarineLife

Cute little Chaunacops swimming @schmidtocean.bsky.social dive 970 #samplinggap #MarineLife

gorgeous encounter with a neoteuthis just now on @schmidtocean.bsky.social's dive: www.youtube.com/live/L9dQqpf...

Face finger time! Enypniastes @schmidtocean.bsky.social dive 962 #samplinggap #MarineLife

Maybe Galiteuthis (will report back is squid squad says something else) @schmidtocean.bsky.social dive 962 #samplinggap #MarineLife

well that’s a hell of a way to kick off squidtember this is a cool observation, we don’t have a ton of east pacific magnapinna sightings

I've been seeing a lot of "well I guess this is the way things are now" "ah another line of evidence that we are a fallen empire", attitude that I am begging people to shake off. There are people working their butts off to make things better. Please don't give up. Join us.

graneledone will scavenge mermaidfalls just as readily as whalefalls. the real interesting question is whether or not there are osedax worms specialized to mermaid corpses, as they are often specific to the animal they scavenge (no this is not real, i’m just riffing on one of eduardo’s works)

A midweek montage from the July 2026 #DeepWonders expedition to Trinidad & Tobago w/ @divaamon.bsky.social. The team located over 25 active cold seeps, discovered 20 suspected new species, and mapped approximately 13% of the country’s marine territory.

I think that's Mastigoteuthis? Poor squid has been through some things with those ripped off arms and tentacles @schmidtocean.bsky.social dive 959 #deepwonders

oldest sea is also fantastic: oldestsea1.bandcamp.com

i’m gonna have to side with danna, while i am of course a Squid Guy, and if you’ve never seen imagery of them “flying” you absolutely need to look it up immediately, ommastrephes is by far not the coolest option here.
