But this is a Cyematid not a nemichthyid. Although they have similar jaw shapes and Velcro like teeth, they are not closely related with bobtail eels being related to gulper and pelican eels.

I think that’s a reasonable guess! Cool video!

Vinicius Espindola can speak more to this than me

Great question- if I recall, not a true tooth but projection from ethmovomer

Second record and range extension of the one‐jaw eel, Monognathus jesse, from the northeastern Pacific Ocean (Anguilliformes: Monognathidae) Herein, we report the second known specimen of the one-jaw eel, Monognathus jesse, collected in 4200 m of water, between 1748 and 2001 m depth, in the northeastern Pacific. This specimen is the secon...

Specimen SIO 23-94 is now part of the Scripps Marine Vertebrate Collection and available to science! Consider helping us continue our work on documenting the deep-sea fish diversity! See the link below to support giveto.ucsd.edu/giving/home/...

We collected tissue samples and @arciladk.bsky.social was able to generate a mitogenome for this species and compare it with related eels, such as gulper eels, bobtail eels and snipe eels.

These eels lack an upper jaw and instead have a venomous fang in the roof of their mouth that you can see on this CT scan. They presumably use this to immobilize large red crustaceans, their favorite prey.

It matches Monognathus jesse, previously known from only ONE specimen collected near the Line Islands in 1960 (catalog number SIO 60-245).

From 1,750–2,000 m deep, we collected one of the rarest deepsea fishes out there: a one-jaw eel (family Monognathidae). Only ~100 specimens of this group are known worldwide and we hold the largest collection (~46), most just a few inches long… The one we collected though, 6 inches or 154 mm!

Back in Pct 2023, @scrippsocean.bsky.social Professor Anela Choy invited me on a research cruise hundreds of miles off California to study open ocean Goodwin’s. I helped ID deep-sea fishes collected via a MOCNESS net system (opening–closing trawl with known capture depths)

Four large female Pacific Footballfish (a rare species of anglerfish) that have washed ashore in California recently and been preserved in museum collections for documentation and future research.

Over the past 5 years some rare Pacific Footballfish have washed ashore in California. How rare? 41 individuals ever recorded, rare. So @realfishdoc.bsky.social, @frable.bsky.social, Michelle Horeczko, and I wrote a short note summarizing this species. Check it out here: doi.org/10.51492/cfw... 🐟🦑

Manuscript accepted! Good way to start the week. Can’t wait to share the paper led by @planet-of-fishes.bsky.social with @frable.bsky.social, me, and Michelle Horeczko when it comes out.

My favorite photograph taken at SIO Marine Vertebrate Collection yesterday. Alepisaurus ferox @scrippsocean.bsky.social @frable.bsky.social

Our friend Francesca recently spotted this cool creature washed up on La Jolla Shores, so naturally we had to phone our other friend Ben Frable (@frable.bsky.social), manager of the Marine Vertebrate Collection here at Scripps Oceanography. 🐠 Here's what he had to say. ⬇️

A tour of Scripps Institution of Oceanography's Marine Vertebrate collection The collection contains specimens of more than two million species of fish.

The Scripps Oceanography Marine Vertebrate Collection is home to nearly 2 million fish specimens! Collection manager @frable.bsky.social gave CBS8 a special inside look at the collection, spotlighting fish that were collected as early as 1886! Dive deeper into the Collection. ⬇️

Yeah it’s unfortunate. I think they had it written before talking to me. Luckily, they put in some of my comments on this towards the end of the article

A Deep-Sea Fish of Nightmares Strays Into Shallow Waters A scary-looking creature with “devil” in its name was spotted close to the surface off Tenerife, a Spanish island.

😈 A rare sight with an ominous name— a black seadevil anglerfish was recently spotted off the coast of Tenerife. Ben Frable (@frable.bsky.social), manager of the Scripps Oceanography Marine Vertebrate Collection, shared more about this cool creature for @nytimes.com. ⬇️

Stay tuned!

@neilshubin.bsky.social lectured at @scrippsocean.bsky.social a few weeks ago, I was out of town but got the grad students to get my stuffed Tiktaalik signed! #walkingfish #paleontology

The new entrance to the Marine Vertebrate Collection! An amazing mural by Dwight Hwang of California ichthyofauna. Offshore to nearshore, shallow to deep; from the oarfish and footballfish to sardines and finescale triggerfish. Brought to life by the amazing @birchaquarium.bsky.social Exhibits team!

“Keira Knightley, wearing an unacceptable hat,…” always stuck w me from this.

No, that is the main library (Geisel) on UCSD main campus

Deep-Sea Benthic Biologist - Assistant Professor University of California, San Diego is hiring. Apply now!

Come join us! Would be great to get more fish people at SIO!!

😍😍😍 can’t wait!

Even more secret there’s a male on it ;)

A photo of a museum specimen of Coilia dussumieri. The fish has a long body that tapers to a point, with a whip-like tail. The pectoral fin is placed far forwards, while the anal fin runs along the base of its tail. The pectoral fins are long with thread-like rays that branch out, and the head is pointed.

We're finishing off our counterillumination topic with the fifth fish of #25DaysOfFishmas, the goldspotted grenadier anchovy, Coilia dussumieri. Like yesterday's fish, C. dussumieri uses symbiotic bacteria, housing them in shiny organs that run along the length of its body.
