Fossil fish head from the Pleistocene of Galveston, TX

‼️NEW ANGLERFISH PAPER! 🐟🎣

So excited to share the final part of my Master’s research! We explore the bizarre tacklebox of anglerfish lures and show how these fishes evolved different ways to attract prey and maybe even mates in the deep sea. 🧪🦑🌊🦇🦀

A long, whitish-gray and eyeless catfish on a dark background.

Using ultraconserved elements (UCEs) we were able to include data from several formalin-fixed specimens, including the rare troglobitic Uegitglanis from Somalia.

Pleased to share a new phylogeny for the airbreathing or walking catfishes from the family Clariidae - part of my postdoctoral work at the AMNH in collaboration with Tobit Liyandja and Melanie Stiassny: www.sciencedirect.com/science/arti...

Out now in Contributions from me and @gilespalaeo.bsky.social, a deep dive into an early member of the sturgeon and paddlefish lineage. Bear with me, but there’s a long backstory highlighting uncertainty about the anatomy of living species and how well-studied fossils can still yield new insights.

Our paper describing a new species of Pascua goby from the Coral Sea has been selected as en Editors Choice Article in Fishes. Apart from being fabulous, these fish are cool because they show that the genus has two groups of species separated by >5000km of the Pacific! www.mdpi.com/3483974 #fishes

Four incomplete fossil fish specimens on a black background. The specimens preserve scales, vertebrae, spines, and so on, and are dark gray on lighter gray to mustard-colored slabs.

Dragon in the deep. 🐉⁠
⁠
Dragonfish (family Stomiidae) are cunning predators. Although they are strong swimmers, they prefer to lie in wait and ambush unsuspecting fishes and crustaceans. This black dragonfish (Idiacanthus sp.) was spotted at 527 meters (1,729 feet) in Monterey Bay.

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!

Black and white illustration of a skeleton of a herring with already some inclinations of the internal organs. The views are dorsal, lateral and ventral.

Not finished yet and this isn’t a pen and ink illustration, but a black and white rendition of a 3d model, but I love to share this herring. Except for some bones in the pectoral fins the skeleton is all but complete

#FishADay Mitsukurina owstoni Goblin Shark. Benthopelagic, mostly near continental slopes and seamounts. Known from < 250 captured individuals, so a recent well-documented recreational rod-and-reel capture (and release!) off the Canaries is very exciting.

A bustling seafloor scene from the #taleof2canyons expedition: “We studied how these canyons can facilitate such incredible biodiversity,” said Chief Scientist Dr. Silvia Ines Romero. “What are the mechanisms — the currents and the chemistry — that support all of this life?”

A view of a river at sunset. By combining many exposures I have multiple images for single birds flying through the scene, making the appearance of trails. One bird flies in an arc across the scene close to the camera and the sunlight can be seen shining through its tail feathers.

While scanning some fishes yesterday I came across this Bonytail Chub collected near Blythe, CA in 1933. You can't find this species in Blythe anymore, nor in the rest of California as it is critically endangered. Museum collections like @nhm.org showcasing yet again our changing planet 🐟🐠
