For this weeks #SundayFishSketch I'm staying close to home and painted the Shorthead Pirate Perch, Aphredoderus mesotrema. David Starr Jordan first described this in 1877 as a new species of Pirate Perch due to it's intermediate cloachal position. And later determined this was only a juvenile...

The type specimen was in poor condition, lacked diagnostic data, and was subsequently lost. Last year I had to assign a species to this name, and I chose the illustrated species as it was likely the species Jordan was looking at...

Jordan thus described a new species unwittingly, and it wasn't until 2024 we had an actual description for this species.

Asian arowana, Scleropages formosus, for this week's #SundayFishSketch. Widely considered to bring good luck. These are endangered in their native range.

This week for #SundayFishSketch I drew a lesser seen species from the group of fishes that first got me interested in ichthyology. Cynodon gibbus belongs to the dogtooth characins, Cynodontidae, from South America.

The most famous Cynodont is arguably Hydrolysis armatus, or the payara as seen on River monsters. Sizes range dramatically however, with some reaching only 12-15" as adults.

It was absolutely mind bending to me to see such ecological and behavioral diversity in a group of fish that I had previously thought were on the bottom of the Amazonian food chain.

Cynodontidae are a group of highly specialized piscivorous tetras that use large fangs to impale prey and deflate their swim bladder before spitting them out to reposition so they can swallow them head first.

A Longnose Gar for #SundayFishSketch #25DaysOfFishmas. After a few years of trying to catch one my first ever was caught nighttime micro fishing. Since moving to NC they are hard not to catch!

My guess for #SundayFishSketch #25DaysofFishmas was the Fathead Minnow, also called the Rosy Red Minnow in the fish trade. It's a common bait species, and highly invasive is Europe, and less so outside of it's native range in North America.

Here's my rainbow trout for #25DaysOfFishmas #SundayFishSketch. While I lived and fished in the Great Lakes I've never seen the steelhead form before!

Hi Bluesky, I am happy and optimistic to be here! Anyone know a freshwater fisheries biologist into teaching who might want to come join me in the beautiful Ozark streams of SW Missouri? Please share/repost.

Largemouth and Smallmouth Bass…and 17 other species of black bass?! 🤯 Yup! And almost all of them are of conservation concern within their native streams of the southeastern USA. #BlackBassDiversity #Fishsci doi.org/10.1002/fsh....
