Redhorses are often studied as a group because the different species are *really* tough to tell apart, even for biologists. ID-ing them usually involves *lots* of counting of lateral scales + fin rays - the glamorous life of a fisheries biologist #25DaysofFishmas 📷: @moxostoma

Thanks again to @Lampichthys and the whole #SundayFishSketch crew for another great year of guessing and sketching #25DaysofFishmas fish! All of this year's mystery species were (unintentionally) very colorful - the bluegill, white sucker, and yellow perch!

Despite their name, it’s really the breeding males who have that intense bright green coloration - females, juveniles, and non-breeding males are more olive-yellowish in color + have 4-10 "v" or "w"-shaped marks along their sides #25DaysofFishmas

Even if you don't live in the #GreatLakes, you may have a sturgeon in your backyard! (figuratively speaking unless your backyard is underwater) - many other species of sturgeon found in the US are anadromous, meaning they spend time in both fresh + saltwater #25DaysofFishmas

With fins like those, it's probably not surprising that the threadfin rainbowfish (Iriatherina werneri) is a popular aquarium fish! In the wild, they're found in the slow-moving streams and swamps of tropical northern Australia and New Guinea #SundayFishSketch

A species that can create its own light in the pitch-black darkness and has males that are basically just parasitic sperm sacs that fuse to the females - nothing says #otherworldly quite like the deepsea anglerfish #SundayFishSketch #SciArtSeptember

Just when you thought gars couldn't get any cooler: although alligator gars eat mostly fish, they've also known to eat ducks and other waterbirds. Point goes to #TeamFish #BirdsVsFish #SundayFishSketch

As part of a lab that does a lot of salmon research, I feel like I am always thinking about this comic from Sunday Morning Breakfast Cereal https://t.co/cEVh73zinl

The adorably odd grunt sculpin (Rhamphocottus richardsonii) is named for Scottish naval surgeon and naturalist John Richardson who documented the natural history of the Canadian Arctic during voyages to find the Northwest Passage #SundayFishSketch
