An old sketch for the "rare fish" theme - lindog (Barbodes lindog) is a critically endangered (possibly extinct) cyprind fish only found in Lake Lanao of the Philippines - it used to be a commercially important food fish before declines in the mid-20th century #SundayFishSketch

Back to #SundayFishSketch with a literal take on the theme "Fish Battle Royale" - the battle between native lake trout + invasive sea lamprey in the #GreatLakes is one time when it's accurate to refer to your opponent as a "bloodsucker" (lampreys are cool in their native range!)

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
