@DrFishSG @SolomonRDavid @ericrsails @ReelAngle @donaldorth @WildlifeBioGal @UWiscSeaGrant Steelhead + rainbow trout are actually the same species, but with different lifestyles: steelhead are migratory (born in rivers but move to the ocean or #GreatLakes), while rainbows are river homebodies #25DaysofFishmas

@SolomonRDavid @DrFishSG @ericrsails @donaldorth @WildlifeBioGal @ReelAngle @UWiscSeaGrant Fun fact: my avatar from @Blackmudpuppy even features a freshwater drum! #25DaysofFishmas

@DrFishSG @ericrsails @ReelAngle @SolomonRDavid @UWiscSeaGrant @donaldorth @greatlakescisco @WildlifeBioGal @LakeSuperior But like helping Scrooge learning the error of his ways, this Ghost of #Fishmas Past tells us all is not lost: many researchers + agencies across the #GreatLakes are working to protect + restore native Ciscoes - check out #CiscoInferno + tagged tweeps for more! #25DaysofFishmas

@SolomonRDavid @DrFishSG @ReelAngle @ericrsails @donaldorth @UWiscSeaGrant @WildlifeBioGal While native to east Asia, goldfish have been widely-introduced across the world because of their popularity as aquarium + pond fish. They’ve been found in every contiguous US state + all the #GreatLakes #25DaysofFishmas

@SolomonRDavid @ReelAngle @DrFishSG @UWiscSeaGrant @ericrsails @donaldorth @WildlifeBioGal Adult silver lampreys use their suction-like mouths to attach to a host fish + feed on flesh/body fluids (yum). They live 12-20 months as parasites before migrating up streams to spawn, and then die after spawning (like salmon!) #25DaysofFishmas

@SolomonRDavid @ReelAngle @DrFishSG @UWiscSeaGrant @ericrsails @donaldorth @WildlifeBioGal Silver lampreys are members of a group of jawless, ancient fish called Petromyzontiformes - their name “Ichthyomyzon” literally means “fish-sucker” (Greek, ichthys = fish + myzo = to suckle) #GreatLakes #25DaysofFishmas

@ToledoZoo this absolute unit of a pacu (the vegetarian cousin of the piranha)

An old sketch of an American eel for the Thanksgiving-themed #SundayFishSketch, as eels were among the fish eaten by the Wampanoag people of Massachusetts. While eels were once abundant along the Atlantic coast, they - like other migratory fish - were impacted by dams.

@JamesMunro5 @TheScaryNature @GilesMacDonogh That's a good question! While there are at least 1200 fish considered "venomous", many deliver venom through spines (e.g., stonefish). But, there are a handful of fish species with venomous fangs, like the combtooth blennies (Meiacanthus) https://t.co/xNu43ktGE2

When you think "biodiversity", you might think of coral reefs or tropical rainforests, but the southeast U.S. is home to a truly amazing number of freshwater fish species - 493 species, or ~62% of U.S. fish species (Map: https://t.co/2IcQweWvrN) #BiodiversityDay
