Meet a very important native fish that gets no respect: the White Sucker! Turns out this fish is a total catch! Kids love 'em. Walleyes and muskies love 'em. Eagles love 'em. Otters love 'em. Fishermen and fisherwomen love 'em. Katrina and Guy are joined by guests Tyler Winter (Native Fish for Tomorrow) and Rick Bruesewitz (Minnesota Department of Natural Resources).

Meet big-gaped Green Sunfish! This beefy, bass-like sunfish is fun to catch and beautiful to behold. Learn about its habits, where it's found, how to catch it, where it fits in the fish family tree, and more.

Put on your spelunking gear and get ready to head to Key Cave National Wildlife Refuge in northern Alabama. Key Cave is the only place in the entire world where the bizarre-looking Alabama Cavefish is known to exist. By the time you finish listening you'll either be glad or jealous you didn't soil your pants sliding down gray bat guano to meet this amazing fish. We are joined by special guests Nick Wirwa with the U.S. Fish and Wildlife Service and Bernie Kuhajda with the Tennessee Aquarium.

Meet a soft and flabby wonder with the smallest brain-to-body weight ratio of any vertebrate and a name that's bound to stimulate conversation. Two guests deep dive into assfish territory with us: Peter Auster from Mystic Aquarium and the University of Connecticut, and Brittany Petersen from our National Conservation Training Center (and formerly with the Northeast Canyons and Seamounts Marine National Monument).

You’ll be hooked when you meet this shoal habitat specialist and Apalachicola-Flint-Chattahoochee River native. Learn how to think like a shoalie, understand the importance of knowing its prey, and pursue it safely in class 3 rapids on foot or from a raft. Fly tier extraordinaire Fletcher Sams and Shoal Bass enthusiast Jay Shelton are our guests.

Meet a cucumber-scented fish that feeds the masses and sometimes crashes. Our guests are Yumi Arimitsu with the USGS Alaska Science Center Seabird and Forage Fish Ecology Program and Seabird Biologist Robb Kaler with the Marine Birds Section of our Alaska Division of Migratory Bird Management.

Come on an adventure into high elevation and rugged terrain to find Mexico's diverse native trout. Illustrator and Mexican native trout enthusiast Joe Tomelleri takes us on a journey of discovery and art inspired by stunningly beautiful fishes.

Hey, you guys! One distinguishing feature of invasive carp is eye placement at or below the mouth opening. They also have a very particular set of skills that makes them so successful at outcompeting the native fish you love. Fish Biologists Mark Fritts and Tyler Gross join the conversation from our Lacrosse Fish and Wildlife Conservation Office in Wisconsin and our Lower Great Lakes Fish and Wildlife Conservation Office's Ohio River Substation in West Virginia.

Anglers take note...this fish is a sleeper, not a snooze! Meet the Bigmouth Sleeper, the natural "top dog" in Puerto Rico's streams. The name tells you all you need to know about the appearance and behavior of this underappreciated fish. Augustin (Gus) Engman from the University of Tennessee joins us again to dig further into the native fishes that inhabit the island, including what we know about this fish and how to get it on the end of your line.

If you happen to be an unfortunate men’s size 7 Nike shoe, one of 50+ species of octopus, a big shard of plastic or rope, or any number of reef, oceanic, and deep sea fish, you might find yourself undigested in a Longnose Lancetfish’s stomach! That’s after you’ve been trapped between cage-like teeth with no get-out-of-jail-free card. That said, we’d like to give a big thank you to lancetfish for being amazing samplers of the marine environment and helping scientists understand ocean food webs and the pervasiveness of plastic pollution! Our guests are Emily Contreras with NOAA Fisheries in Honolulu and Lauren Flynn with our Alaska Maritime National Wildlife Refuge.
