Although the Aquarium is constantly changing up animals inthe exhibits or building new habitats, it’s not often that we get to celebrate the opening of a brand-new gallery. With a building like ours, space is at a premium, so when we add something big, something old often has to leave to makeroom for the new and exciting addition.

In a little over two weeks, the Aquarium will cut the ribbonon Scuttlebutt Reef. This exciting new collection of exhibits is taking the place of the Boneless Beauties gallery and is the first major addition to our campus since 2023.

Scuttlebutt Reef shines a spotlight on many smaller marinespecies with highly specialized (and often misunderstood) adaptations. These oddball superpowers allow them to — among other things — glow in the dark, suction themselves to rocks, refract light, dig without any limbs and punch well above their weight class.

The new gallery opens on March 7, 2026, but in the meantime,this episode will preview the new space, explore its origins and introduce many of the species you’ll soon be able to see there.

Whether you’re shoveling your way out of lake effect snow or get goosebumps and uncontrollable shivers whenever the thermometer dips below 50, winter can be a tough time of year. That’s especially true for wildlife, which can’t just keep nudging up the thermostat whenever they feel a bit of a chill.

So what tactics do animals employ to make it through this tough time of year when food resources are thin on the ground, freshwater freezes solid and just a thin layer of leaf litter is all that’s separating them from exposure to the latest bomb cyclone?

In this episode, several Aquarium experts point out the differences between hibernation, torpor and brumation, explain where bees go in the winter and how bears can manage to go months between bathroom breaks.

Before the advent of photography and — obviously — videography, naturalists had no choice but to rely on their artistic skills if they wanted to preserve a visual record of their work.

Whether an impromptu sketch or a laboriously detailed drawing or painting, scientific illustrations were a vital means of sharing scientific research and observations with the public. They were also, in many cases, absolutely beautiful works in their own right.

In this episode of the show, we connect with a modern-day scientific illustrating savant, Joe Tomelleri, who is renowned the world over for this exactingly detailed depictions of freshwater fish. Using nothing but his skill, carefully preserved specimens and a set of colored pencils, he toils for dozens of hours to produce a single image that replicates identifiable characteristics down, without exaggeration, to individual scales.

While exploring the galleries of the River Journey and OceanJourney buildings, artwork might not be what you’re focusing on during a visit to the Tennessee Aquarium, but maybe you should take a beat to give it some love.

Stylized depictions of our living collection are all over campus courtesy of a pair of extremely talented and industrious graphic designers.

In this episode — the first of a two-part mini-series — we’ll explore the overlap between art and science, learn about the role our graphic designers play in achieving our mission and how they heck they translate the recognizable features of an animal like an Epaulette Shark into a stylized illustration.

For many people, a visit to a national park is like making a pilgrimage, a chance to commune with nature in a setting of remarkable beauty and peace.

The United States is a big country, though, and even with more than 430 designated national parks, every region didn't get an equal share of the spoils. Although spectacular examples exist, such as the Great Smoky Mountains, Acadia and Everglades, only about 20% of national parks are east of the Mississippi.

If you live far from a national park and want to seek solace in nature closer to home, your best bet is probably one of the almost 10,000 state parks. These sites are distributed far more evenly throughout the country and enshrine vistas every bit as beautiful and grandiose as those in national parks. Even better, there's probably one (or several) just around the corner from wherever you happen to be listening.

In this episode, the Studio Dive Cage goes on the road to Old Stone Fort State Archaeological Park about an hour west of Chattanooga. There, guests from The Tennessee Conservationist — the official magazine of Tennessee State Parks — and the park discuss the misnomer that gave Old Stone Fort its name, why the nearby Duck River is so biologically rich, the role state parks play in democratizing access to nature and the future of Tennessee state parks.

For many species, the arrival of humans to the neighborhood is usually a portent of bad things to come. The alterations we make to our environment often wreak havoc on the other animals that share those wild spaces with us.

No matter how you slice it, ours is the dominant species on the planet when it comes to shaping the world around us to suit our wants and desires. But that power also can be wielded to enact positive change, and when humans — especially an entire community of them — rally to a species' defense, their impact can be potent.

In this episode, you'll learn about one small Tennessee community's response to learning about the plight of a critically endangered minnow living on a nearby ridge. Like all good neighbors, they came together in defense of this hard luck fish, and the story of how and why that came to happen is the subject of this discussion.

At the Aquarium, a LOT of work is done by full-time team members, from seeing to the needs of the animals and keeping the lights on to hosting special events and ... yes, podcasting.

During their visit, however, many guests benefit in innumerable ways from the dedicated efforts of hundreds of volunteers. From prepping diet for sharks and watering tropical orchids to hosting underwater educational programs, volunteers make the Aquarium world go round.

In this episode, our volunteer coordinators join a long-time volunteer diver to discuss why folks are so generous with donating their time and effort to the Aquarium and ways you — yes, YOU — can sign up to help out, too.

As the last kitten-a-day page falls from the calendar, we're taking a moment to look back on the first full year of The Podcast Aquatic and celebrate the many high points for the show.

Of all the topics we've covered this year, though, host Casey is most proud of our (admittedly fairly recent) discussion about how the Aquarium takes pains to ensure it is as accessible to as broad an audience as possible.

Take a listen to this touching discussion as you toast in 2026. The show will be back up and running next week with a new episode to kick off season two!
