For a fish that first appeared alongside dinosaurs and survived the calamity that wiped them out, the Lake Sturgeon has had a hard last half-century in Tennessee.

Once abundant in the state's waterways, wild Lake Sturgeon were last seen in Tennessee in 1963.

In 1998, the Tennessee Aquarium was among the organizations that founded the Lake Sturgeon Working Group. Since then, the group members have been hard at work raising and releasing baby Lake Sturgeon in hopes of re-establishing a stable wild population in the Tennessee and Cumberland rivers.

This year, that effort celebrates 25 years of releasing sturgeon raised in human care, and recent findings by wildlife managers suggest those years of effort may finally be bearing fruit.

To the general public, the acronym "AZA" might be largely meaningless, but in the zoo and aquarium world, it's associated with the gold standard by which all aspects of a zoological organization is measured, especially the animals' well being.

The Association of Zoos and Aquariums was founded more than 100 years ago in 1924. It now comprises more than 9,000 individual members and has accredited more than 250 institutions worldwide.

In this episode — recorded live at AZA's annual conference in Tampa, Florida — AZA President & CEO Dan Ashe talks about what it means to hold zoos and aquariums to this incredibly high standard, how it (like its member institutions) has had to change over the last century and the pride he takes in AZA's many global conservation-focused efforts around the world.

From impossibly flexible, boneless bodies and mastery of camouflage to an over-abundance of brains and hearts, octopuses are like aliens come down from on high to boggle the minds of biologists.

In this short-form, Mic Droplet episode of the podcast, the Aquarium’s resident octopus specialist helps celebrate World Octopus Day by ticking off a few of the most-noteworthy facts about these amazing cephalopods and explains how in the actual heck you weigh a 50-pound octopus.

When it comes to the most impressive migrations in the animal kingdom , there are a few obvious standouts: the pole-to-pole voyage of the Arctic Tern; the horizon-spanning race of Wildebeests across the Serengeti; the bear-dodging spawning runs of Chinook Salmon.

In the insect world, however, pretty much everything pales in comparison to the daunting voyage of Monarch Butterflies from Central Mexico to Canada and back again. Every year, these tiny, beautiful insects embark on this trip, which takes multiple generations to complete ... except when it doesn't.

At the onset of fall, a single generation of butterflies completes the entire trip back to Mexico, a task that sounds laughably impossible for a featherweight insect with gossamer-delicate, three-inch wings. Yet they do it, every ... single ... year.

The Tennessee Aquarium sits squarely in the middle of the migration route for the eastern population of Monarch Butterflies, making it a prime viewing location for these orange-and-gold beauties as they make their way northward each fall. In this episode, the Aquarium's senior entomologist talks about Monarchs set people's hearts a-flutter, the biological processes that allow them to undertake their unbelievable trip and steps society is taking to protect Monarchs from the greatest threat of all: us.

It’s pretty much inarguable that sharks get a bad rap.

In a given year, a handful of humans are bitten by sharks, and of these, an even smaller number result in serious injuries or fatalities.

Flip the script, however, and sharks are far more likely to be the victims of "human attacks." Most data suggest about 100 MILLION sharks die each year due to intentional harvest, commercial by-catch or other human activity.

Yet despite this decidedly lop-sided relationship, many of us continue to fear sharks due to reports of shark bites that over-emphasize the aggressiveness of these sleek marine predators.

In this episode, Cristina Zenato -- a self-described "shark listener" -- talks about her and other ecologists' quest to understand how sharks behave, a view informed by countless positive interactions with them as a lifelong diver and researcher. She also discusses her role in the new giant-screen film, Shark Kingdom 3D, which is now playing at the Tennessee Aquarium IMAX 3D Theater!

At the Aquarium, we have animals of all sorts, from the beautiful and benign to graceful and powerful. Some of our residents could even, in some circumstances, be considered "dangerous."

How, then, do you see to the needs of species whose adaptations present a serious risk to their caretakers? What tools do you need? What mindset do you have to adopt?

In this episode, three caretakers of animals such as Electric Eels, Pacific Sea Nettles, American Alligators and ... River Otters? ... talk about how they approach ensuring the health of animals that pose a risk to theirs.

Every year, hundreds of thousands of visitors explore the galleries of the Tennessee Aquarium. The hope is that those experiences help guests to form a meaningful bond with the natural world and to better understand the importance of freshwater and how our behavior impacts it. That aim is the same for every guest, regardless of their sensory challenges or whether they are a person living with an impairment.

In this episode, we talk about the efforts the Aquarium has made to improve accessibility, including being one of the first organizations in America to be certified as sensory-inclusive by Birmingham, Alabama-based nonprofit KultureCity.

We'll also hear directly from an Aquarium member about how those efforts to improving accessibility have directly benefited his son, who lives with autism, by making the Aquarium a safe, inspiring, joy-filled place to visit.

Episode Cast

• Casey Phillips, host, senior communications specialist
• Mara-Lynne Payne, director of inclusion, equity and diversity
• Benjamin Sheffield, Aquarium member, father to "Little Man"
• Uma Srivastava, executive director for KultureCity

If you're ever in the wild and encounter an animal that looks ghost-like — pale skin, scales or fur — your immediate thought might be that this is an example of albinism. Look a little closer, though, and there may be some tell-tale signs that you've actually chanced on something different, if just as interesting.

In our first-ever Mic Droplet, a shorter-format version of The Podcast Aquatic you know and love, we chat about leucism, how it differs from albinism and an exciting new opportunity to see it during your Aquarium visit.
