  • Volcanos

    🔥✨🌋Step back in time with the volcano exhibit and discover Duluth's fiery origins  When hot magma sculpted the earth beneath our feet, later soothed by waves of cold water. 🌊 (Basaltic lava above ground, Magma below ground)

    🌊 The Great Lakes are cradled in basins of volcanic rock formed by melting glaciers. 🗿 Spot the dark, sturdy *basalt rock – from the winding Lester River to the serene Leif Erikson Park, and the cascading Gooseberry Falls. 🏞️ Basalt rocks are a familiar sight around Lake Superior, telling a story that began, long before human history began.

  • Coral

    ✨🌊They may not have eyes, a heart, or a brain, but corals are very much alive!  🌊Believe it or not, corals are animals, not plants or rocks. 🌊 Corals have a unique diet; they don't make their own food but feast on plankton —tiny organisms that drift through the water.(think of the character from SpongeBob) 🌊 It's a slow dance, but they can move!  🌊 Some corals can live for an astonishing 5,000 years.  🌊 Let's appreciate these marine marvels that build the underwater cities we call reefs.

  • American Alligator

    📜 With a lineage dating back to prehistoric times, the American Alligator is a relative to the dinosaur and shares the planet with only one other species, the Chinese Alligator. 🐊  🌾 These powerful reptiles make their homes in the freshwater marshes of places like Texas, North Carolina, and Arkansas. 🥚 They are skilled nest builders, laying their eggs amidst sticks and leaves close to water's edge. 👃 Distinctly different from their crocodile cousins, you can spot an alligator by its U-shaped nose (while crocs sport a V-shaped one!). 🤔 While it's said that crocodiles are the more aggressive of the two, it's always wise to keep a respectful distance from both. 💧 Unlike saltwater-loving crocodiles, alligators prefer the fresh waters. 🌿🌎

  • Moon Jellies: Jellyfish

    💧Drifting through the seas with a ghostly grace, these jellyfish are a marvel of nature, lacking a brain, eyes, or heart, surviving on plankton. Their mesmerizing hues of pink or blue aren't just for show; they're a reflection of their diet. Despite their short lifespan of 1-2 years, Moon Jellies have existed for over 500 million years (predating dinosaurs). With a sting that's more a whisper than a shout, their translucent (moonlike), lunar-like bells move rhythmically through the water, seemingly unaffected by pollution or ocean warming. Witness the miracle of their two stages - life cycle, from the anchored polyp (small stalk attached to a rock and then breaks free) to the free-swimming medusa (adult bell-shaped), and marvel at their delicate skin that breathes in the sea itself (skin collects oxygen from water). 🌊 Underside of the bell (very center) is for food (and waste!)  🌙

    🍂🌞 Slithering through the landscapes, it's known for its impressive longevity. Living up to 20-25 years, this species thrives in Minnesota's varied habitats. These nonvenomous serpents play a crucial role in the ecosystem, preying on small mammals like mice, squirrels, and even ground-nesting birds. In the warm embrace of summer, from June to July, the female Bullsnake carefully deposits 5-19 eggs in the nurturing earth. They spend their daylight hours active or resting in rodent burrows that they took over. They're equipped with a specialized, slightly pointed nasal shield for digging. True to their name, they can emit a bull-like snort when disturbed. And if you encounter one, it could rear up, hiss, and lunge to ward off any perceived threats.

  • Seahorses

    🦐🌿 Delicate dancers of the sea, seahorses captivate with their unique charm and their heads shaped like the head of a horse. Their tails serve as anchors. A twist of nature—fathers, not mothers, carry the unborn in a brood pouch akin to a kangaroo's. Tiny newborns emerge no bigger than a jellybean, propelling into a world where their voracious appetites lead them to feed constantly, a necessity since they lack stomachs and need to eat most of the day sucking up food through their snout. Seahorses form long-term partners, engaging in enchanting morning rituals of dance that can span from fleeting moments to hours. Their swim may be clumsy, propelling themselves vertically through the water, but it's their independent eye movements that give them an otherworldly gaze. Living in tropical and coastal regions, with lifespans ranging from 1-5 years, these creatures express discontent with a distinctive growl, recorded by high-tech means. And in a display of surprising affection, they've been known to grow attached to human caretakers, eating from hands, hitching rides on fingers, or greeting with a twirl.  🌊

Mother Nature plays a temperature game to determine their gender (boy or girl) before they even hatch. Sunbathing isn't just for relaxation; it's a clever tactic to shake off unwelcome parasites and leeches. ☀️🛁 As winter whispers, they tuck into the mud, slowing down their bodies to the chill of their surroundings in hibernation. But don't let their peaceful demeanor fool you; these turtles can snap with a bite if caught off guard, and hiss if they feel threatened! 😯🐾

    Swimmers and sun-worshippers, by nature, they have a, flat shell and sport vibrant streaks of red-orange and yellow across their neck, legs, and tail, with sunny spots on their heads. And with an external eardrum, they’re listening in on the world above water. 🐢

  • Carp

    🐟💥 🌍 Dwellers of European and Asian waters, carps have voyaged far from home, turning into unwelcome guests in U.S. rivers. 💧 With their oily sheen, these freshwater fish have slipped into ecosystems, their appetites for plankton leaving little for the native residents. 🚧, escaping from southern aquaculture havens into the wild expanse of the Mississippi River, fueled by floodwaters. 🛶 The silver carp, notorious for jumping, pose a literal leap of danger, startling boaters. 🌱🐠

    🐠 Carp are fish with shiny, silver bodies. They are part of a group of fish species native to Asia. Carp were originally brought to the U.S. to help clean algae and weeds in fish farms. They escaped into the Mississippi River during floods in the 1970s and quickly spread.

    Impact on Native Fish:

    Carp eat huge amounts of plankton, which is the base of the food chain for many fish species. By eating all the plankton, they starve native fish, disrupting the entire ecosystem.

    Carp in the Great Lakes:

    Carp have not fully invaded the Great Lakes yet, but there is concern they might. Barriers are in place to stop them from entering through the Mississippi River.

    Flying Fish Danger:

    Carp can jump high out of the water when startled, sometimes hitting boaters and making rivers unsafe for recreational use.

    Activity Idea:

    Carp Jump Simulation: Use a beach ball or inflatable fish. Toss it into the air and discuss how flying carp might feel to boaters. It's a fun way to imagine the challenge and danger carp pose!

    🌙🌳 From the woods of Minnesota, emerges the opossum, an often misunderstood yet fascinating creature of the night. 🦷 Sporting a remarkable set of 50 teeth, they are ready for any culinary adventure, from the wild to the wastebin. 👶 A mother's pouch becomes a snug nursery for 5-8 tiny beans, though she might welcome up to 25!  🐾 Equipped with prehensile tails. 🌚 As nocturnal foragers, they're the unseen custodians of our backyards, clearing out pests like ticks, and, yes, even unwanted rodents. 🗑️ 🛑 In the face of danger, their dramatics unfold—a hiss, a belch, or perhaps a theatrical "death," complete with an odor finale. 🕓 If they play dead, it's not a mere act; they can lock into a stiff pose for hours. 🤍

The Invisible Ball
  • Ballast Water

    What is Ballast Water? Big ships use ballast water to stay stable while they travel. They fill their tanks with water from one place to help balance the ship when it's not carrying cargo. When they reach their destination, they dump the ballast water out. This helps them stay safe at sea.

    Why is Ballast Water a Problem? The water ships pick up often contain plants, animals, and tiny organisms from the first location.

    When the ballast water is dumped in a new place, these organisms (called invasive species) enter an ecosystem where they don’t belong. In the Great Lakes, invasive species like zebra mussels and round gobies were introduced this way. These species:

    Crowd out native plants and animals.

    Change the food chain, making it harder for native fish to survive. Damage the environment and the economy, affecting fishing and recreation.

    How Are We Helping? Ships now follow ballast water management rules to stop the spread of invasive species: Ballast Water Exchange: Before entering the Great Lakes, ships replace their ballast water with ocean water, which is less likely to carry invasive species that can survive in freshwater.

    Onboard Treatment Systems: Some ships use filters, chemicals, or UV light to kill organisms in their ballast water. Regulations: Governments and organizations work together to check and enforce these rules.

    Activity: Build a Solution. Imagine you’re an engineer. How would you stop invasive species from spreading through ballast water? Draw your idea for a new ballast water treatment system. Share your solution with others!

    By learning about ballast water, we can understand how our actions affect the environment and what we can do to protect amazing places like the Great Lakes!

  • SS America

    See pieces from the SS America, it was a steamship that carried passengers and cargo on Lake Superior, including stops in Duluth, MN. On its final voyage in 1928, it sank near Isle Royale after hitting a reef while navigating in foggy conditions. The ship had safely dropped off most of its passengers earlier, and it’s often mentioned that the pilot, on his first day on the job, misjudged the reef. Everyone was saved. The ship was not retrieved, partly because of the Great Depression, which made salvage efforts unaffordable. Today, the SS America is a popular dive site and a time capsule of life from the early 20th century, with artifacts like dishes and furniture still visible underwater. This ship's story offers a fascinating glimpse into life on Lake Superior and the challenges of early maritime travel.
