ClassX Video Lessons Youtube Channel Curiosity Stream The Secret World of the Aquarium After Dark | Night At The Aquarium
Have you ever wondered what happens in an aquarium when the lights go out? It’s a magical place where sea creatures live, and sometimes, they have their own little adventures. My name is John Oie, and I used to be the director of this aquarium for 39 years. Now, I help make sure everything runs smoothly, even at night. Recently, we’ve had a mystery on our hands—some of our fish have been disappearing!
Every night for a week, a fish has gone missing. Our first suspect is the clever octopus. She’s known for being an escape artist, which means she can sneak out of her tank if she’s bored. Did you know that octopuses have a central brain and smaller brains in each of their eight arms? That’s why they need puzzles to keep them busy. Tonight, her dinner is hidden in a maze, and she has to figure it out to eat. She stretches her arms like rubber bands to reach the food, but it’s tricky!
Next, we check on the baby swell sharks. They’re still in their egg cases, growing and getting ready to hatch. These little sharks stay in their eggs for about a year, eating the yolk inside. When they’re hungry enough, they break out and start exploring the world. Could one of them be causing trouble? We’ll have to keep an eye on them!
Did you know jellyfish have to be born twice before they become adults? It’s like a story! First, they’re tiny larvae that float around the ocean. Then, they settle down and turn into polyps. But soon, they change again into medusas, which are the jellyfish we recognize. It’s like they go on a big adventure before growing up!
One night, a fish called a fringehead disappeared. We thought it was gone, but it turned out there was a fight for the “king of the shell” title. The fish had just hidden away after losing. Sometimes, things aren’t what they seem, and we have to look closely to find the truth.
Finally, we return to the swell shark. It’s ready to hatch from its egg case! It pushes and wiggles until it breaks free. But don’t worry, this little shark isn’t dangerous. In fact, most sharks are more scared of humans than we are of them!
In the end, we realized there wasn’t a mystery after all. We had just counted the fish wrong! Plus, we had a new angel shark that needed to learn some manners. So, the mystery was solved, and everything was back to normal. There’s never a dull moment at the aquarium!
Exploring the aquarium at night shows us that there’s always more to learn about the amazing creatures that live there. Whether it’s solving mysteries or discovering new facts, the underwater world is full of surprises!
Imagine you’re an octopus trying to find your dinner! Create a simple maze using paper and markers. Then, use a small object like a marble to represent the octopus. Try to navigate the maze to reach the “dinner” at the end. This will help you understand how octopuses use their intelligence and problem-solving skills.
Draw a timeline of a swell shark’s life, starting from the egg stage. Use colored pencils to illustrate each stage of development. This activity will help you learn about the life cycle of sharks and how they grow and change over time.
Write a short story about a jellyfish’s journey from a tiny larva to a medusa. Include illustrations to show each stage of its transformation. This will help you understand the fascinating life cycle of jellyfish and how they adapt to their environment.
Become a detective and create a comic strip about the mystery of the missing fish. Use your imagination to come up with different scenarios and solutions. This activity will help you think critically and creatively about problem-solving.
Design a board game that takes players on an adventure through an aquarium at night. Include challenges and mysteries to solve along the way. This will help you learn about the different creatures in the aquarium and how they interact with each other.
Sure! Here’s a sanitized version of the transcript:

[Music] It’s no secret that an aquarium is a place of wonder, where creatures of the sea become a part of our lives and we a part of theirs. But it wasn’t until I was here that I realized the true magic happens when the lights go [Music] off. I can finally say it feels good to be back. My name is John Oie, and for 39 years, I was the director of this aquarium. Now, I’m an overseer—it’s a full-time job keeping everyone happy. Don’t believe me? Well, at night, this place comes [Music] alive.
But tonight, I’ve been called on because there’s a mystery afoot. Every night for the past week, another one of our fish has gone missing. We’re going to have to get to the bottom of this. Everyone is normally so well-behaved. Our first suspect is the smartest girl in here, the octopus. She’s known around here as a bit of an escape artist. Could she be responsible? I always used to say, four times the arms, four times the smarts. You see, she has a central brain, but in addition, octopuses actually have many brains in their eight arms. That’s why she needs what we call enrichment—she needs to be challenged to keep her out of trouble. Tonight, this enrichment comes in the form of a puzzle, which is also her dinner. Her mind tries to figure out the maze [Music].
Like a rubber band, she stretches her arms to three times their normal length as she tries to reach all the way down the tubes, but the maze is long, and the little crabs are just out of reach. Oh, she’s frustrated! What’s this? A crab’s missing? Oh no, little guy, this maze isn’t for you. She’s got to be seeing [Music] this. Well, she didn’t quite figure out the puzzle, but I think it’s safe to say she’s too preoccupied with dinner to go after our missing fish. Check her off the suspect list.
If I recall, the last time this happened, our big clue was when we found a baby shark in the sardine tank, so it’s probably worth keeping an eye on these baby swell sharks for now. They’re cozy inside their egg cases, all in different stages of development. As they grow, they consume the egg yolk until nothing is left. When they get hungry, they’ll have to emerge into the world. After a year in the egg case, this guy is ready to pop. We’ll have to see if he gets himself into any [Music] trouble. This aquarium always has a way of surprising you.
Speaking of surprises, did you know jellyfish need to be born twice before they grow up into adults? It’s storytime! Imagine Mom and Dad jellyfish are on a long road trip through the ocean, and they love each other very much. Now there’s a baby. This baby is not a jellyfish and goes on its own little road trip before deciding to settle down, changing into a polyp. But soon, the polyp decides it wants to see the world, not be tied down by its polyp form, so it begins to change again into a medusa, and now it’s ready to give [Music] birth to a baby jellyfish taking its first swimming strokes—just the cutest little gelatinous umbrellas I’ve ever seen. Eventually, these baby jellyfish grow up to be full-grown jellyfish, and one day they’ll find their own road trip partners, starting the happy process over again. Jellyfish always teach me to keep an open mind to weird possibilities.
I’m wondering if we’re missing a clue with our mystery fish. One night, one of these fringe heads disappeared, but in the end, we realized a battle for king of the shell had broken out. Former friends became rivals, using their colorful mouth displays for [Music] intimidation. After losing, the missing fish had just retreated deep into a corner, hidden from view. I hate to say it, but it might be worth double-checking and seeing our fish [Music] again.
Before we do, though, let’s completely tie off our suspect list and come back to our swell shark from [Music] earlier. We’re just in [Music] time! When he’s ready, he’ll push through the egg casing. It’s tight, though, and difficult. Is that mischief I see in those eyes, or is he just [Music] stuck? Here we go! [Music] Behold the monster! Wait a second, this is what we’re afraid of. He couldn’t hurt a fly. You know, as a human, 95% of sharks are terrified of us, but even as a fish, I don’t think there’s anything to worry about from this [Music] shark. Look at them all! It’s safe to say that he too is off the suspect list.
If it wasn’t the swell shark or the octopus or any of the usual suspects, maybe my hunch was right, and we have just been counting the fish wrong, and there never was a mystery [Music] here. Oh right, we collected an angel shark from the wild last week. We’ll have to teach him some [Music] manners. Well, mystery solved, and my job here is done. Never a boring night at the aquarium!
